+ SimDag
+ * Warn the user about loop dependencies in data flow of DAX files
+ * Obey the control-flow dependencies of DAX files
+
+ Cmake
+ * Add option "enable_smpi" allowing to not compile SMPI.
+ Probably useful for the (Mac) users experiencing a build error here
+ * Improve the detection of lua5.1 and ruby1.8

+SimGrid (3.4) stable; 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
+
+
+ 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
+ * Remove example autoDestination (that's the only way to go now)
+ * Remove example explicitDestination (was a plain copy of basic)
+ * Make JniException a runtime exception, so that there is no need to
+ declare the fact that you may encounter such a beast. I guess that
+ nobody will ever want to survive such error.
+ * Create specific errors for each MSG case of failure:
+ host failure, transfer failure, timeout, task cancelled
+ * 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:
+ * Kill the useless "rate" argument of SD_task_get_execution_time()
+ Everyone used to provide -1 as a value, it was not used, and the
+ semantic of a possible use wasn't even clear.
+ * 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:
+ * 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
+ * Allow task_execute() on 0-sized tasks (closes #10063)
+ SMPI:
+ * This is the first release of SimGrid where SMPI is not considered
+ beta anymore (even if some corners should still be improved)
+ * Port over the new SIMIX_network submodule (internal refactoring)
+ * Basic support to log events as with SMPE (use --cfg=SMPE:1)
+ * Implement more missing elements of the standard:
+ - MPI_COMM_SELF
+ - MPI_MAXLOC MPI_MINLOC + all associated datatype MPI_DOUBLE_INT,
+ MPI_FLOAT_INT, etc.
+ - MPI_Address() MPI_Get_count() MPI_Type_free() MPI_Type_extent()
+ MPI_Scan() MPI_Get_processor_name()
+ - Added implementation of missing case for Alltoall (warning: it's
+ *not* the bruck variant from OpenMPI; based on Alltoallv instead)
+ - SMPI_MPI_Gather() SMPI_MPI_Gatherv() SMPI_MPI_Scatterv()
+ SMPI_MPI_Reduce_scatter() SMPI_MPI_Allgather()
+ SMPI_MPI_Allgatherv()
+ * Bug fixes include:
+ - MPI_Waitsome() was broken
+ - Allow relative includes in smpicc
+ - Command line cfg argument 'reference_speed' was ignored...
+ - Some functions did not properly lead to auto-benching of user code
+ - smpicc passes -O2 by default (just like openmpi one)
