I'm wondering if Intel MPI has the facility to allow me to pin processes, not only to specific nodes within my cluster, but to specific cores within those nodes. With Open MPI, I can set up a rankfile that will give me this fine-grained capability, that is, I can assign each MPI process rank to a specific node and a given core on that node (logical or physical).
Granted, the rankfile idea from Open MPI is merely theoretical since the OS I have on the machines doesn't seem to abide by the assignments I make, but at least the possibility is there. I haven't found that level of control within the Intel MPI documentation. Any pointers or is this all just a pipe dream on my part?
