Macros ensure the backwards compatibility, but you should fix your code
SMPI
+ - Major C++ rewrite ongoing (SMPI used to be C compiled in C++). This can break codes that were using internals of SMPI (from private.h instead of the public smpi.h).
- Bump our claim of support from MPI 1.1 to MPI 2.2. We don't support 100% of
it, but it should be enough. Contact us if not.
- New algorithm for SMPI_SHARED_MALLOC: global, where all blocks are
- RMA : MPI_Accumulate are applied in correct order, and
MPI_Win_complete or MPI_Win_post shouldn't miss messages anymore.
- Better support for MPI_IN_PLACE
+ - Support for MPI_Win attrs and keyvals.
- Support MPI_Comm_group_create, MPI_Type_size_x
+ - MPI ops should be properly applied to all allowed types
- Replace implementation of MPI_Bcast "scatter followed by rdb allgather"
algorithm by a non failing one from mpich.
