+SimGrid (3.4-svn) unstable; urgency=low
+
+ The "Easter in Cargese" release. Also known as (major changes):
+
+ * the "se habla Java, Ruby 話せます, fala-se Lua (and deaf-friendly)"
+ ~> bindings were greatly improved
+ ~> new tracing infrastructure for better visualization introduced
+
+ * the "Welcome to configury modernity" release.
+ ~> we switched from autotools to cmake, and improved our cdash
- The "C spoken, se habla Java, Ruby 話せます, fala-se Lua" release.
+
+ A more detailled list of changes follow (full detail in svn log).
Java Bindings: Various Cleanups
+ * (install java-gcj-compat-dev on debian-like to use them)
* Remove put/get: no need to export deprecated interface in Java
Use send/receive instead.
* Cleanup the examples and add a README per directory
* Cleanup the exceptions that may get thrown by each function
* Other internal cleanups in Java bindings. Performance still bad :/
Ruby and Lua Bindings: create them
+ * (install ruby1.8-dev/liblua5.1-0-dev on debian-like to use them)
* That's new and great, you should try them out.
Same functionalities than Java bindings, only even less polished
SimDag:
* SD_SCHED_NO_COST: Constant to use as cost in SD_task_schedule()
either as comm costs or compute costs to mean that there is no
such thing for that specific task.
+ * Add a SD_task_set_name() function
* Fix SD_task_unschedule() on typed tasks
* Fix SD_task_get_execution_time() to return seconds, not flop*sec
+ * In DAX loader, accept useless 'level' attributes to <job> since
+ LIGO DAGs have them (seem to be to ease graphical representation).
MSG:
- * In trace replay, allow to have one trace file per process.
- Give the specific trace file as argument of each process,
- and call MSG_action_trace_run(NULL)
- You can still have one merged file for each processes.
+ * Add an example masterslave_mailbox.c using send/receive and not
+ the deprecated put/get interface.
* Kill the MSG_paje_output() function. It's a noop since 2 years.
* Kill MSG_WARNING and MSG_FATAL return codes: they were not used
anywere in source.
* Rename MSG_TIMEOUT_FAILURE into MSG_TIMEOUT for sake of logic
+ (declare MSG_USE_DEPRECATED to still have the old name)
* Add a MSG_task_set_data() function
* About trace replay (see examples/msg/actions):
- implement barrier
- Allow to work with splitted trace files for each process
+ Give the specific trace file as argument of each process,
+ and call MSG_action_trace_run(NULL)
+ You can still have one merged file for all processes.
- Fix implementation of collective operations
SMPI:
* This is the first release of SimGrid where SMPI is not considered
- smpicc passes -O2 by default (just like openmpi one)
SIMIX:
* add SIMIX_action_suspend() and SIMIX_action_resume() functions
+ * Bug fixes about timeouts during communications
* add SIMIX_message_sizes_output() as a pimple to write to file the
amount of messages per size. Use gnuplot to get histogram.
Pimple because that's the only user-visible function of simix,
maestro.
- Merge context_start into context_new for sake of simplicity
SURF:
+ * Add a Vivaldi network model, coded live during SUD'10 ;)
* Rename configuration variables to start a hierarchy:
o cpu_model -> cpu/model
o network_model -> network/model
traces with the Triva tool is written.
* More information about: SimGrid FAQ (in the section Tracing Simulations
for Visualization)
-
+ Build system:
+ * We moved to cmake as default build system. Autotools support will
+ be dropped soon. Check the FAQ for more info about how to use it.
+ * Greatly improved our cdash/ctest interactions
+ Check http://cdash.inria.fr/CDash/index.php?project=Simgrid
+ * Added memory checking tests with valgrind; lot of memleak fixing.
+ This may be the first release of simgrid with so few memory issues
+ * Added code coverage tests.
+ Our coverage is still improvable, but at least we see it on cdash.
