Description Joshua Baker-LePain 2012-02-09 23:19:34 UTC

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>.

Comment 2 RHEL Program Management 2012-05-03 05:35:43 UTC

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.

Comment 3 Jay Fenlason 2012-06-04 19:06:53 UTC

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?

Comment 4 Joshua Baker-LePain 2012-06-05 20:36:42 UTC

That version does indeed fix it -- thanks!
