RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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):
openmpi-1.5.3-3

How reproducible:
Every time.

Steps to Reproduce:
1. Launch an OpenMPI-1.5.3 program using SGE
2.
3.
  
Actual results:
OpenMPI attemts to use ssh

Expected results:
OpenMPI uses qrsh

Additional info:
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!
