Dear all, I have notice small difference between OPEN-MPI and intel MPI. For example in MPI_ALLREDUCE in intel MPI is not allowed to use the same variable in send and receiving Buff.
I have written my code in OPEN-MPI, but unfortunately I have to run in on a intel-MPI cluster. Now I have the following error: *atal error in MPI_Isend: Invalid communicator, error stack:* *MPI_Isend(158): MPI_Isend(buf=0x1dd27b0, count=1, INVALID DATATYPE, dest=0, tag=0, comm=0x0, request=0x7fff9d7dd9f0) failed* This is ho I create my type: * CALL MPI_TYPE_VECTOR(1, Ncoeff_MLS, Ncoeff_MLS, MPI_DOUBLE_PRECISION, coltype, MPIdata%iErr) * * CALL MPI_TYPE_COMMIT(coltype, MPIdata%iErr)* * !* * CALL MPI_TYPE_VECTOR(1, nVar, nVar, coltype, MPI_WENO_TYPE, MPIdata%iErr) * * CALL MPI_TYPE_COMMIT(MPI_WENO_TYPE, MPIdata%iErr)* do you believe that is here the problem? Is also this the way how intel MPI create a datatype? maybe I could also ask to intel MPI users What do you think? Diego
