SimGrid (3.4-svn) unstable; urgency=high
OVERALL CHANGES:
- * Also include strbuff from xbt.h public header
-
+ * Tested successfully on AIX
+ * Implement a --cfg-help to show existing configuration variables
+
GRAS:
* fix a bug on struct sizeof computation, which prevented the
exchange of arrays of structs in some conditions
-
+ - added a regression test about this in datadesc_usage
+ * Allow the exchange of 0-long dynamic vectors.
+ - for that, use -1 as indicator of dynamic size instead of 0
+ - This implied to change any size from unsigned long to long,
+ reducing a bit communication abilities, but I guess that with
+ 64bits being quite common, this is more than enough.
+ - This also induce a protocol change, thus bumping network protocol
+ version from 0 to 1 (if we have external users, we have to get
+ clean on that point too ;)
+ - added two regression tests about this in datadesc_usage
+ * Be more verbose when propagating local exceptions
+ This helps debugging.
+ * Display the status of simulated processes when receiving SIGINT in
+ simulation mode
+
MSG:
* Allow to control the simulation from a trace file.
New functions MSG_action_register() and MSG_action_trace_run()
kind of action while the second one parses a trace file and
triggers the corresponding actions within the system.
For now, only a toy example is provided in examples/msg/actions
-
+ * Add an exemple of process migration in examples/msg/migration
+ * Fix a bug in task exchange which broke MSG_task_get_sender()
+ Add a teshsuite regression test for that.
+ [Bug: if MSG_task_get_sender() is called after sender exit,
+ bad things happen]
+ * Fix a bug which prevented suspend/resume to work properly
+ * Display the status of simulated processes when receiving SIGINT
+ This fixes a regression of v3.3. due to the introduction of SIMIX
+ * Bug fixing in failure management:
+ - trace could not start by a failure at time 0
+ - failure during communications were not working
+
SIMIX:
* Add SIMIX_process_set_name() to change the name of the current
process in the log messages.
+ * Store smx_hosts in a dict since we only retrieve them by name
+ * Move the configuration infrastructure to surf
+
+ SIMDAG:
+ * Move the configuration infrastructure to surf
+
+ SMPI:
+ * Massive internal cleanups:
+ - Store internal structures on processes instead of hosts (allows
+ to have more than one process per host, in addition of being more
+ logical)
+ - Cleanup the initialization/finalization process
+ - Kill a whole bunch of unneeded synchronization:
+ processes run in exclusive manner within the simulator
+ - Move queues from global tables to process data fields
+ * Improve smpirun:
+ - now accept -platform and -hostfile arguments
+ - Pass the right rank value to processes according to the hostfile
+ * Compile the examples by default, and use them as regression tests
+ * Implement MPI_Wtime()
+
+ SURF:
+ * TCP_gamma can now be specified as command line option using
+ --cfg=TCP_gamma:10000000.0
+ * Change the --surf-path cmd line option into --cfg=path:
+
+ XBT:
+ * Also include strbuff from xbt.h public header
+ * xbt_ex_display(): do not free the exception after displaying
+ This allows to do more with the given exception afterward.
+ Users should call xbt_ex_free() themselves.
+
+ Build Chain:
+ * Do not require doxygen in maintainer mode

For information, the beginning of coding on GRAS was back in june
2003. I guess that every line has been rewritten at least twice since
-then.
