4 * Tested successfully on AIX
7 * fix a bug on struct sizeof computation, which prevented the
8 exchange of arrays of structs in some conditions
9 - added a regression test about this in datadesc_usage
10 * Allow the exchange of 0-long dynamic vectors.
11 - for that, use -1 as indicator of dynamic size instead of 0
12 - This implied to change any size from unsigned long to long,
13 reducing a bit communication abilities, but I guess that with
14 64bits being quite common, this is more than enough.
15 - This also induce a protocol change, thus bumping network protocol
16 version from 0 to 1 (if we have external users, we have to get
17 clean on that point too ;)
18 - added two regression tests about this in datadesc_usage
19 * Be more verbose when propagating local exceptions
21 * Display the status of simulated processes when receiving SIGINT in
25 * Allow to control the simulation from a trace file.
26 New functions MSG_action_register() and MSG_action_trace_run()
27 The first one allows to associate a function execution to each
28 kind of action while the second one parses a trace file and
29 triggers the corresponding actions within the system.
30 For now, only a toy example is provided in examples/msg/actions
31 * Add an exemple of process migration in examples/msg/migration
32 * Fix a bug in task exchange which broke MSG_task_get_sender()
33 Add a teshsuite regression test for that.
34 [Bug: if MSG_task_get_sender() is called after sender exit,
36 * Fix a bug which prevented suspend/resume to work properly
37 * Display the status of simulated processes when receiving SIGINT
38 This fixes a regression of v3.3. due to the introduction of SIMIX
39 * Bug fixing in failure management:
40 - trace could not start by a failure at time 0
41 - failure during communications were not working
44 * Add SIMIX_process_set_name() to change the name of the current
45 process in the log messages.
46 * Store smx_hosts in a dict since we only retrieve them by name
47 * Move the configuration infrastructure to surf
50 * Move the configuration infrastructure to surf
53 * Also include strbuff from xbt.h public header
54 * xbt_ex_display(): do not free the exception after displaying
55 This allows to do more with the given exception afterward.
56 Users should call xbt_ex_free() themselves.
59 * Massive internal cleanups:
60 - Store internal structures on processes instead of hosts (allows
61 to have more than one process per host, in addition of being more
63 - Cleanup the initialization/finalization process
64 - Kill a whole bunch of unneeded synchronization:
65 processes run in exclusive manner within the simulator
66 - Move queues from global tables to process data fields
68 - now accept -platform and -hostfile arguments
69 - Pass the right rank value to processes according to the hostfile
70 * Compile the examples by default, and use them as regression tests

78 SimGrid (3.3) stable; urgency=high
82 * JAVA BINDINGS for MSG (you dreamt of them? We made them)
85 * Introduce the SIMIX module: factorize code between MSG and GRAS.
88 Until now, GRAS were using MSG as an interface to SURF. It was
89 quite difficult because both interface have several differences
90 (MSG channels vs GRAS sockets were the most notable point).
92 This also opens the gate to SMPI (which should occur soon) and speed
93 up simulations by to 40% (even if it were not the main goal).
95 **************************************
96 *DO NOT MIX 3.2 RESULTS WITH 3.3 ONES* Simix may changes simulations!
97 **************************************
98 The point is that events occuring at the exact same timestamp are
99 not scheduled in the same order with the old and new version. This
100 may be enough to completely change the execution of simulations in
101 some cases. Sorry for the inconvenience.
103 * Cleanup and upgrade the XML format to push further scalability
104 issues (check http://hal.inria.fr/inria-00256883/ for more info)
106 * Improve the testing infrastructure with tesh. Now a very large part of
107 the code is tested not only by being run but also by checking that the
108 output match an expected output [Mt].
110 * Move on to FleXML v1.7 for the embeeded XML parsers. This version
111 is really less memory-demanding, which should allow you to use
112 larger files in SimGrid [AL].
114 * Inform valgrind about our contextes, so that it becomes usable
115 with the default (and more effecient) version of SimGrid
116 [contributed by Sékou Diakite, many thanks]
119 * Introduce a listener thread in charge of receiving incomming
120 messages from the network. It allows to overlap communication and
121 computation but most notably, it removes some stupid deadlocks due
122 to the fact that so far, a process could not send and receive at
123 the same time. This made most non trivial communication schema
125 * Convert the PIDs from long int to int to match the MSG ones (and
127 * New function: gras_agent_spawn() to launch a new process on
128 current host. Only working in simulation for now. [Mt]
129 * New function: gras_os_hostport() returning a constant form (ie,
130 not needing to be freed) of "gras_os_hostname():gras_os_myport()"
133 * Make the backtrace of exceptions more human readable [Mt]
134 * New module: xbt/str [Mt]
135 a ton of string utility functions (split, join, printf to a newly
136 allocated buffer, trim, etc)
137 * New module: xbt/hash [Mt]
138 SHA1 hashing algorithm (more to come if needed)
139 * New module: xbt/synchro [Mt]
140 synchronization tools (mutex and conditions) working the same way
141 in simulation and in real life (mainly useful for GRAS, but not
143 * New module: xbt/queue [Mt]
144 classical producer/consumer synchronization scheme
145 * xbt_dynar_new_sync() creates a synchronized dynar. All access
146 (using the classical functions will get serialized) [Mt]
147 * Make dictionary internal table dynamic. No need to specify its size
148 anymore; functions xbt_dict_new_ext() and xbt_dict_hashsize_set()
150 * Make sure the log channels are organized as a tree under windows
151 (because of ANSI C compatibility issue, any channel were child of
155 * Cleaned many thing in surf and fixed a few bugs [AL].
156 * Add a nice command line configuration mechanism to compose models [AL].
157 * Add a new model for parallel tasks (ptask_L07) that is less buggy than
158 the previous one (KCCFLN05). It relies on something that looks like
159 a max-min sharing mechanism but cannot be written as such. A new solver
160 was thus designed [AL].
161 * Add a new solver to lmm. Based on Lagrange optimization and
162 gradient-based descent, it enables to efficiently maximise systems s.a
164 sum f_i(x_i) s.t Ax<= b with A_{i,j}>=0 and f_i a concave function.
166 This solver enables to propose two new network models for TCP Reno and
167 TCP Vegas based on Low's work. These models still need to be fully
168 tested though [Pedro Velho].
171 * Bug fix in SD_simulate. Now the time bound given as argument is
173 * Use the new parallel task model (ptask_L07) as default.
174 * Use the SURF command line configuration mechanism.
175 * 0-size tasks (for synchronization) should now work.

179 SimGrid (3.2) stable; urgency=high
183 We still experience issues on this platform, but we believe that at
186 GRAS API BREAKAGE (for simplification purpose, sorry):
187 * the gras_msgtype_by_name is not used anymore. Instead of
188 gras_msg_send(toserver, gras_msgtype_by_name("request"), &request);
189 you can write (and must)
190 gras_msg_send(toserver, "request", &request);
191 - If you still want to pass a gras_msgtype_t to the function (to cache
192 the type and avoid the lookup time), use the gras_msg_send_() variant.
193 - Impacted functions:
194 gras_cb_register, gras_cb_unregister, gras_msg_send, gras_msg_wait,
195 gras_msg_rpccall, gras_msg_rpc_async_call, gras_msg_wait_ext
196 * The callbacks are now expected to return 0 when everything went well
197 (just like the main() function)
199 GRAS new features and improvements:
200 * New module mecanism where user code can use per process globals [Mt]
201 This is similar to gras_userdata_*() functions, but for libraries. It
202 factorize some code developped over and over in the examples and AMOK.
203 It has still to be documented and used (only amok/peermanagement is
205 * Fix a vicious bug in the TCP buffering mecanism which leaded to message
206 loss when they were small enough to fit into the buffer and sent quickly
207 enough so that they can all get received in one shoot.
208 * gras_datadesc_by_name and gras_msgtype_by_name: now raise an exception
209 if not found. Use the *_or_null() variant for the old semantic.
210 * In gras_msg_handle, do not discard messages without callback.
211 They are probably messages to be explicitly awaited later (ie, proofs of
212 mis-synchronization in userland since they are sent before being awaited)
214 * gras_socket_meas_send/recv: semantic changed!
215 The numerical arguments used to be (1) the total amount of data to send
216 and (2) msg_size. This was changed to (1) msg_size and (2) amount of
217 messages. This was need for the fool willing to send more than MAXINT
218 bytes on quite fat pipes.
221 * Do really rename the hostmanagement module to peermanagement. [Mt]
222 Ie, rename functions from amok_hm_* to amok_pm_*. This breaks the API,
223 but this is rather new and this was documented in the module
224 documentation (poor excuses, I admit)
225 * Bandwidth measurement semantic changed! This follows the changes to
226 gras_socket_meas_send/recv explained above.
229 * A sequential mode has been added to the workstations. When a workstation
230 is in sequential mode, it can execute only one task, and the other tasks
231 are waiting in a FIFO. [Christophe Thiery]
234 * The KCCFLN05 workstation model now handles parallel tasks. It is the
235 model for SIMDAG. [Christophe Thiery]
236 * Bug fix in the maxmin solver: Some values were close to 0 instead of
237 equal to 0, which caused some bad behaviors in
238 saturated_constraint_set_update. I now use a threshold mechanism like in
242 * When running manually src/testall, you select specific units [Mt]
243 testall is the result of our cunit mecanism, and should replace all
244 the scripty thingy around since bash don't run easily on billware.
246 * A mallocator system has been added. [Christophe Thiery]
247 Mallocators allow you to recycle your unused objects instead of freeing them
248 and allocating new ones.
250 Documentation update:
251 * FAQ reworking + New FAQs:

254 - "Cross-compiling a Windows DLL of SimGrid from Linux" [Mt]

288 There was a stack corruption somewhere, visible only when optimizing
289 with these versions. [Vince]
292 * This is a NEW module! SimDAG (SD for short) is a revival of the old SG
293 module that enabled to play with Directed Acyclic Graphs. It is built
294 directly on top of SURF and provides an API rather close to the old
295 SG. Some old codes using SG are currently under rewrite to check that
296 all needful functions are provided. [Christophe Thiery]
299 * Complete rewrite of the KCCFLN05 workstation model. It is now an
300 extension of the classical CLM03 model that gracefully handles
301 failures. This is now the default model for MSG and GRAS. It doesn't
302 handle parallel tasks yet though. [AL]
303 * Bug fix: Weights were not correctly set in the network part.
304 WARNING: This may have resulted in incorrect results with simulations
305 where there are more than one flow on a given link. [AL]
308 * After a (long ?) discussion on simgrid-devel, we have decided that the
309 convention we had on units was stupid. That is why it has been decided
310 to move from (MBits, MFlops, seconds) to (Bits, Flops, seconds).
311 WARNING : This means that all previous platform files will not work as
312 such with this version! A warning is issued to ask users to update
314 A conversion script can be found in the contrib module of the CVS, under
315 the name contrib/platform_generation/surfxml_update.pl [MQ]
318 * Bug fix: Processes were started in reverse order, wrt deployment file.
319 WARNING: if your code relies on this bug, please fix it. [AL]
320 * Bug fix: Add a test in MSG_task_execute to stop whenever a task is
321 being executed on two different locations. [AL]
322 * Bug fix: Failures are now better supported thanks to Derrick's tests
323 (there was many failure situations I hadn't thought of and that weren't
324 correctly handled). [AL]
325 * New function: MSG_host_is_avail indicates you whether a given m_host_t
329 * New! a real RPC mecanism, as it ought to be since too long. [MQ]
330 Exception occurring on server-side are propagated back to client (!).
332 API CHANGE: the callback changed their prototype. Change:
333 int my_handler(gras_socket_t expeditor, void *payload_data) {
335 int my_handler(gras_msg_cb_ctx_t ctx , void *payload_data) {
336 gras_socket_t expeditor=gras_msg_cb_ctx_from(ctx);
338 * New! function: gras_msg_handleall to deal with all messages arriving
339 within a given period.
340 * New! function: gras_socket_server_range to get a server socket in a
341 range of port numbers (ease to avoid port number conflicts) [MQ]
342 * New! gras processes display their backtrace when they get a SIGUSR1
343 or when Ctrl-C is pressed. Use Ctrl-C Ctrl-C to exit.
344 Sweet to debug RL processes [MQ]
348 - Do not force experiment sizes to be expressed in kb, or it becomes
349 impossible to measure the latency this way (needs one byte-long tests)
350 WARNING: this changes the amok_bw_* function semantic. [MQ]
351 - Implements the link saturation stuff. [MQ]
352 * Peer management module:
353 New! module factorizing code that we wrote over and over [MQ].
356 * New module: cunit (my jUnit implementation in ansi C) [MQ]
357 - Test units are placed directly into the library code, they get extracted
358 automatically and placed into the src/testall binary.
359 - Convert most of the XBT tests to this system.
360 * New functions: xbt_dynar_getfirst_as() and xbt_dynar_getlast_as() [MQ]
361 * XML parsing: rewrote parts of flexml to enable multiple xml parsers to
362 live in the same C code. This required to change a little bit the API
363 of surfxml parsing but shouldn't be an issue for end-users. [AL]
364 * New module: sparse graph structure with basic algorithms (this is work
365 in progress and the API is not considered to be frozen yet). [AL]
366 * Display more information on backtraces: source line & function names are
367 now displayed just like valgrind does (rely on addr2line tool) [MQ]
368 * New function: xbt_backtrace_display(). Sweet while debuging [MQ]
369 * Reworked a little bit some #include statements to load only required
370 headers. Some user code that relied on SimGrid to include stdlib or
371 stdio may need to include it by themselves. [AL]
372 * Fixed xbt/log.h. A missing SG_BEGIN_DECL prevented compilation with
374 * Renamed xbt_host_t into xbt_peer_t since it betterly describes what I
375 meant. This breaks the API of AMOK and of xbt/config. Sorry about this,
376 but I guess that almost nobody used those parts. [MQ]

402 and why they come from when they are not catched in time [AL, MQ]
405 * Bugfix: Do repport the error when two non-connected hosts try to
406 exchange data (Thanks to Flavien for stumbling into this one) [AL]
409 * Add additionnal checkings on communications. Assert that two
410 communicating hosts are connected by a set of links... [AL]
413 * Add additionnal checkings on channel values in communication [AL]
414 * New: MSG_task_get_source to see on which host a task was generated [HC]
415 * New: int MSG_task_probe_from_host(int channel, m_host_t host): returns
416 the number of tasks waiting to be received on channel and sent
418 * New: MSG_error_t MSG_task_get_from_host(m_task_t * task, int channel, m_host_t host);
419 waits for the first task coming from a given host.. [AL]
421 GRAS new functionnalities: [MQ]
422 * Enhance the parsing macro to allow the size of multidimentional objects
423 to be given thru annotations.
424 * New example (and documentation): Matrix Multiplication a la RPC
425 (as when I was young!) and fix a bunch of bugs found on the way.
427 GRAS performance improvements: [MQ]
429 * Reduce the amount of cbps creation/destruction by making it static to
430 datadesc_send/recv() and using a (newly created) cbps_reset (based on
433 * Change libdata to a set so that we can search for stuff by ID (and thus
434 reduce the insane amount of dict lookups)
437 * Actually implement gras_datadesc_copy() so that we don't have to mimick
438 RL communication on top of SG since it's so uneffective.
439 It may also be used for inter-thread communication in RL, one day.
440 * Use gras_datadesc_copy() to exchange messages on top of SG
442 - improve message exchange performance on top of SG
443 - deprecate transport_plugin_sg.c:gras_trp_sg_chunk_send() & recv()
444 * Don't exchange on the network the size of the used part of buffer,
445 instead, specify the possible buffer size to read().
447 - reduces the amount of read/write calls (one pair per exchange)
448 - reduces the amount of exchanged data (the size)
449 - allows to retrieve all arrived data on receiver side, if we don't need
450 it right now (subsequent read will peek the buffer)
451 - allows the receiver to proceed with the begining of the stream before
452 everything is arrived
453 - make it possible to build an iov transport (using readv/writev)
455 - take care of the data with non-stable storage (like stacked data),
457 * If possible, TCP send uses vector I/O (when writev() is here)
458 - Don't use it for receive since we send data sizes and data on the
459 same stream, so we wouldn't be able to chain large amount of chunks
460 before having to flush the stuff to read the size.
461 * Rework the transport plugin mecanism to simplify it and reduce the
462 amount of pointer dereferencement when searching for the right function
465 * I guess that now, we do almost as few system calls as possible while
466 doing as few data copy as possible.
468 To improve it further, we could try to send all the sizes first and then
469 all the data (to use iov on receiving size), but it's only a partial
470 solution: when you have 2 dimensional data, the sizes of the second
471 dimension is data of the first dimension, so you need 3 streams.
473 I'm not sure the potential performance gains justify the coding burden.

491 * New! Exception handling with setjmp or such (code from OSSP ex) [MQ]
492 This deprecates the xbt_error_t mecanisms.
493 It modifies (simplifies) all XBT and GRAS API.
494 MSG API keeps unchanged (exceptions raised by XBT are catched from

500 * New! Add automatically a loopback interface (in the default
501 network model) if none was precised.
504 * Bugfix: MSG_process_resume now works with the current running process.
506 * New! Add MSG_parallel_task_create and MSG_parallel_task_execute. [AL]
507 * Modification of MSG_task_get_compute_duration. Once a task has been

509 * New! Add double MSG_task_get_remaining_computation(m_task_t task) and
510 MSG_error_t MSG_task_cancel(m_task_t task). Add a state
511 (MSG_TASK_CANCELLED) to MSG_error_t corresponding to the cancelation
512 of a m_task. For now, MSG_task_cancel only works with computation
514 * New! Add double MSG_get_host_speed(m_host_t h) that returns the speed
515 of the processor (in Mflop/s) regardless of the current load on the
517 * API Change: use proper naming convention for MSG_getClock and
518 MSG_process_isSuspended: MSG_get_clock and MSG_process_is_suspended.
520 * New! Add void MSG_task_set_priority(m_task_t task, double priority).
521 This function changes the priority of a computation task. This priority
522 doesn't affect the transfer rate. A priority of 2 will make a task
523 receive two times more cpu power than the other ones. This function
524 has been added to suit the needs of Nguyen The Loc and hasn't been that

557 * simple/static token-ring example. [Alexandre Colucci and MQ]
558 * Use MSG_channel_select_from() and remove the *slow* hack we had to put
562 * Differentiate the types "char[22]" and "unsigned char[22]" in automatic
563 type parsing. "short" and "long" modifiers were also ignored; other
564 modifier (such as reference level) are still ignored. [MQ]
565 * Embeed the buffer size within the buffer itself on SG. [MQ]
566 That way, send() are atomic and cannot get intermixed anymore (at least
567 the ones which are less than 100k; bigger messages still have the issue)
568 * Array size pushed by the field, not by the field type (or each
569 and every long int will push stuff to the cbps) [MQ]
570 * use select() to sleep since it allows to portably sleep less than one
573 GRAS (minor cleanups)
574 * <project>.Makefile.local (generated from gras_stub_generator) |MQ]:
577 * Type Callbacks now receive the gras_datadesc_type_t they work on as argument.
578 * type category 'ignored' killed as it was never used and were difficult
580 * whether a type can cycle or not is now a flag, leaving room for more
581 flags (as "ignored", if we feel the need one day ;)
582 * Rename raw sockets to measurement sockets since "raw" has another
583 meaning in networking community.
586 * Advanced Metacomputing Overlay Kit introduction. It is based over GRAS
587 and offers features not belonging to GRAS but that most applications
588 need. One day, it may be a set of plugins loadable at runtime.
589 * New module: bandwidth

594 SimGrid (2.94) unstable; urgency=low
596 The first beta release of SimGrid 3 !
600 * Update the main page and the FAQ. Adding references to gforge.
603 * Add a gras_os_getpid function.
606 * Add MSG_task_get_compute_duration() and MSG_task_get_data_size()
607 * Extend the logs so that they also print PID, hostname, date, ... if
609 * Convert the MSG example to the use of xbt_logs instead of PRINT_MESSAGE,
610 and kill the old version which were in testsuite/
611 * Rewrite tools/MSG_visualization/colorize.pl for using with logs instead
615 * Add xbt_os_time(). As the rest of xbt/portability, this is not public
616 for users. Instead, each programming environment (GRAS, MSG,...) use it
617 when needed to provide such a feature to users.
618 Don't shortcut the mecanism or you will also shortcut the virtualization
619 you need on the simulator.
623 * Cleanups in configury with regard to compile optimization/warning flags.
624 Also add -fno-loop-optimize to any powerpc since it's the optimization
625 killing gcc (< 3.4.0).
626 * Doxygen cleanups: move MSG examples, kill the second Doxygen phase
627 needed by MSG examples complications
628 * Borrow configury beautifications from PHP
631 * Bugfix: XBT_LOG_NEW_DEFAULT_CATEGORY now compiles without compiler
632 warning (thanks loris for stumbling into this one).
633 * Bugfix: stop loading private headers (gras_config.h) from the public
637 * Change SIMGRID_INSTALL_PATH to GRAS_ROOT in Makefiles generated for user.
638 * Rename gras_get_my_fqdn to gras_os_myname and implement it in the simulator
639 RL would imply a DNS resolver, which is *hard* to do in a portable way
640 (and therefore delayed).
641 * Implement a real timer mecanism and use it in timing macros. This allows
642 to avoid rounding errors and get a 0.000005 sec precision in timing
643 macros. While I was at it, various cleanups:
644 - allow to declare more than one timed section per file (fix a stupid bug)
645 - move some private declaration to the right place
646 - merge conditional execution and timing macros into emulation module
647 - document the module
648 - make sure the module cleanups its mess on gras_exit
649 * Documentation improvements:
650 - (new) how to compile applications using GRAS
651 - (new) emulation support (timing macros)

655 SimGrid (2.93) unstable; urgency=low
657 Alpha 4 on the path to SimGrid 3 (aka the "neuf-trois" version)
660 - Use Paje properly where used. Still to be sanitized properly.
661 - Portability fix: Add an implementation of the contexts using pthread
665 - Add xbt_procname(): returns the name of the current process.
666 Use it to show the current process's name in all logging.
668 - fix detection of older flex version and the reaction, since we do
669 depend on modern ones (we use lex_destroy)
670 - Better separation of SG and RL in the libs: remove all simulation code
671 from libgras. As a result, this lib is now only 200k when stripped.
672 Some of the xbt modules may also be duplicated (two sets and such) and
673 should be cleaned/killed before SG3.
674 - Insist on using xlC on AIX because of weird problems involving gcc there.
675 - Cleanup the make remote stuff. This is now done by scripts
676 tools/graspe-{master,slave} (GRAS Platform Expender). This is still
677 mainly for our private use, but we're working on changing them to user
680 - Bugfix: flush the socket on close only if there is some *output*.
681 - Bugfix: flush idempotent when there's nothing to send (don't send size=0)
683 - Add MSG_task_get_name. The task names are mainly for debugging purpose,

694 - New! First try of benchmarking macros.
695 - New! First try so that gras_stub_generator generate deployment and
696 remote compilation helpers.
698 - Bugfix: Initialization fix in msg_test.
702 - Bugfix: applied patch to lexer so that it doesn't need a huge heap.
704 - Bugfix: let dicts work with NULL content (_foreach didn't) and cleanups
706 - API Change: gras_os_sleep to take the amount of seconds as a double.
707 Accepting an int was error prone since it was the only location where
708 seconds were coded as such. It leaded to damn rounding errors.
709 - Bugfix: Hard to belive that timers ever worked before this.

722 through the function MSG_paje_output.
723 - New! Introducing two new functions MSG_process_kill() and MSG_process_killall().
724 - It is possible to bound the rate of a communication in MSG with
725 MSG_task_put_bounded() (was already in the previous version but I had forgotten
726 to write it in the changelog).
727 - Bug fix to let GRAS run on top of MSG until we move it directly on top
732 - Various cleanups to the autotools stuff
733 - Begin to move Gras examples to examples/gras/
734 - Let make distcheck work again (yeah!)
736 - documentation overhauled using doxygen.
737 gtk-doc-tools is dead in SimGrid now.
738 - Automatically extract all existing logging categories, and add the list
739 to the documentation (long standing one, to say the less)
741 - Cleanup the known architecture table. Reorder the entries to group what
742 should be, and use a more consistent naming scheme.
743 (some of the test dataset are still to be regenerated)
744 - New! Allow library to register globals on each process just as userdata
746 This is implemented using a xbt_dict and not a xbt_set, so we loose the
747 lookup time (for now).
748 Use it in msg and trp.
749 This cleans a lot the internals and helps enforcing privacy of the
750 headers between the gras components.
751 - New! Add a timer mechanism, not unlike cron(8) and at(1).
752 - Bugfix: gras_os_time was delirious in RL.
753 - Bugfix: gras_trp_select/RL don't run into the wall when asked to select
755 - Reenable GRAS now that it works.

759 SimGrid (2.90) unstable; urgency=low
761 Alpha 1 on the path to SimGrid 3
763 * It is a long time since the last release of SimGrid. I'm sorry about
764 that but as I had told you, I was rewriting a lot of things. I apologize
765 to those who had been reporting bugs to me and that I had not answered.
766 If your bug is still in the new version, please tell me. Here is a
767 summary of the main changes.
769 * REVOLUTION 1: The SimGrid project has merged with the GRAS project
770 lead by Martin Quinson. As a consequence SimGrid gains a lot in
771 portability, speed, and a lot more but you'll figure it out later.
772 SimGrid now comprises 3 different projects : MSG, GRAS and SMPI.
773 I wanted to release the new MSG as soon as possible and I have
774 broken GRAS, which is the reason why, for now, only MSG is fully
775 functional. A laconic description of these projects is available
776 in the documentation.
778 * REVOLUTION 2: I have removed SG and I am now using a new simulation
779 kernel optimized for our needs (called SURF but only the developers
780 should use it). Hence, MSG is now roughly 30 times faster and I think
781 that by rewriting a little bit MSG, I could event speed it up a little
782 bit more. Beside the gain in speed, it is also much easier to encode a
783 new platform model with SURF than it was with SG. More to come...
785 * REVOLUTION 3: I have tried to change a little as possible the API of
786 MSG but a few things really had to disappear. The main differences
787 with the previous version are :
788 1) no more m_links_t and the corresponding functions. Platforms are
789 directly read from a XML description and cannot be hard-coded
790 anymore. The same format is used for application deployment
791 description. The new format is described in the documentation.
792 Have a look in tools/platform_generation. There is a tiny script
793 that converts from the old platform format to the new one. Concerning
794 the application deployment format, parsing the old one is tricky.
795 I think most of you should however be able to convert your files. If
796 it is really an issue, I can write a C code that does the conversion.
798 2) the toolbox tbx does not exist anymore. We now have a library
799 with much more data-structures but without the hash-tables (we have
800 dictionaries that are much faster).

804 *****************************************************************************
805 * Follows the old GRAS changelog. It does not follow the same syntax, but I *
806 * don't feel like converting the oldies. (Mt) *
807 *****************************************************************************
810 Version 2.90: "the long awaited one"
811 - Finished rewriting and debugging MSG. Rewrote the documentation.
812 - disable GRAS for now since it needs to be ported to the newest SG
815 - Finish the port to windows (using mingw32 for cross-compile)
818 - Main loop and datastructures of SURF. A cpu resource object is
819 functional. Surf can thus be used to create cpu's with variable
820 performance on which you can execute some actions.
822 2004-11-15 Martin Quinson
823 - Port to ARM. Simply added the alignment and size descriptions. Should
824 work, but the ARM machines are so slow that I didn't had the opportunity
825 to 'make check' over there yet.
827 2004-11-15 Arnaud Legrand
828 - Trace manager now written. It uses a heap structure and is therefore
829 expected to be efficient. It may however be speeded up (particularly
830 when many events occur at the same date) by using red and black
831 trees. One day maybe...
832 - Max-min linear system solver written. It uses a sparse matrix
833 structure taking advantage of its expected use. Most operations are
834 O(1) and free/calloc are called as few as possible. The computation of
835 the minimum could however be improved by using a red and black tree
838 2004-11-03 Arnaud Legrand
839 - Rename every gras_* function that was in xbt/ to its xbt_
841 - Add a heap and a doubly-linked list to xbt
842 - Added a dichotomy to the dictionaries. make check works as well before
843 so I assume that the patch is correct. I do not know however if things
844 run effectively faster than before now. :)
846 Inclusion of the SimGrid tree in the GRAS one. The archive is renamed to
847 SimGrid, and the version number is bumped to 2.x
849 2004-10-29 Martin Quinson
850 - Introduction of the remote errors.
851 They are the result of a RMI/RPC on the remote machine.
852 ErrCodes being scalar values, you can't get the host on which those
853 errors did happen. Extending the error mechanism as in Gnome is possible.
854 No idea yet whether it is a good idea.
856 2004-10-28 Martin Quinson
857 - Interface revolution: the Starred Structure Eradication.
858 I used to do typedef struct {} toto_t; and then handle *toto_t.
859 Arnaud (and Oli) didn't like it, and I surrendered. Now, you have:
860 - ???_t is a valid type (builded with typedef)
861 - s_toto_t is a structure (access to fields with .)
862 - s_toto is a structure needing 'struct' keyword to be used
863 - e_toto_t is an enum
864 - toto_t is an 'object' (struct*)
866 typedef struct s_toto {} s_toto_t, *toto_t;
867 typedef enum {} e_toto_t;
868 Moreover, only toto_t (and e_toto_t) are public. The rest (mainly
869 s_toto_t) is private.
871 - While I was at it, all gras_<obj>_free() functions want a gras_<obj>_t*
872 so that it can set the variable to NULL. It was so for dicts and sets,
873 it changed for dynars.
875 - Fix a bunch of memleaks in dict_remove
876 - Fix a bug in sg/server_socket opening: it failed all the time.
878 2004-10-07 Martin Quinson
879 - Speed up dynar lookup operation a bit.
881 gras_dynar_get is dead.
883 Now, you can choose between gras_dynar_get_cpy (the old gras_dynar_get
884 but should be avoided for efficiency reasons) and gras_dynar_get_ptr
885 (which gives you the address of the stored data).
887 gras_dynar_get_as is an helpful macro which allows you to retrieve a
888 copy of the data using an affectation to do the job and not a memcpy.
890 int toto = gras_dynar_get_as(dyn,0,int); rewrites itself to
891 int toto = *(int*)gras_dynar_get_ptr(dyn,0);
893 It does not really speedup the dynar test because they are
894 setting elements all the time (and look them seldom). But the dict does
895 far more lookup than setting.
897 So, this brings the dict_crash test from ~33s to ~25s (200000 elms).
899 2004-10-05 Martin Quinson
900 - Allow to (en/dis)able the cycle detection at run time.
902 Whether we should check for cycle or not is now a property of each
903 datatype. When you think there may be some cycle, use datadesc_cycle_set.
904 datadesc_cycle_unset allow to remove this property when previously set.
906 Note that the cycle detection is off by default since it impacts the
907 performance. Watch the data you feed GRAS with ;)
909 This property is hereditary. Any element embedded in a structure having it
910 set have it set for the time of this data exchange.
912 You should set it both on sender and receiver side. If you don't set it on
913 sender side, it will enter an endless loop. If you forget on receiver
914 side, the cycles won't be recreated after communication.
916 - Header reorganization.
917 Kill gras_private.h, each submodule must load the headers it needs.
919 2004-10-04 Martin Quinson
920 - Interface revolution: do not try to survive to malloc failure.
922 Now, gras_malloc and friends call gras_abort() on failure.
923 As a conclusion, malloc_error is not a valid error anymore, and all
924 functions for which it was the only gras_error_t return value are
925 changed. They now return void, or there result directly.
926 This simplify the API a lot.
928 2004-09-29 Martin Quinson
929 - Re-enable raw sockets.
930 Created by gras_socket_{client,server}_ext;
931 Used with gras_raw_{send,recv}
934 It should allow to kill the last bits of gras first version soon.
936 This is not completely satisfactory yet (duplicate code with
937 chunk_{send,recv}; a bit out of the plugin mechanism), but it should
940 - Simplify transport plugin (internal) interface by not passing any
941 argument to _server and _client, but embedding them in the socket
944 2004-09-28 Martin Quinson
945 - Finish the port to AIX.
946 autoconf was my problem (segfault within the malloc replacement
947 function. No idea why)
949 2004-09-16 Martin Quinson
950 - Fix some size_t madness on 64bit architectures.
952 2004-09-08 Martin Quinson
953 - Reduce the number of system headers loaded, overload some more system
954 calls (such as malloc to cast the result of the system one, and work
956 - Fix and reintroduce the config support
958 2004-09-07 Martin Quinson
959 - Source code reorganization to allow Arnaud to surf all over there.
960 - Allow to document the logging categories.
961 - Remove all uppercase from logging categories and useless cleanup in names.
963 2004-08-18 Martin Quinson
964 Version 0.6.2 (protocol not changed; API changed)
965 - Interface cleanup: gras_msgtype_by_name returns the type (instead of a
966 gras_error_t), and NULL when not found. Functions expecting a msgtype
967 as argument (msg_wait; msg_send) deal with NULL argument by providing a
968 hopefully usefull message.
969 - Portability to prehistoric sparcs again
971 2004-08-17 Martin Quinson
972 Version 0.6.1 (protocol not changed; ABI not changed)
973 - prealloc some buffers to speed things up
975 2004-08-11 Martin Quinson
976 Version 0.6 (protocol not changed; ABI expended)
977 - The parsing macro can deal with the references, provided that you add
978 the relevant annotations (using GRAS_ANNOTE(size,field_name))
980 2004-08-09 Martin Quinson
981 Version 0.5 (protocol not changed; ABI changed)
982 - Allow to off turn the cycle detection code in data exchange at
983 compilation time. It should be at run time, but I'm short of time (and
984 the config stuff is still broken). That way, we keep dict out of the
985 critical path, which is good because the performance is poor:
986 - search not dichotomial yet
987 - dynar give no way to access their content and memcpy everytime
988 - In composed data description (struct, ref and so on), stop foolness of
989 keeping the subtype's ID, but store the type itself. This keeps sets out
990 of the critical path, which is good since they rely on dynar and
991 dictionnaries. The only loose of that is that we cannot detect the
992 redeclaration of a structure/union with another content (but I'm not sure
993 the code detected well this error before anyway). We still can detect
994 the redefinition discrepancy for the other types.
995 - Use a whole bunch of optimisation flags (plus -fno-strict-aliasing since
996 it breaks the code because of type-punning used all over the place).
997 This breaks on all non-gcc architectures (for now).
999 All those changes (plus the buffer of last time) allow me to gain 2 order
1000 of magnitude on cruel tests consisting of 800000 array of integers on two
1001 level of a hierarchical structure (200 secondes -> 4 secondes)
1004 - the selector of reference must now return the type it points to, not
1005 the ID of this type.
1007 2004-08-06 Martin Quinson
1008 Version 0.4 (protocol changed; ABI not changed)
1009 - Allow to pass --gras-log argument to processes in simulation mode. Really.
1010 - New debugging level: trace (under debug) to see effect of GRAS_IN/OUT
1011 - Implement a buffer transport, and use it by default (it relies on tcp in
1012 real life and on sg in simulation).
1013 That's a bit hackish since I had a new field to the structure to store
1014 its data without interfering with the subtype ones. Inheritance
1015 is tricky in C. And that's a kind of reverse inheritance with one class
1016 derivating two classes. Or maybe a game with java interfaces. Anyway,
1017 that's damn hard in C (at least).
1018 Moreover, I got tired while trying to ensure plugin separation and
1019 genericity in SG mode. MSG wants me to do weird things, so let's go for
1020 cruel hacks (temporarily of course ;).
1021 See comment in transport_private.h:71
1022 - do not include all the _interface headers in private but in the files
1023 which really need them (to cut the compilation time when they are
1026 2004-07-26 Martin Quinson
1027 Version 0.3 (protocol not changed; ABI changed)
1028 - Major overhault of the datadesc interface to simplify it:
1029 - shorted the function names:
1030 s/gras_datadesc_declare_struct/gras_datadesc_struct/ and so on
1031 - add a trivial way to push/pop integers into the cbps without malloc.
1032 This allows to make really generic sub_type description, which simply
1033 pop their size of the stack.
1034 - add a function gras_datadesc_ref_pop_arr() which does what users want
1035 most of the time: Declare a dynamic array (which pops its size of the
1036 stack) and declare a reference to it. Poor name, but anyway.
1037 - kill the post-send callback, add a post-receive one
1039 2004-07-23 Martin Quinson
1040 Version 0.2 (protocol changed; ABI changed)
1041 - add some testing for cpbs in the test cases, and fix some more bugs.
1042 This invalidate again the little64 data file, since I cannot regenerate
1044 - remove an awfull optimization in the logging stuff, allowing me to:
1045 - understand it again
1046 - learn gcc how to check that the argument match the provided format
1047 - fix all errors revealed by gcc after that
1048 - internal keys of dict are not \0 terminated. Deal with it properly in
1049 loggings instead of segfaulting when the user want to see the logs :-/
1051 2004-07-22 Martin Quinson
1052 - Fix some stupid bug preventing cbps (callback postit) from working
1054 2004-07-21 Martin Quinson
1055 - Some documentation cleanups
1056 - remove the useless last argument of msgtype_declare
1057 - rename the Virtu functions to fit into the 'os' namespace
1058 - move headers src/include -> src/include/gras/ and stop fooling with
1059 gras -> . symbolic link
1060 - make distcheck is now successful
1062 2004-07-19 Martin Quinson
1064 - Build shared library also
1065 - Install html doc to the right location

1067 - build tests only on make check
1069 2004-07-13 Martin Quinson
1071 - No major issue in previous version => change versionning schema
1072 - Re-enable little64 convertion test now that Abdou kindly regenerated the
1073 corresponding dataset.
1075 2004-07-11 Martin Quinson
1077 - Get it working with any kind of structure (we can compute the padding
1078 bytes remotely for all the architectures I have access to)
1079 - Implement the structure parsing macro (still not quite robust/complete)
1080 - Improvement to the remote testing toysuite
1082 2004-07-10 Martin Quinson
1083 [autoconf mechanism]
1084 - get ride of a bunch of deprecated macros
1085 - actually run the test for two-compliment, not only compile it :-/
1086 - test whether the structures get packed (and bail out if yes. Damn.
1087 Alignment is a serious matter)
1088 - test whether the structures get compacted (but respecting the alignment
1089 constraints of each types)
1090 - test whether the array fields of structures can straddle alignment boundaries
1092 - Damnit, double are bigger than float (typo in creation of 'double' datadesc)
1093 (took me 2 hours to find that bug, looking at the wrong place)
1094 - Add gras_datadesc_declare_{union,struct}_close(). They must be used
1095 before sending/receiving and are used to compute the offsets of fields
1096 - Given that padding size depend even on compiler options, keep track of
1097 alignment and aligned_size only for the current architecture. Not a big
1098 deal since we send structure fields one after the other (seems
1100 - Add the datastructure used for IEEE paper by the PBIO guys to the test
1101 program, let it work on linux/gcc/little32. portability todo.
1103 2004-07-08 Martin Quinson
1104 - import and improve remote compilation support from FAST
1105 - make sure make check works on half a dozen of machines out there
1107 2004-07-07 Martin Quinson
1108 Let's say it's version 0.0.3 ;)
1109 - Implement conversions (yuhu!)
1110 - Let it work on solaris (beside conversion, of course)
1111 - Stupid me, using rand() to generate the conversion datatests in not wise.
1113 2004-07-06 Martin Quinson
1114 - Let make dist work, since I'm gonna need it to compile on remote hosts
1115 - Let Tests/datadesc_usage write the architecture on which the file was
1116 generated as first byte.
1117 - Add PowerPC (being also IRIX64), SPARC (also power4) and ALPHA
1118 architecture descriptions.
1119 - Add datadesc_usage.{i386,ppc,sparc} files being the result of execution
1120 on those architectures.
1121 - Optimization: send/recv array of scalar in one shoot
1123 2004-07-05 Martin Quinson
1124 - YEAH! GRAS/SG and GRAS/RL are both able to run the ping example !
1126 - Plug a whole bunch of memleaks
1127 - each process now have to call gras_{init,exit}. One day, their log
1128 settings will be separated
1129 - Continue the code factorisation between SG, RL and common in Transport.
1131 2004-07-04 Martin Quinson
1133 - Redistribution between SG and RL.
1134 We wanna have to accept in SG, so move accepted related parts of RL in
1135 the common part. (more precisely, the dynar of all known sockets is no
1136 more a static in transport.c, but part of the process_data)
1138 [gras_stub_generator]
1139 - Bug fix: Do call gras_process_init from gras_init (wasnt called in RL).
1141 2004-07-03 Martin Quinson
1142 - Create a new log channel tbx containing dict, set, log, dynar (to shut
1143 them all up in one shot)
1145 - Fix the ugly case of reference to dynamic array.
1146 - New (semi-public) function gras_datadesc_size to allow the messaging
1147 layer to malloc the needed space for the buffer.
1149 - gras_socket_close now expect the socket to close (and not its address to
1150 put NULL in it after it). This is because the socket passed to handlers
1151 is one of their argument (=> not writable).
1153 - propagate the interface cleanup from last week in datadesc, ie remove a
1154 superfluous level of indirection. User pass adress of variable
1155 containing data (both when sending and receiving), and not of a variable
1156 being a pointer to the data. Let's say that I like it better ;)
1157 The price for that is constructs like "int msg=*(int*)payload" in
1158 handlers, but it's a fine price, IMHO.
1160 - Let it work in RL (yuhu)
1162 2004-06-21 Martin Quinson
1164 - porting SG plugin and SG select to new standards (works almost).
1165 - plug memleaks and fix bugs around.
1168 - cleanup the prototype of data recv and force users to specify when they
1169 want to handle references to objects. Test case working even for cycles.
1170 - plug memleaks. Valgrind is perfectly ok with this.
1172 2004-06-12 Martin Quinson
1174 - cleanup the separation between plugin and main code in plugin creation
1176 2004-06-11 Martin Quinson
1178 - Reput hook for raw sockets, needed for BW experiments
1179 - kill a few lines of dead code
1180 [Data description] Interface cleanup
1181 - gras_datadesc_by_name returns the searched type or NULL.
1182 That way, no variable is needed to use a type desc once, which makes
1184 - gras_datadesc_declare_[struct|union]_append_name is removed. The last
1185 two parameters were strings (field name, type name), leading to
1187 [Dicos] Interface cleanup
1188 - gras_dico_retrieve -> gras_dico_get ; gras_dico_insert -> gras_dico_set
1189 This is consistant with the dynar API.
1191 2004-04-21 Martin Quinson
1193 - Porting to new standards.
1195 - interface cleanup.
1196 There is no bag anymore, no need to take extra provision to mask the
1197 pointers behind "ID".
1198 Better splitup of functions between files create/exchange/convert.
1199 This is still a bit artificial since convert and receive are so
1200 interleaved, but anyway.
1202 - add a queued message list to procdata (the ones not matching criteria
1204 - factorize some more code between SG and RL wrt procdata
1206 - use gras_exit in example to track memleaks
1207 - get rid of gs_example now that GS is properly integrated into gras
1208 - update run_test to integrate the lastest tests (datadesc)
1210 - rename WARNINGn macros to WARNn since it prooved error-prone
1212 2004-04-19 Martin Quinson
1214 - register init/exit functions within gras module mechanism
1215 - send/receive function.
1216 Convertion is not implemented, but short-cutted if not needed.
1217 struct/array elements are sent one by one (instead of block-wise), but
1218 nobody really cares (yet). Get a prototype before optimizing.
1219 - tests (using a file socket) for DD send/receive on:
1220 - base types: int, float
1221 - array: fixed size, string (ie ref to dynamic string)
1222 - structure: homogeneous, heterogeneous
1223 - chained list, graph with cycle
1224 Believe it or not, valgrind is not too unhappy with the results. The
1225 cycle happily segfaults, but the others are ok. And I'm sick of pointers
1229 - Bugfix when using a filename explicitely (instead of '-')
1231 2004-04-09 Martin Quinson
1233 - factorize more code between RL and SG in socket creation
1234 - Complete the implementation and tests of:
1236 o file (only in RL, and mainly for debugging)
1238 I lost 3 days to design a portable address resolver, and then decided
1239 that the prototype mainly have to run on my box.
1240 Addressing portability too early may be like optimizing too early :-/
1242 - use gras_init in the Tests instead of the crappy parse_log_opt
1243 (the latter function is removed)
1244 [Conditional execution]
1245 - New functions: gras_if_RL/gras_if_SG (basic support for this)
1246 [Code reorganisation]
1247 - Get rid of libgrasutils.a since it makes more trouble than it solves.
1248 Build examples against the RL library, since there is no way to disable
1249 its creation for now.
1251 For information, the beginning of coding on GRAS was back in june
1252 2003. I guess that every line has been rewritten at least twice since
