SMPI:
- Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
too often and provide more accurate timings.
+ - Add -gdb and -lldb shortcuts to help debug MPI codes with smpirun
+ - 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_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.
