[mvapich-discuss] MVAPICH2-x 2a error on MPI_Get_accumulate

[Sayan Ghosh]

I get this error using MVAPICH2-X 2a:

[vs64:mpi_rank_0][MPIDI_CH3I_RDMA_try_rma]
src/mpid/ch3/channels/mrail/src/gen2/rdma_iba_1sc.c:1084: rdma_iba_1sc
[vs66:mpi_rank_1][MPIDI_CH3I_RDMA_try_rma]
src/mpid/ch3/channels/mrail/src/gen2/rdma_iba_1sc.c:1084: rdma_iba_1sc

Does it means mvapich2-x is not able to understand the particular type of
one-sided op? The code underneath is just MPI_Get_Accumulate to emulate
ordered RMA:

        MPI_Get_accumulate(NULL, 0, MPI_DATATYPE_NULL,                /*
origin */
                           target, count, mpi_type,                   /*
result */
                           pe, (MPI_Aint)win_offset, count, mpi_type, /*
remote */
                           MPI_NO_OP,                                 /*
atomic, ordered Get */
                           win);
