Dear all,
I do my PhD in physics and use a program, which uses openmpi for
a sophisticated calculation.
But there is a Problem with "max. message size ". That is limited to ~2GB.
Someone suggested that I have to use chunks i.e. I have to
disassemble the massages
in smaller massages. That
if (source == MPI_ANY_SOURCE) source = status->MPI_SOURCE;
if (tag == MPI_ANY_TAG) tag = status->MPI_TAG;
}
buf += c;
}
}

B/RDMA is limited to
2G, but OMPI 1.7 splits large buffers during RDMA into 2G chunks.
