I need to change system wide how OpenMPI launch the jobs on the nodes of my
cluster.
Setting:
export OMPI_MCA_plm_rsh_agent=oarsh
works fine but I would like this config to be the default with OpenMPI. I've
read several threads (discussions, FAQ) about this but none of the provided
solutions seams to work.
I have two files:
/usr/lib/openmpi/1.4-gcc/etc/openmpi-mca-params.conf
/usr/lib64/openmpi/1.4-gcc/etc/openmpi-mca-params.conf
In these files I've set various flavor of the syntax (only one at a time, and
the same in each file of course!):
test 1) plm_rsh_agent = oarsh
test 2) pls_rsh_agent = oarsh
test 3) orte_rsh_agent = oarsh
But each time when I run "ompi_info --param plm rsh" I get:
MCA plm: parameter "plm_rsh_agent" (current value: "ssh : rsh", data source:
default value, synonyms:
pls_rsh_agent)
The command used to launch executables on remote nodes
(typically either "ssh" or "rsh")
With the exported variable it works fine.
Any suggestion ?
The rpm package of my linux Rocks Cluster provides:
Package: Open MPI root@build-x86-64 Distribution
Open MPI: 1.4.3
Open MPI SVN revision: r23834
Open MPI release date: Oct 05, 2010
Thanks
