Sorry; I'm still not clear on exactly what you are trying to do, or how it is failing for you. Your copy-n-pasted output in the first mail appeared to be incorrect -- there was no command on the mpirun command line, and the strace output appears to be truncated.
Are you only running on a single node? Are you able to run hostname(1), or the MPI "hello world" or "ring" applications? Can you upgrade to a newer version of Open MPI? 2.0.x is very old -- 3.1.0 is the most recent. > On Aug 15, 2018, at 12:34 PM, Mota, Thyago <mo...@moravian.edu> wrote: > > Attached is the config.log and the ompi_info > > Thanks. > > On Wed, Aug 15, 2018 at 11:46 AM, Jeff Squyres (jsquyres) via users > <users@lists.open-mpi.org> wrote: > There can be lots of reasons that this happens.
