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.
+ such thing for that specific task.
* Fix SD_task_unschedule() on typed tasks
+ * Fix SD_task_get_execution_time() to return seconds, not flop*sec
MSG:
* In trace replay, allow to have one trace file per process.
Give the specific trace file as argument of each process,
* About trace replay (see examples/msg/actions):
- implement barrier
- Allow to work with splitted trace files for each process
+ - Fix implementation of collective operations
+ 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)
SIMIX:
* add SIMIX_action_suspend() and SIMIX_action_resume() functions
+ * 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,
+ defined directly in xbt.h (irk, sorry)
* About semaphores:
- Add a SIMIX_sem_get_capacity() function
- Fix interactions with processe resume/suspende
- - release_forever was stupidly broken
+ - release_forever() was stupidly broken
+ - Fix SIMIX_display_process_status() for processes in a semaphore
- Make SIMIX_sem_block_onto() user-visible
* Refactoring context stuff:
- Use pseudo-OOP for better modularity
* Add a long description to the models, that users can see with such
argument on the command line: --cfg=cpu/model:help
* --help-models display the long description of all known models
- SMPI:
- * Implement MPI_Get_count, MPI_MAXLOC, MPI_MINLOC
XBT:
* config: add the ability to set a default value after registration
Does not override any previously set value (e.g. from cmd line)
