Hi Jim, can you please provide minimal instructions on how to reproduce the issue ? we know Open MPI, but i am afraid few or none of us know about Rmpi nor doMPI. once you explain how to download and build these, and how to run the failing test, we ll be able to investigate that.
also, can you describe your environment ? i assume one ubuntu machine, can you please run lstopo on and post the output ? did you use to have some specific settings in the system-wide conf file (e.g. /.../etc/openmpi-mca-params.conf) ? if yes, can you post these, the syntax might have changed in 3.0.0 Cheers, Gilles On Tue, Oct 3, 2017 at 7:34 PM, Jim Maas <jimmaa...@gmail.com> wrote: > I've used this for years, just updated open-mpi to 3.0.0 and reloaded R, > have reinstalled doMPI and thus Rmpi but when I try to use startMPICluster, > asking for 6 slots (there are 12 on this machine) I get this error.
