9 - Was dupplicated in network.c and workstation_LV07.c
10 - We may want to implement other ways of storing that info

15 * Factorize the set of resources within common_public;
16 + change model->common_model->resource_name()
17 into surf_model_resource_by_name(model)

41 * Implement a --cfg-help to show existing configuration variables
42 * Build chain do not require doxygen in maintainer mode
45 * fix a bug on struct sizeof computation, which prevented the
46 exchange of arrays of structs in some conditions
47 - added a regression test about this in datadesc_usage
48 * Allow the exchange of 0-long dynamic vectors.
49 - for that, use -1 as indicator of dynamic size instead of 0
50 - This implied to change any size from unsigned long to long,
51 reducing a bit communication abilities, but I guess that with
52 64bits being quite common, this is more than enough.
53 - This also induce a protocol change, thus bumping network protocol
54 version from 0 to 1 (if we have external users, we have to get
55 clean on that point too ;)
56 - added two regression tests about this in datadesc_usage
57 * Be more verbose when propagating local exceptions
59 * Display the status of simulated processes when receiving SIGINT in
63 * Allow to control the simulation from a trace file.
64 New functions MSG_action_register() and MSG_action_trace_run()
65 The first one allows to associate a function execution to each
66 kind of action while the second one parses a trace file and
67 triggers the corresponding actions within the system.
68 For now, only a toy example is provided in examples/msg/actions
69 * Add an exemple of process migration in examples/msg/migration
70 * Fix a bug in task exchange which broke MSG_task_get_sender()
71 Add a teshsuite regression test for that.
72 [Bug: if MSG_task_get_sender() is called after sender exit,
74 * Fix a bug which prevented suspend/resume to work properly
75 * Display the status of simulated processes when receiving SIGINT
76 This fixes a regression of v3.3. due to the introduction of SIMIX
77 * Bug fixing in failure management:
78 - trace could not start by a failure at time 0
79 - failure during communications were not working
82 * Add SIMIX_process_set_name() to change the name of the current
83 process in the log messages.
84 * Store smx_hosts in a dict since we only retrieve them by name
85 * Move the configuration infrastructure to surf
88 * Move the configuration infrastructure to surf
91 * Massive internal cleanups:
92 - Store internal structures on processes instead of hosts (allows
93 to have more than one process per host, in addition of being more
95 - Cleanup the initialization/finalization process
96 - Kill a whole bunch of unneeded synchronization:
97 processes run in exclusive manner within the simulator
98 - Move queues from global tables to process data fields
100 - now accept -platform and -hostfile arguments
101 - Pass the right rank value to processes according to the hostfile
102 * Compile the examples by default, and use them as regression tests
103 * Implement MPI_Wtime()
104 * Change the reference speed to a command line option
107 * TCP_gamma can now be specified as command line option using
108 --cfg=TCP_gamma:10000000.0
109 * Change the --surf-path cmd line option into --cfg=path:
112 * Also include strbuff from xbt.h public header
113 * xbt_ex_display(): do not free the exception after displaying
114 This allows to do more with the given exception afterward.
115 Users should call xbt_ex_free() themselves.
119 Portability report of this version:
120 * Main portability targets:
121 - Linux(debian)/x86/context
122 - Linux(debian)/x86/pthreads
123 - Linux(debian)/amd64/context
124 - Linux(debian)/amd64/pthreads
125 These targets fail about 1/10 of times on gras/pmm, but we believe
126 that this is because of the test, not because of simgrid.
127 amok/saturate_sg fails even more rarely, and the test may not be
130 - Mac OSX Leopard/x86/context
131 The test suite still spits tons of errors because some obscure
132 force prevents us from removing the temporary directories
133 arguing that they still contain some metadata I've never heard of.
134 Smpi fails because seq is not installed.
135 Everything seems to work properly beside of that.
138 - AIX version 5.3 (both contexts and pthread)

151 * JAVA BINDINGS for MSG (you dreamt of them? We made them)
154 * Introduce the SIMIX module: factorize code between MSG and GRAS.
157 Until now, GRAS were using MSG as an interface to SURF. It was
158 quite difficult because both interface have several differences
159 (MSG channels vs GRAS sockets were the most notable point).
161 This also opens the gate to SMPI (which should occur soon) and speed
162 up simulations by to 40% (even if it were not the main goal).
164 **************************************
165 *DO NOT MIX 3.2 RESULTS WITH 3.3 ONES* Simix may changes simulations!
166 **************************************
167 The point is that events occuring at the exact same timestamp are
168 not scheduled in the same order with the old and new version. This
169 may be enough to completely change the execution of simulations in
170 some cases. Sorry for the inconvenience.
172 * Cleanup and upgrade the XML format to push further scalability
173 issues (check http://hal.inria.fr/inria-00256883/ for more info)
175 * Improve the testing infrastructure with tesh. Now a very large part of
176 the code is tested not only by being run but also by checking that the
177 output match an expected output [Mt].
179 * Move on to FleXML v1.7 for the embeeded XML parsers. This version
180 is really less memory-demanding, which should allow you to use
181 larger files in SimGrid [AL].
183 * Inform valgrind about our contextes, so that it becomes usable
184 with the default (and more effecient) version of SimGrid
185 [contributed by Sékou Diakite, many thanks]
188 * Introduce a listener thread in charge of receiving incomming
189 messages from the network. It allows to overlap communication and
190 computation but most notably, it removes some stupid deadlocks due
191 to the fact that so far, a process could not send and receive at
192 the same time. This made most non trivial communication schema
194 * Convert the PIDs from long int to int to match the MSG ones (and
196 * New function: gras_agent_spawn() to launch a new process on
197 current host. Only working in simulation for now. [Mt]
198 * New function: gras_os_hostport() returning a constant form (ie,
199 not needing to be freed) of "gras_os_hostname():gras_os_myport()"
202 * Make the backtrace of exceptions more human readable [Mt]
203 * New module: xbt/str [Mt]
204 a ton of string utility functions (split, join, printf to a newly
205 allocated buffer, trim, etc)
206 * New module: xbt/hash [Mt]
207 SHA1 hashing algorithm (more to come if needed)
208 * New module: xbt/synchro [Mt]
209 synchronization tools (mutex and conditions) working the same way
210 in simulation and in real life (mainly useful for GRAS, but not
212 * New module: xbt/queue [Mt]
213 classical producer/consumer synchronization scheme
214 * xbt_dynar_new_sync() creates a synchronized dynar. All access
215 (using the classical functions will get serialized) [Mt]
216 * Make dictionary internal table dynamic. No need to specify its size
217 anymore; functions xbt_dict_new_ext() and xbt_dict_hashsize_set()
219 * Make sure the log channels are organized as a tree under windows
220 (because of ANSI C compatibility issue, any channel were child of
224 * Cleaned many thing in surf and fixed a few bugs [AL].
225 * Add a nice command line configuration mechanism to compose models [AL].
226 * Add a new model for parallel tasks (ptask_L07) that is less buggy than
227 the previous one (KCCFLN05). It relies on something that looks like
228 a max-min sharing mechanism but cannot be written as such. A new solver
229 was thus designed [AL].
230 * Add a new solver to lmm. Based on Lagrange optimization and
231 gradient-based descent, it enables to efficiently maximise systems s.a
233 sum f_i(x_i) s.t Ax<= b with A_{i,j}>=0 and f_i a concave function.
235 This solver enables to propose two new network models for TCP Reno and
236 TCP Vegas based on Low's work. These models still need to be fully
237 tested though [Pedro Velho].
240 * Bug fix in SD_simulate. Now the time bound given as argument is
242 * Use the new parallel task model (ptask_L07) as default.
243 * Use the SURF command line configuration mechanism.
244 * 0-size tasks (for synchronization) should now work.

252 We still experience issues on this platform, but we believe that at
255 GRAS API BREAKAGE (for simplification purpose, sorry):
256 * the gras_msgtype_by_name is not used anymore. Instead of
257 gras_msg_send(toserver, gras_msgtype_by_name("request"), &request);
258 you can write (and must)
259 gras_msg_send(toserver, "request", &request);
260 - If you still want to pass a gras_msgtype_t to the function (to cache
261 the type and avoid the lookup time), use the gras_msg_send_() variant.
262 - Impacted functions:
263 gras_cb_register, gras_cb_unregister, gras_msg_send, gras_msg_wait,
264 gras_msg_rpccall, gras_msg_rpc_async_call, gras_msg_wait_ext
265 * The callbacks are now expected to return 0 when everything went well
266 (just like the main() function)
268 GRAS new features and improvements:
269 * New module mecanism where user code can use per process globals [Mt]
270 This is similar to gras_userdata_*() functions, but for libraries. It
271 factorize some code developped over and over in the examples and AMOK.
272 It has still to be documented and used (only amok/peermanagement is
274 * Fix a vicious bug in the TCP buffering mecanism which leaded to message
275 loss when they were small enough to fit into the buffer and sent quickly
276 enough so that they can all get received in one shoot.
277 * gras_datadesc_by_name and gras_msgtype_by_name: now raise an exception
278 if not found. Use the *_or_null() variant for the old semantic.
279 * In gras_msg_handle, do not discard messages without callback.
280 They are probably messages to be explicitly awaited later (ie, proofs of
281 mis-synchronization in userland since they are sent before being awaited)
283 * gras_socket_meas_send/recv: semantic changed!
284 The numerical arguments used to be (1) the total amount of data to send
285 and (2) msg_size. This was changed to (1) msg_size and (2) amount of
286 messages. This was need for the fool willing to send more than MAXINT
287 bytes on quite fat pipes.
290 * Do really rename the hostmanagement module to peermanagement. [Mt]
291 Ie, rename functions from amok_hm_* to amok_pm_*. This breaks the API,
292 but this is rather new and this was documented in the module
293 documentation (poor excuses, I admit)
294 * Bandwidth measurement semantic changed! This follows the changes to
295 gras_socket_meas_send/recv explained above.
298 * A sequential mode has been added to the workstations. When a workstation
299 is in sequential mode, it can execute only one task, and the other tasks
300 are waiting in a FIFO. [Christophe Thiery]
303 * The KCCFLN05 workstation model now handles parallel tasks. It is the
304 model for SIMDAG. [Christophe Thiery]
305 * Bug fix in the maxmin solver: Some values were close to 0 instead of
306 equal to 0, which caused some bad behaviors in
307 saturated_constraint_set_update. I now use a threshold mechanism like in
311 * When running manually src/testall, you select specific units [Mt]
312 testall is the result of our cunit mecanism, and should replace all
313 the scripty thingy around since bash don't run easily on billware.
315 * A mallocator system has been added. [Christophe Thiery]
316 Mallocators allow you to recycle your unused objects instead of freeing them
317 and allocating new ones.
319 Documentation update:
320 * FAQ reworking + New FAQs:

357 There was a stack corruption somewhere, visible only when optimizing
358 with these versions. [Vince]
361 * This is a NEW module! SimDAG (SD for short) is a revival of the old SG
362 module that enabled to play with Directed Acyclic Graphs. It is built
363 directly on top of SURF and provides an API rather close to the old
364 SG. Some old codes using SG are currently under rewrite to check that
365 all needful functions are provided. [Christophe Thiery]
368 * Complete rewrite of the KCCFLN05 workstation model. It is now an
369 extension of the classical CLM03 model that gracefully handles
370 failures. This is now the default model for MSG and GRAS. It doesn't
371 handle parallel tasks yet though. [AL]
372 * Bug fix: Weights were not correctly set in the network part.
373 WARNING: This may have resulted in incorrect results with simulations
374 where there are more than one flow on a given link. [AL]
377 * After a (long ?) discussion on simgrid-devel, we have decided that the
378 convention we had on units was stupid. That is why it has been decided
379 to move from (MBits, MFlops, seconds) to (Bits, Flops, seconds).
380 WARNING : This means that all previous platform files will not work as
381 such with this version! A warning is issued to ask users to update
383 A conversion script can be found in the contrib module of the CVS, under
384 the name contrib/platform_generation/surfxml_update.pl [MQ]
387 * Bug fix: Processes were started in reverse order, wrt deployment file.
388 WARNING: if your code relies on this bug, please fix it. [AL]
389 * Bug fix: Add a test in MSG_task_execute to stop whenever a task is
390 being executed on two different locations. [AL]
391 * Bug fix: Failures are now better supported thanks to Derrick's tests
392 (there was many failure situations I hadn't thought of and that weren't
393 correctly handled). [AL]
394 * New function: MSG_host_is_avail indicates you whether a given m_host_t
398 * New! a real RPC mecanism, as it ought to be since too long. [MQ]
399 Exception occurring on server-side are propagated back to client (!).
401 API CHANGE: the callback changed their prototype. Change:
402 int my_handler(gras_socket_t expeditor, void *payload_data) {
404 int my_handler(gras_msg_cb_ctx_t ctx , void *payload_data) {
405 gras_socket_t expeditor=gras_msg_cb_ctx_from(ctx);
407 * New! function: gras_msg_handleall to deal with all messages arriving
408 within a given period.
409 * New! function: gras_socket_server_range to get a server socket in a
410 range of port numbers (ease to avoid port number conflicts) [MQ]
411 * New! gras processes display their backtrace when they get a SIGUSR1
412 or when Ctrl-C is pressed. Use Ctrl-C Ctrl-C to exit.
413 Sweet to debug RL processes [MQ]
417 - Do not force experiment sizes to be expressed in kb, or it becomes
418 impossible to measure the latency this way (needs one byte-long tests)
419 WARNING: this changes the amok_bw_* function semantic. [MQ]
420 - Implements the link saturation stuff. [MQ]
421 * Peer management module:
422 New! module factorizing code that we wrote over and over [MQ].
425 * New module: cunit (my jUnit implementation in ansi C) [MQ]
426 - Test units are placed directly into the library code, they get extracted
427 automatically and placed into the src/testall binary.
428 - Convert most of the XBT tests to this system.
429 * New functions: xbt_dynar_getfirst_as() and xbt_dynar_getlast_as() [MQ]
430 * XML parsing: rewrote parts of flexml to enable multiple xml parsers to
431 live in the same C code. This required to change a little bit the API
432 of surfxml parsing but shouldn't be an issue for end-users. [AL]
433 * New module: sparse graph structure with basic algorithms (this is work
434 in progress and the API is not considered to be frozen yet). [AL]
435 * Display more information on backtraces: source line & function names are
436 now displayed just like valgrind does (rely on addr2line tool) [MQ]
437 * New function: xbt_backtrace_display(). Sweet while debuging [MQ]
438 * Reworked a little bit some #include statements to load only required
439 headers. Some user code that relied on SimGrid to include stdlib or
440 stdio may need to include it by themselves. [AL]
441 * Fixed xbt/log.h. A missing SG_BEGIN_DECL prevented compilation with
443 * Renamed xbt_host_t into xbt_peer_t since it betterly describes what I
444 meant. This breaks the API of AMOK and of xbt/config. Sorry about this,
445 but I guess that almost nobody used those parts. [MQ]

488 waits for the first task coming from a given host.. [AL]
490 GRAS new functionnalities: [MQ]
491 * Enhance the parsing macro to allow the size of multidimentional objects
492 to be given thru annotations.
493 * New example (and documentation): Matrix Multiplication a la RPC
494 (as when I was young!) and fix a bunch of bugs found on the way.
496 GRAS performance improvements: [MQ]
498 * Reduce the amount of cbps creation/destruction by making it static to
499 datadesc_send/recv() and using a (newly created) cbps_reset (based on
502 * Change libdata to a set so that we can search for stuff by ID (and thus
503 reduce the insane amount of dict lookups)
506 * Actually implement gras_datadesc_copy() so that we don't have to mimick
507 RL communication on top of SG since it's so uneffective.
508 It may also be used for inter-thread communication in RL, one day.
509 * Use gras_datadesc_copy() to exchange messages on top of SG
511 - improve message exchange performance on top of SG
512 - deprecate transport_plugin_sg.c:gras_trp_sg_chunk_send() & recv()
513 * Don't exchange on the network the size of the used part of buffer,
514 instead, specify the possible buffer size to read().
516 - reduces the amount of read/write calls (one pair per exchange)
517 - reduces the amount of exchanged data (the size)
518 - allows to retrieve all arrived data on receiver side, if we don't need
519 it right now (subsequent read will peek the buffer)
520 - allows the receiver to proceed with the begining of the stream before
521 everything is arrived
522 - make it possible to build an iov transport (using readv/writev)
524 - take care of the data with non-stable storage (like stacked data),
526 * If possible, TCP send uses vector I/O (when writev() is here)
527 - Don't use it for receive since we send data sizes and data on the
528 same stream, so we wouldn't be able to chain large amount of chunks
529 before having to flush the stuff to read the size.
530 * Rework the transport plugin mecanism to simplify it and reduce the
531 amount of pointer dereferencement when searching for the right function
534 * I guess that now, we do almost as few system calls as possible while
535 doing as few data copy as possible.
537 To improve it further, we could try to send all the sizes first and then
538 all the data (to use iov on receiving size), but it's only a partial
539 solution: when you have 2 dimensional data, the sizes of the second
540 dimension is data of the first dimension, so you need 3 streams.
542 I'm not sure the potential performance gains justify the coding burden.

563 MSG API keeps unchanged (exceptions raised by XBT are catched from
564 within MSG and masked with existing error handling facilities)
567 * New! Add a FATPIPE model. [AL]
568 * New! Add a parallel task model. [AL]
569 * New! Add automatically a loopback interface (in the default
570 network model) if none was precised.
573 * Bugfix: MSG_process_resume now works with the current running process.
575 * New! Add MSG_parallel_task_create and MSG_parallel_task_execute. [AL]
576 * Modification of MSG_task_get_compute_duration. Once a task has been
577 processed, the value returned by this function is now equal to 0. [AL]
578 * New! Add double MSG_task_get_remaining_computation(m_task_t task) and
579 MSG_error_t MSG_task_cancel(m_task_t task). Add a state
580 (MSG_TASK_CANCELLED) to MSG_error_t corresponding to the cancelation
581 of a m_task. For now, MSG_task_cancel only works with computation
583 * New! Add double MSG_get_host_speed(m_host_t h) that returns the speed
584 of the processor (in Mflop/s) regardless of the current load on the
586 * API Change: use proper naming convention for MSG_getClock and
587 MSG_process_isSuspended: MSG_get_clock and MSG_process_is_suspended.
589 * New! Add void MSG_task_set_priority(m_task_t task, double priority).
590 This function changes the priority of a computation task. This priority
591 doesn't affect the transfer rate. A priority of 2 will make a task
592 receive two times more cpu power than the other ones. This function
593 has been added to suit the needs of Nguyen The Loc and hasn't been that
594 much tested yet. So if it fails, please report it and send me your code.
596 * API Change: removed all functions and types that were marked "deprecated"
597 since many months. Renamed MSG_global_init_args to MSG_global_init.

617 * Implement MSG_channel_select_from() to help GRAS now that SURF provide
618 the needed support (timeouts) [AL]
621 * Implement measurement sockets. You can now get the bandwidth between two
622 hosts thanks to AMOK (see below). [MQ]
623 * gras_datadesc_dynar() builds a dynar type descriptor, allowing to send
624 dynar over the network (yeah) [MQ]
625 * Real (even if simplistic) implementation of gras_os_myname() on RL [MQ]
626 * simple/static token-ring example. [Alexandre Colucci and MQ]
627 * Use MSG_channel_select_from() and remove the *slow* hack we had to put
631 * Differentiate the types "char[22]" and "unsigned char[22]" in automatic
632 type parsing. "short" and "long" modifiers were also ignored; other
633 modifier (such as reference level) are still ignored. [MQ]
634 * Embeed the buffer size within the buffer itself on SG. [MQ]
635 That way, send() are atomic and cannot get intermixed anymore (at least
636 the ones which are less than 100k; bigger messages still have the issue)
637 * Array size pushed by the field, not by the field type (or each
638 and every long int will push stuff to the cbps) [MQ]
639 * use select() to sleep since it allows to portably sleep less than one
642 GRAS (minor cleanups)
643 * <project>.Makefile.local (generated from gras_stub_generator) |MQ]:
646 * Type Callbacks now receive the gras_datadesc_type_t they work on as argument.
647 * type category 'ignored' killed as it was never used and were difficult
649 * whether a type can cycle or not is now a flag, leaving room for more
650 flags (as "ignored", if we feel the need one day ;)
651 * Rename raw sockets to measurement sockets since "raw" has another
652 meaning in networking community.
655 * Advanced Metacomputing Overlay Kit introduction. It is based over GRAS
656 and offers features not belonging to GRAS but that most applications
657 need. One day, it may be a set of plugins loadable at runtime.

663 SimGrid (2.94) unstable; urgency=low
665 The first beta release of SimGrid 3 !
669 * Update the main page and the FAQ. Adding references to gforge.
672 * Add a gras_os_getpid function.
675 * Add MSG_task_get_compute_duration() and MSG_task_get_data_size()
676 * Extend the logs so that they also print PID, hostname, date, ... if
678 * Convert the MSG example to the use of xbt_logs instead of PRINT_MESSAGE,
679 and kill the old version which were in testsuite/
680 * Rewrite tools/MSG_visualization/colorize.pl for using with logs instead
684 * Add xbt_os_time(). As the rest of xbt/portability, this is not public
685 for users. Instead, each programming environment (GRAS, MSG,...) use it
686 when needed to provide such a feature to users.
687 Don't shortcut the mecanism or you will also shortcut the virtualization
688 you need on the simulator.
692 * Cleanups in configury with regard to compile optimization/warning flags.
693 Also add -fno-loop-optimize to any powerpc since it's the optimization
694 killing gcc (< 3.4.0).
695 * Doxygen cleanups: move MSG examples, kill the second Doxygen phase
696 needed by MSG examples complications
697 * Borrow configury beautifications from PHP
700 * Bugfix: XBT_LOG_NEW_DEFAULT_CATEGORY now compiles without compiler
701 warning (thanks loris for stumbling into this one).
702 * Bugfix: stop loading private headers (gras_config.h) from the public
706 * Change SIMGRID_INSTALL_PATH to GRAS_ROOT in Makefiles generated for user.
707 * Rename gras_get_my_fqdn to gras_os_myname and implement it in the simulator
708 RL would imply a DNS resolver, which is *hard* to do in a portable way
709 (and therefore delayed).
710 * Implement a real timer mecanism and use it in timing macros. This allows
711 to avoid rounding errors and get a 0.000005 sec precision in timing
712 macros. While I was at it, various cleanups:
713 - allow to declare more than one timed section per file (fix a stupid bug)
714 - move some private declaration to the right place
715 - merge conditional execution and timing macros into emulation module
716 - document the module
717 - make sure the module cleanups its mess on gras_exit
718 * Documentation improvements:
719 - (new) how to compile applications using GRAS
720 - (new) emulation support (timing macros)

726 Alpha 4 on the path to SimGrid 3 (aka the "neuf-trois" version)
729 - Use Paje properly where used. Still to be sanitized properly.
730 - Portability fix: Add an implementation of the contexts using pthread
734 - Add xbt_procname(): returns the name of the current process.
735 Use it to show the current process's name in all logging.
737 - fix detection of older flex version and the reaction, since we do
738 depend on modern ones (we use lex_destroy)
739 - Better separation of SG and RL in the libs: remove all simulation code
740 from libgras. As a result, this lib is now only 200k when stripped.
741 Some of the xbt modules may also be duplicated (two sets and such) and
742 should be cleaned/killed before SG3.
743 - Insist on using xlC on AIX because of weird problems involving gcc there.
744 - Cleanup the make remote stuff. This is now done by scripts
745 tools/graspe-{master,slave} (GRAS Platform Expender). This is still
746 mainly for our private use, but we're working on changing them to user
749 - Bugfix: flush the socket on close only if there is some *output*.

828 SimGrid (2.90) unstable; urgency=low
830 Alpha 1 on the path to SimGrid 3
832 * It is a long time since the last release of SimGrid. I'm sorry about
833 that but as I had told you, I was rewriting a lot of things. I apologize
834 to those who had been reporting bugs to me and that I had not answered.
835 If your bug is still in the new version, please tell me. Here is a
836 summary of the main changes.
838 * REVOLUTION 1: The SimGrid project has merged with the GRAS project
839 lead by Martin Quinson. As a consequence SimGrid gains a lot in
840 portability, speed, and a lot more but you'll figure it out later.
841 SimGrid now comprises 3 different projects : MSG, GRAS and SMPI.
842 I wanted to release the new MSG as soon as possible and I have
843 broken GRAS, which is the reason why, for now, only MSG is fully
844 functional. A laconic description of these projects is available
845 in the documentation.
847 * REVOLUTION 2: I have removed SG and I am now using a new simulation
848 kernel optimized for our needs (called SURF but only the developers
849 should use it). Hence, MSG is now roughly 30 times faster and I think
850 that by rewriting a little bit MSG, I could event speed it up a little
851 bit more. Beside the gain in speed, it is also much easier to encode a
852 new platform model with SURF than it was with SG. More to come...
854 * REVOLUTION 3: I have tried to change a little as possible the API of
855 MSG but a few things really had to disappear. The main differences
856 with the previous version are :
857 1) no more m_links_t and the corresponding functions. Platforms are
858 directly read from a XML description and cannot be hard-coded
859 anymore. The same format is used for application deployment
860 description. The new format is described in the documentation.
861 Have a look in tools/platform_generation. There is a tiny script
862 that converts from the old platform format to the new one. Concerning
863 the application deployment format, parsing the old one is tricky.
864 I think most of you should however be able to convert your files. If
865 it is really an issue, I can write a C code that does the conversion.
867 2) the toolbox tbx does not exist anymore. We now have a library
868 with much more data-structures but without the hash-tables (we have
869 dictionaries that are much faster).
871 -- Arnaud Legrand <Arnaud.Legrand@imag.fr> Mon, 31 Jan 2005 10:45:53 -0800
873 *****************************************************************************
874 * Follows the old GRAS changelog. It does not follow the same syntax, but I *
875 * don't feel like converting the oldies. (Mt) *
876 *****************************************************************************
879 Version 2.90: "the long awaited one"
880 - Finished rewriting and debugging MSG. Rewrote the documentation.
881 - disable GRAS for now since it needs to be ported to the newest SG
884 - Finish the port to windows (using mingw32 for cross-compile)
887 - Main loop and datastructures of SURF. A cpu resource object is
888 functional. Surf can thus be used to create cpu's with variable
889 performance on which you can execute some actions.
891 2004-11-15 Martin Quinson
892 - Port to ARM. Simply added the alignment and size descriptions. Should
893 work, but the ARM machines are so slow that I didn't had the opportunity
894 to 'make check' over there yet.
896 2004-11-15 Arnaud Legrand
897 - Trace manager now written. It uses a heap structure and is therefore
898 expected to be efficient. It may however be speeded up (particularly
899 when many events occur at the same date) by using red and black
900 trees. One day maybe...
901 - Max-min linear system solver written. It uses a sparse matrix
902 structure taking advantage of its expected use. Most operations are
903 O(1) and free/calloc are called as few as possible. The computation of
904 the minimum could however be improved by using a red and black tree
907 2004-11-03 Arnaud Legrand
908 - Rename every gras_* function that was in xbt/ to its xbt_
910 - Add a heap and a doubly-linked list to xbt
911 - Added a dichotomy to the dictionaries. make check works as well before
912 so I assume that the patch is correct. I do not know however if things
913 run effectively faster than before now. :)
915 Inclusion of the SimGrid tree in the GRAS one. The archive is renamed to
916 SimGrid, and the version number is bumped to 2.x
918 2004-10-29 Martin Quinson
919 - Introduction of the remote errors.
920 They are the result of a RMI/RPC on the remote machine.
921 ErrCodes being scalar values, you can't get the host on which those
922 errors did happen. Extending the error mechanism as in Gnome is possible.
923 No idea yet whether it is a good idea.
925 2004-10-28 Martin Quinson
926 - Interface revolution: the Starred Structure Eradication.
927 I used to do typedef struct {} toto_t; and then handle *toto_t.
928 Arnaud (and Oli) didn't like it, and I surrendered. Now, you have:
929 - ???_t is a valid type (builded with typedef)
930 - s_toto_t is a structure (access to fields with .)
931 - s_toto is a structure needing 'struct' keyword to be used
932 - e_toto_t is an enum
933 - toto_t is an 'object' (struct*)
935 typedef struct s_toto {} s_toto_t, *toto_t;
936 typedef enum {} e_toto_t;
937 Moreover, only toto_t (and e_toto_t) are public. The rest (mainly
938 s_toto_t) is private.
940 - While I was at it, all gras_<obj>_free() functions want a gras_<obj>_t*
941 so that it can set the variable to NULL. It was so for dicts and sets,
942 it changed for dynars.
944 - Fix a bunch of memleaks in dict_remove
945 - Fix a bug in sg/server_socket opening: it failed all the time.
947 2004-10-07 Martin Quinson
948 - Speed up dynar lookup operation a bit.
950 gras_dynar_get is dead.
952 Now, you can choose between gras_dynar_get_cpy (the old gras_dynar_get
953 but should be avoided for efficiency reasons) and gras_dynar_get_ptr
954 (which gives you the address of the stored data).
956 gras_dynar_get_as is an helpful macro which allows you to retrieve a
957 copy of the data using an affectation to do the job and not a memcpy.
959 int toto = gras_dynar_get_as(dyn,0,int); rewrites itself to
960 int toto = *(int*)gras_dynar_get_ptr(dyn,0);
962 It does not really speedup the dynar test because they are
963 setting elements all the time (and look them seldom). But the dict does
964 far more lookup than setting.
966 So, this brings the dict_crash test from ~33s to ~25s (200000 elms).
968 2004-10-05 Martin Quinson
969 - Allow to (en/dis)able the cycle detection at run time.
971 Whether we should check for cycle or not is now a property of each
972 datatype. When you think there may be some cycle, use datadesc_cycle_set.
973 datadesc_cycle_unset allow to remove this property when previously set.
975 Note that the cycle detection is off by default since it impacts the
976 performance. Watch the data you feed GRAS with ;)
978 This property is hereditary. Any element embedded in a structure having it
979 set have it set for the time of this data exchange.
981 You should set it both on sender and receiver side. If you don't set it on
982 sender side, it will enter an endless loop. If you forget on receiver
983 side, the cycles won't be recreated after communication.
985 - Header reorganization.
986 Kill gras_private.h, each submodule must load the headers it needs.
988 2004-10-04 Martin Quinson
989 - Interface revolution: do not try to survive to malloc failure.
991 Now, gras_malloc and friends call gras_abort() on failure.
992 As a conclusion, malloc_error is not a valid error anymore, and all
993 functions for which it was the only gras_error_t return value are
994 changed. They now return void, or there result directly.
995 This simplify the API a lot.
997 2004-09-29 Martin Quinson
998 - Re-enable raw sockets.
999 Created by gras_socket_{client,server}_ext;
1000 Used with gras_raw_{send,recv}
1003 It should allow to kill the last bits of gras first version soon.
1005 This is not completely satisfactory yet (duplicate code with
1006 chunk_{send,recv}; a bit out of the plugin mechanism), but it should
1009 - Simplify transport plugin (internal) interface by not passing any
1010 argument to _server and _client, but embedding them in the socket
1013 2004-09-28 Martin Quinson
1014 - Finish the port to AIX.
1015 autoconf was my problem (segfault within the malloc replacement
1016 function. No idea why)
1018 2004-09-16 Martin Quinson
1019 - Fix some size_t madness on 64bit architectures.
1021 2004-09-08 Martin Quinson
1022 - Reduce the number of system headers loaded, overload some more system
1023 calls (such as malloc to cast the result of the system one, and work
1025 - Fix and reintroduce the config support
1027 2004-09-07 Martin Quinson
1028 - Source code reorganization to allow Arnaud to surf all over there.
1029 - Allow to document the logging categories.
1030 - Remove all uppercase from logging categories and useless cleanup in names.
1032 2004-08-18 Martin Quinson
1033 Version 0.6.2 (protocol not changed; API changed)
1034 - Interface cleanup: gras_msgtype_by_name returns the type (instead of a
1035 gras_error_t), and NULL when not found. Functions expecting a msgtype
1036 as argument (msg_wait; msg_send) deal with NULL argument by providing a
1037 hopefully usefull message.
1038 - Portability to prehistoric sparcs again
1040 2004-08-17 Martin Quinson
1041 Version 0.6.1 (protocol not changed; ABI not changed)
1042 - prealloc some buffers to speed things up
1044 2004-08-11 Martin Quinson
1045 Version 0.6 (protocol not changed; ABI expended)
1046 - The parsing macro can deal with the references, provided that you add
1047 the relevant annotations (using GRAS_ANNOTE(size,field_name))
1049 2004-08-09 Martin Quinson
1050 Version 0.5 (protocol not changed; ABI changed)
1051 - Allow to off turn the cycle detection code in data exchange at
1052 compilation time. It should be at run time, but I'm short of time (and
1053 the config stuff is still broken). That way, we keep dict out of the
1054 critical path, which is good because the performance is poor:
1055 - search not dichotomial yet
1056 - dynar give no way to access their content and memcpy everytime
1057 - In composed data description (struct, ref and so on), stop foolness of
1058 keeping the subtype's ID, but store the type itself. This keeps sets out
1059 of the critical path, which is good since they rely on dynar and
1060 dictionnaries. The only loose of that is that we cannot detect the
1061 redeclaration of a structure/union with another content (but I'm not sure
1062 the code detected well this error before anyway). We still can detect
1063 the redefinition discrepancy for the other types.
1064 - Use a whole bunch of optimisation flags (plus -fno-strict-aliasing since
1065 it breaks the code because of type-punning used all over the place).
1066 This breaks on all non-gcc architectures (for now).
1068 All those changes (plus the buffer of last time) allow me to gain 2 order
1069 of magnitude on cruel tests consisting of 800000 array of integers on two
1070 level of a hierarchical structure (200 secondes -> 4 secondes)
1073 - the selector of reference must now return the type it points to, not
1074 the ID of this type.
1076 2004-08-06 Martin Quinson
1077 Version 0.4 (protocol changed; ABI not changed)
1078 - Allow to pass --gras-log argument to processes in simulation mode. Really.
1079 - New debugging level: trace (under debug) to see effect of GRAS_IN/OUT
1080 - Implement a buffer transport, and use it by default (it relies on tcp in
1081 real life and on sg in simulation).
1082 That's a bit hackish since I had a new field to the structure to store
1083 its data without interfering with the subtype ones. Inheritance
1084 is tricky in C. And that's a kind of reverse inheritance with one class
1085 derivating two classes. Or maybe a game with java interfaces. Anyway,
1086 that's damn hard in C (at least).
1087 Moreover, I got tired while trying to ensure plugin separation and
1088 genericity in SG mode. MSG wants me to do weird things, so let's go for
1089 cruel hacks (temporarily of course ;).
1090 See comment in transport_private.h:71
1091 - do not include all the _interface headers in private but in the files
1092 which really need them (to cut the compilation time when they are
1095 2004-07-26 Martin Quinson
1096 Version 0.3 (protocol not changed; ABI changed)
1097 - Major overhault of the datadesc interface to simplify it:
1098 - shorted the function names:
1099 s/gras_datadesc_declare_struct/gras_datadesc_struct/ and so on
1100 - add a trivial way to push/pop integers into the cbps without malloc.
1101 This allows to make really generic sub_type description, which simply
1102 pop their size of the stack.
1103 - add a function gras_datadesc_ref_pop_arr() which does what users want
1104 most of the time: Declare a dynamic array (which pops its size of the
1105 stack) and declare a reference to it. Poor name, but anyway.
1106 - kill the post-send callback, add a post-receive one
1108 2004-07-23 Martin Quinson
1109 Version 0.2 (protocol changed; ABI changed)
1110 - add some testing for cpbs in the test cases, and fix some more bugs.
1111 This invalidate again the little64 data file, since I cannot regenerate
1113 - remove an awfull optimization in the logging stuff, allowing me to:
1114 - understand it again
1115 - learn gcc how to check that the argument match the provided format
1116 - fix all errors revealed by gcc after that
1117 - internal keys of dict are not \0 terminated. Deal with it properly in
1118 loggings instead of segfaulting when the user want to see the logs :-/
1120 2004-07-22 Martin Quinson
1121 - Fix some stupid bug preventing cbps (callback postit) from working
1123 2004-07-21 Martin Quinson
1124 - Some documentation cleanups
1125 - remove the useless last argument of msgtype_declare
1126 - rename the Virtu functions to fit into the 'os' namespace
1127 - move headers src/include -> src/include/gras/ and stop fooling with
1128 gras -> . symbolic link
1129 - make distcheck is now successful
1131 2004-07-19 Martin Quinson
1133 - Build shared library also
1134 - Install html doc to the right location
1135 - stop removing maintainer files in make clean
1136 - build tests only on make check
1138 2004-07-13 Martin Quinson
1140 - No major issue in previous version => change versionning schema
1141 - Re-enable little64 convertion test now that Abdou kindly regenerated the
1142 corresponding dataset.
1144 2004-07-11 Martin Quinson
1146 - Get it working with any kind of structure (we can compute the padding
1147 bytes remotely for all the architectures I have access to)
1148 - Implement the structure parsing macro (still not quite robust/complete)
1149 - Improvement to the remote testing toysuite
1151 2004-07-10 Martin Quinson
1152 [autoconf mechanism]
1153 - get ride of a bunch of deprecated macros
1154 - actually run the test for two-compliment, not only compile it :-/
1155 - test whether the structures get packed (and bail out if yes. Damn.
1156 Alignment is a serious matter)
1157 - test whether the structures get compacted (but respecting the alignment
1158 constraints of each types)
1159 - test whether the array fields of structures can straddle alignment boundaries
1161 - Damnit, double are bigger than float (typo in creation of 'double' datadesc)
1162 (took me 2 hours to find that bug, looking at the wrong place)
1163 - Add gras_datadesc_declare_{union,struct}_close(). They must be used
1164 before sending/receiving and are used to compute the offsets of fields
1165 - Given that padding size depend even on compiler options, keep track of
1166 alignment and aligned_size only for the current architecture. Not a big
1167 deal since we send structure fields one after the other (seems
1169 - Add the datastructure used for IEEE paper by the PBIO guys to the test
1170 program, let it work on linux/gcc/little32. portability todo.
1172 2004-07-08 Martin Quinson
1173 - import and improve remote compilation support from FAST
1174 - make sure make check works on half a dozen of machines out there
1176 2004-07-07 Martin Quinson
1177 Let's say it's version 0.0.3 ;)
1178 - Implement conversions (yuhu!)
1179 - Let it work on solaris (beside conversion, of course)
1180 - Stupid me, using rand() to generate the conversion datatests in not wise.
1182 2004-07-06 Martin Quinson
1183 - Let make dist work, since I'm gonna need it to compile on remote hosts
1184 - Let Tests/datadesc_usage write the architecture on which the file was
1185 generated as first byte.
1186 - Add PowerPC (being also IRIX64), SPARC (also power4) and ALPHA
1187 architecture descriptions.
1188 - Add datadesc_usage.{i386,ppc,sparc} files being the result of execution
1189 on those architectures.
1190 - Optimization: send/recv array of scalar in one shoot
1192 2004-07-05 Martin Quinson
1193 - YEAH! GRAS/SG and GRAS/RL are both able to run the ping example !
1195 - Plug a whole bunch of memleaks
1196 - each process now have to call gras_{init,exit}. One day, their log
1197 settings will be separated
1198 - Continue the code factorisation between SG, RL and common in Transport.
1200 2004-07-04 Martin Quinson
1202 - Redistribution between SG and RL.
1203 We wanna have to accept in SG, so move accepted related parts of RL in
1204 the common part. (more precisely, the dynar of all known sockets is no
1205 more a static in transport.c, but part of the process_data)
1207 [gras_stub_generator]
1208 - Bug fix: Do call gras_process_init from gras_init (wasnt called in RL).
1210 2004-07-03 Martin Quinson
1211 - Create a new log channel tbx containing dict, set, log, dynar (to shut
1212 them all up in one shot)
1214 - Fix the ugly case of reference to dynamic array.
1215 - New (semi-public) function gras_datadesc_size to allow the messaging
1216 layer to malloc the needed space for the buffer.
1218 - gras_socket_close now expect the socket to close (and not its address to
1219 put NULL in it after it). This is because the socket passed to handlers
1220 is one of their argument (=> not writable).
1222 - propagate the interface cleanup from last week in datadesc, ie remove a
1223 superfluous level of indirection. User pass adress of variable
1224 containing data (both when sending and receiving), and not of a variable
1225 being a pointer to the data. Let's say that I like it better ;)
1226 The price for that is constructs like "int msg=*(int*)payload" in
1227 handlers, but it's a fine price, IMHO.
1229 - Let it work in RL (yuhu)
1231 2004-06-21 Martin Quinson
1233 - porting SG plugin and SG select to new standards (works almost).
1234 - plug memleaks and fix bugs around.
1237 - cleanup the prototype of data recv and force users to specify when they
1238 want to handle references to objects. Test case working even for cycles.
1239 - plug memleaks. Valgrind is perfectly ok with this.
1241 2004-06-12 Martin Quinson
1243 - cleanup the separation between plugin and main code in plugin creation
1245 2004-06-11 Martin Quinson
1247 - Reput hook for raw sockets, needed for BW experiments
1248 - kill a few lines of dead code
1249 [Data description] Interface cleanup
1250 - gras_datadesc_by_name returns the searched type or NULL.
1251 That way, no variable is needed to use a type desc once, which makes
1253 - gras_datadesc_declare_[struct|union]_append_name is removed. The last
1254 two parameters were strings (field name, type name), leading to
1256 [Dicos] Interface cleanup
1257 - gras_dico_retrieve -> gras_dico_get ; gras_dico_insert -> gras_dico_set
1258 This is consistant with the dynar API.
1260 2004-04-21 Martin Quinson
1262 - Porting to new standards.
1264 - interface cleanup.
1265 There is no bag anymore, no need to take extra provision to mask the
1266 pointers behind "ID".
1267 Better splitup of functions between files create/exchange/convert.
1268 This is still a bit artificial since convert and receive are so
1269 interleaved, but anyway.
1271 - add a queued message list to procdata (the ones not matching criteria
1273 - factorize some more code between SG and RL wrt procdata
1275 - use gras_exit in example to track memleaks
1276 - get rid of gs_example now that GS is properly integrated into gras
1277 - update run_test to integrate the lastest tests (datadesc)
1279 - rename WARNINGn macros to WARNn since it prooved error-prone
1281 2004-04-19 Martin Quinson
1283 - register init/exit functions within gras module mechanism
1284 - send/receive function.
1285 Convertion is not implemented, but short-cutted if not needed.
1286 struct/array elements are sent one by one (instead of block-wise), but
1287 nobody really cares (yet). Get a prototype before optimizing.
1288 - tests (using a file socket) for DD send/receive on:
1289 - base types: int, float
1290 - array: fixed size, string (ie ref to dynamic string)
1291 - structure: homogeneous, heterogeneous
1292 - chained list, graph with cycle
1293 Believe it or not, valgrind is not too unhappy with the results. The
1294 cycle happily segfaults, but the others are ok. And I'm sick of pointers
1298 - Bugfix when using a filename explicitely (instead of '-')
1300 2004-04-09 Martin Quinson
1302 - factorize more code between RL and SG in socket creation
1303 - Complete the implementation and tests of:
1305 o file (only in RL, and mainly for debugging)
1307 I lost 3 days to design a portable address resolver, and then decided
1308 that the prototype mainly have to run on my box.
1309 Addressing portability too early may be like optimizing too early :-/
1311 - use gras_init in the Tests instead of the crappy parse_log_opt
1312 (the latter function is removed)
1313 [Conditional execution]
1314 - New functions: gras_if_RL/gras_if_SG (basic support for this)
1315 [Code reorganisation]
1316 - Get rid of libgrasutils.a since it makes more trouble than it solves.
1317 Build examples against the RL library, since there is no way to disable
1318 its creation for now.
1320 For information, the beginning of coding on GRAS was back in june
1321 2003. I guess that every line has been rewritten at least twice since
