Red Hat Bugzilla – Bug 789150
SGE integration broken in openmpi-1.5.3
Last modified: 2014-08-31 19:30:51 EDT
Description of problem:
OpenMPI automatically detects when it is running under SGE (aka gridengine) and uses qrsh to launch remote tasks rather than ssh. This integration is broken in 1.5.3 as included in 6.2.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Launch an OpenMPI-1.5.3 program using SGE
OpenMPI attemts to use ssh
OpenMPI uses qrsh
Upstream claims this was fixed in 1.5.4. See <https://svn.open-mpi.org/trac/ompi/ticket/2763>.
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
It looks like this should be fixed by the OpenMPI upgrade in Red Hat Enterprise Linux 6.3. Can you test the 6.3 beta version and report whether this is still broken?
That version does indeed fix it -- thanks!
