Ralph, I think David's concern is that because Slurm has changed their default behavior, Open MPI's default behavior has changed as well. The request (on which I have no opinion) appears to be that ORTE make an explicit request for the behavior that was the previous default in Slurm. That would ensure that the behavior of Open MPI remains independent of the Slurm version.
David, The problem here appears to be that the new (--export=NONE) behavior means that $PATH and/or $LD_LIBRARY_PATH are not propagated, and thus orted could not be found. I believe you can configure Open MPI with --enable-mpirun-prefix-by-default to resolve the reported "orted: No such file or directory" -Paul On Fri, Apr 17, 2015 at 1:13 PM, Ralph Castain <r...@open-mpi.org> wrote: > Hmmm...but what if a user -doesn't- want their environment forwarded?
