Description of problem: In example file /usr/share/doc/condor-7.6.5/examples/openmpiscript on RHEL 6.2 is used parameter 'plm_rsh_agent' which is deprecated on used version of openmpi. Version-Release number of selected component (if applicable): - RHEL 6.2 # rpm -qa | grep condor condor-classads-7.6.5-0.11.el6.i686 condor-7.6.5-0.11.el6.i686 # rpm -qa | grep openmpi openmpi-1.5.3-3.el6.i686 openmpi-devel-1.5.3-3.el6.i686 How reproducible: 100% Steps to Reproduce: 1. Run parallel openmpi job with openmpiscript from examples mentioned above (see Bug 759433, comment 2). 2. Check error output file. Actual results (with set -x): + mpirun -v --mca plm_rsh_agent /usr/libexec/condor/condor_ssh -n 1 -hostfile machines summpi -------------------------------------------------------------------------- A deprecated MCA parameter value was specified in the environment or on the command line. Deprecated MCA parameters should be avoided; they may disappear in future releases. Deprecated parameter: plm_rsh_agent -------------------------------------------------------------------------- -------------------------------------------------------------------------- A deprecated MCA parameter value was specified in the environment or on the command line. Deprecated MCA parameters should be avoided; they may disappear in future releases. Deprecated parameter: plm_rsh_agent -------------------------------------------------------------------------- + sshd_cleanup Expected results: No warning ebout depreaced MCA parameter. Additional info: Used argument for --mca parameter probably should be 'orte_rsh_agent' (according to http://www.open-mpi.org/faq/?category=rsh).
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: C: Run a openmpi job with the openmpiscript provided with condor. C: During the job run, stderr would show that the script is using a deprecated parameters. F: Update the openmpiscript to no longer use the deprecated parameters. R: stderr should be empty for a normal run.
Tested on RHEL 6.4 - i386/x86_64 with: # rpm -q condor selinux-policy openmpi condor-7.8.8-0.3.el6.x86_64 selinux-policy-3.7.19-192.el6.noarch openmpi-1.5.4-1.el6.x86_64 No warnings about deprecated MCA parameter in error log. >>> VERIFIED
