-SimGrid (2.94-cvs) UNRELEASED
-
-----
-TODO
-----
-
-- Stop layering gras over msg?
-- Pre-compilation of data_send/recv?
-- Exception revolution?
-All of them seem to be post-SG3 issues.
-
-Rather finalize what's underway and finish the Big Cleanup:
- - Check what can be cut from the xbt
- - "pull" code diffusion in graspe
- - document the gras' timing macro
- - add a real implementation (even if simplistic) to gras_os_myname
-

-DONE

+
+SimGrid (2.96) unstable; urgency=low
+
+ AKA SimGrid 3 rc 2.
+
+ XBT:
+ * New! Exception handling with setjmp or such (code from OSSP ex) [MQ]
+ This deprecates the xbt_error_t mecanisms.
+ It modifies (simplifies) all XBT and GRAS API.
+ MSG API keeps unchanged (exceptions raised by XBT are catched from
+ within MSG and masked with existing error handling facilities)
+
+ SURF:
+ * New! Add a FATPIPE model. [AL]
+ * New! Add a parallel task model. [AL]
+ * New! Add automatically a loopback interface (in the default
+ network model) if none was precised.
+
+ MSG
+ * Bugfix: MSG_process_resume now works with the current running process.
+ [AL]
+ * New! Add MSG_parallel_task_create and MSG_parallel_task_execute. [AL]
+ * Modification of MSG_task_get_compute_duration. Once a task has been
+ processed, the value returned by this function is now equal to 0. [AL]
+ * New! Add double MSG_task_get_remaining_computation(m_task_t task) and
+ MSG_error_t MSG_task_cancel(m_task_t task). Add a state
+ (MSG_TASK_CANCELLED) to MSG_error_t corresponding to the cancelation
+ of a m_task. For now, MSG_task_cancel only works with computation
+ tasks. [AL]
+ * New! Add double MSG_get_host_speed(m_host_t h) that returns the speed
+ of the processor (in Mflop/s) regardless of the current load on the
+ machine. [AL]
+ * API Change: use proper naming convention for MSG_getClock and
+ MSG_process_isSuspended: MSG_get_clock and MSG_process_is_suspended.
+ [AL]
+ * New! Add void MSG_task_set_priority(m_task_t task, double priority).
+ This function changes the priority of a computation task. This priority
+ doesn't affect the transfer rate. A priority of 2 will make a task
+ receive two times more cpu power than the other ones. This function
+ has been added to suit the needs of Nguyen The Loc and hasn't been that
+ much tested yet. So if it fails, please report it and send me your code.
+ [AL]
+ * API Change: removed all functions and types that were marked "deprecated"
+ since many months. Renamed MSG_global_init_args to MSG_global_init.

+
+ XBT
+ * Steal some nice code to GNU pth to fix context detection and usage [AL]
+ * Cleanup in the xbt_config API; add configuration callbacks. [MQ]
+ * Cleanup in the initialization API: the unused "defaultlog" is dead. [MQ]
+
+ SURF
+ * Bugfix: Allow absolute paths for platform description files [MQ]
+ * Bugfix: do free the variables after use. Leads to drastic performance
+ improvement [AL]
+ * Implement max_duration (ie, timeouts) on resources [AL]
+
+ MSG
+ * Implement MSG_config to configure MSG at runtime. xbt_cfg test on a real
+ case ;) [MQ]
+ * Implement MSG_channel_select_from() to help GRAS now that SURF provide
+ the needed support (timeouts) [AL]
+
+ GRAS (new features)
+ * Implement measurement sockets. You can now get the bandwidth between two
+ hosts thanks to AMOK (see below). [MQ]
+ * gras_datadesc_dynar() builds a dynar type descriptor, allowing to send
+ dynar over the network (yeah) [MQ]
+ * Real (even if simplistic) implementation of gras_os_myname() on RL [MQ]
+ * simple/static token-ring example. [Alexandre Colucci and MQ]
+ * Use MSG_channel_select_from() and remove the *slow* hack we had to put
+ in place before [MQ]
+
+ GRAS (bug fixes)
+ * Differentiate the types "char[22]" and "unsigned char[22]" in automatic
+ type parsing. "short" and "long" modifiers were also ignored; other
+ modifier (such as reference level) are still ignored. [MQ]
+ * Embeed the buffer size within the buffer itself on SG. [MQ]
+ That way, send() are atomic and cannot get intermixed anymore (at least
+ the ones which are less than 100k; bigger messages still have the issue)
+ * Array size pushed by the field, not by the field type (or each
+ and every long int will push stuff to the cbps) [MQ]
+ * use select() to sleep since it allows to portably sleep less than one
+ second. [MQ]
+
+ GRAS (minor cleanups)
+ * <project>.Makefile.local (generated from gras_stub_generator) |MQ]:
+ - Do clean .o files
+ - Compile with -g
+ * Type Callbacks now receive the gras_datadesc_type_t they work on as argument.
+ * type category 'ignored' killed as it was never used and were difficult
+ to transmit.
+ * whether a type can cycle or not is now a flag, leaving room for more
+ flags (as "ignored", if we feel the need one day ;)
+ * Rename raw sockets to measurement sockets since "raw" has another
+ meaning in networking community.
+
+ AMOK
+ * Advanced Metacomputing Overlay Kit introduction. It is based over GRAS
+ and offers features not belonging to GRAS but that most applications
+ need. One day, it may be a set of plugins loadable at runtime.
+ * New module: bandwidth
+ bandwidth measurement between arbitrary nodes running this module. [MQ]

+
+ The first beta release of SimGrid 3 !
+
+ >>>Arnaud<<<
(documentation)
* Update the main page and the FAQ. Adding references to gforge.
-
+
(gras)
* Add a gras_os_getpid function.
(msg)
* Add MSG_task_get_compute_duration() and MSG_task_get_data_size()
* Extend the logs so that they also print PID, hostname, date, ... if
- available.
+ available.
* Convert the MSG example to the use of xbt_logs instead of PRINT_MESSAGE,
and kill the old version which were in testsuite/
* Rewrite tools/MSG_visualization/colorize.pl for using with logs instead
(xbt)
* Add xbt_os_time(). As the rest of xbt/portability, this is not public
for users. Instead, each programming environment (GRAS, MSG,...) use it
- when needed to provide such a feature to users.
+ when needed to provide such a feature to users.
Don't shortcut the mecanism or you will also shortcut the virtualization
you need on the simulator.
- [Martin]
+ >>>Martin<<<
(infrastructure)
* Cleanups in configury with regard to compile optimization/warning flags.
Also add -fno-loop-optimize to any powerpc since it's the optimization
* Doxygen cleanups: move MSG examples, kill the second Doxygen phase
needed by MSG examples complications
* Borrow configury beautifications from PHP
-
+
(xbt)
* Bugfix: XBT_LOG_NEW_DEFAULT_CATEGORY now compiles without compiler
warning (thanks loris for stumbling into this one).
-
+ * Bugfix: stop loading private headers (gras_config.h) from the public
+ ones (xbt/swag.h).
+
(gras)
* Change SIMGRID_INSTALL_PATH to GRAS_ROOT in Makefiles generated for user.
* Rename gras_get_my_fqdn to gras_os_myname and implement it in the simulator
RL would imply a DNS resolver, which is *hard* to do in a portable way
(and therefore delayed).
-
- --
+ * Implement a real timer mecanism and use it in timing macros. This allows
+ to avoid rounding errors and get a 0.000005 sec precision in timing
+ macros. While I was at it, various cleanups:
+ - allow to declare more than one timed section per file (fix a stupid bug)
+ - move some private declaration to the right place
+ - merge conditional execution and timing macros into emulation module
+ - document the module
+ - make sure the module cleanups its mess on gras_exit
+ * Documentation improvements:
+ - (new) how to compile applications using GRAS
+ - (new) emulation support (timing macros)
