The issue is that openpty() is failing on the machine. I think /dev/ptmx
and /dev/pts have to exist for pty support to work properly. We're having
the same issue on Coyote, but not on Pink and Flash. As far as I can
tell, those are the files / directories that are on the working systems
but not
I'm testing out a new OpenMPI 1.1.2 build on a machine here at LANL
and get the following at launch:
% mpirun -np 4 IMB-MPI1
[n254:07650] pls_bproc_orted: openpty failed, using pipes instead
[n255:07651] pls_bproc_orted: openpty failed, using pipes instead
[n254:07650] pls_bproc_orted: openpty
