SMPI:
- Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
too often and provide more accurate timings.
+ - Add -gdb, -lldb, and -vgdb shortcuts to help debug MPI codes with smpirun
+ - MPI_Alltoallw support
+ - Partial MPI nonblocking collectives implementation: MPI_Ibcast, MPI_Ibarrier,
+ MPI_Iallgather, MPI_Iallgatherv, MPI_Ialltoall, MPI_Ialltoallv, MPI_Igather,
+ MPI_Igatherv, MPI_Iscatter, MPI_Iscatterv, MPI_Ialltoallw.
+ - MPI_Request_get_status, MPI_Status_set_cancelled, MPI_Status_set_elements
+ support
+ - Basic implementation of generalized requests (SMPI doesn't
+ allow MPI_THREAD_MULTIPLE) : MPI_Grequest_complete, MPI_Grequest_start
XBT:
- Drop sg_cmdline. Please use xbt_cmdline instead.
-fsplit-stack is the way to go nowadays when using threads.
- Drop the xbt_os_thread_t module (now unused)
- Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead.
+ - Drop xbt_str_join_array().
- Drop cunit, use Catch2 instead.
