I've successfully installed the just released 1.1.2. So I go for a new round catching bugs, non standard behavior, or just what could be seen as convenient features.
The problem I've reported with MPI_GROUP_TRANSLATE_RANKS was corrected. However, looking at MPI-2 errata documment, it says: Add to page 36, after 3.2.11 (above) 3.2.12 MPI_GROUP_TRANSLATE_RANKS and MPI_PROC_NULL MPI_PROC_NULL is a valid rank for input to MPI_GROUP_TRANSLATE_RANKS, which returns MPI_PROC_NULL as the translated rank. But it seems it returns MPI_UNDEFINED in this case. Try yourself: In [1]: from mpi4py import MPI In [2]: group = MPI.COMM_WORLD.Get_group() In [3]: MPI.Group.Translate_ranks(group, [MPI.PROC_NULL], group) Out[3]: [-32766] In [4]: MPI.UNDEFINED Out[4]: -32766 Additionaly, OMPI segfaults if the group is MPI_GROUP_EMPY. Try yourself In [5]: group = MPI.GROUP_EMPTY In [6]: MPI.Group.Translate_ranks(group, [MPI.PROC_NULL], group) Signal:11 info.si_errno:0(Success) si_code:1(SEGV_MAPERR) Failing at addr:0xfffffff8 [0] func:/usr/local/openmpi/1.1.2/lib/libopal.so.0 [0xba1dfc] [1] func:[0xe67440] [2] func:/usr/local/openmpi/1.1.2/lib/libmpi.so.0(MPI_Group_translate_ranks+0xaa ) [0x5f0786] [3] func:/u/dalcinl/lib/python/mpi4py/_mpi.so [0xa5a6c6] [4] func:/usr/local/lib/libpython2.4.so.1.0(PyCFunction_Call+0x66) [0x1d5d66] # more traceback .....
