ahha, with --display-allocation I'm getting : mca: base: component_find: unable to open /sb/apps/openmpi/1.6.3/x86_64/lib/openmpi/mca_mtl_psm: libpsm_infinipath.so.1: cannot open shared object file: No such file or directory (ignored)
I think the system I compiled it on has different ib libs than the nodes. I'll need to recompile and then see if it runs, but is there anyway to get it to ignore IB and just use gigE? Not all of our nodes have IB and I just want to use any node. On Thu, Jan 24, 2013 at 8:52 AM, Ralph Castain <r...@open-mpi.org> wrote: > How did you configure OMPI?
