S4U:
- Actor: Merge signals on_migration_start/end into on_host_change
- Actor: Rename migrate() into set_host()
+- Disk: Allow users to get the read and write nominal bandwidth values
+- Exec: Implement wait_for(timeout)
+- Io: Implement wait_for(timeout)
XML:
- Parse errors now raise a simgrid::ParseError that you may want to catch.
XBT:
- Remove unused parameter 'free_ctn' for xbt_dict_set() and xbt_dict_set_ext().
+- Drop unused xbt_dict and xbt_dynar functions.
+- New module: random, providing classical random numbers generators.
+
+SMPI:
+- New option : "smpi/auto-shared-malloc-thresh" which sets a value for
+ allocations' size above which they are considered "shared" by default (as if
+ they were performed through SMPI_SHARED_MALLOC macros).
+ Default = 0 = disabled feature.
+ Note : malloc, calloc and free are now overriden by smpicc/cxx by default.
+ This can cause some troubles if codes are already overriding these. If this
+ is the case, defining SMPI_NO_OVERRIDE_MALLOC in the compilation flags can
+ help, but will make this feature unusable.
+- Input check is now performed much more consistently and outputs precise
+ warnings for each error found
+- New supported calls : MPI_File_set_view, MPI_File_get_view
+- MPI I/O now only supports disks, as storage is discontinued.
+- MPI I/O allows opening files without specifying absolute path
+- Note : SMPI configuration options are now initialized by smpi_init_options()
+ call, which should be called if SMPI is not being used through smpirun.
Fixed bugs (FG#.. -> framagit bugs; FG!.. -> framagit merge requests):
- GH#31: [MC] please provide an option to make MPI_Send asynchronous
- GH#305: Unscheduled tasks are still excuted
+ - GH#313: smpirun: manual outdated w.r.t. --help
+ - GH#321: [S4U] Get task remaining work ratio
- GH#323: Crash when an actor turn off his physical host
- FG!19: Removing RngStream
+ - https://lists.gforge.inria.fr/pipermail/simgrid-user/2019-November/004653.html:
+ MPI_Cart_sub was not working properly. Kudos to Jonathan Borne for the report.
