In order to support openmpi-1.5.3 with PSM using slurm, i have to export a variable to each rank in the pool, it generates a random key, but all tasks must have the same key. I was thinking of running as part of the job prolog, but i can't figure out how to get the environment variable exported.
You can see the below message, for openmpi support http://www.open-mpi.org/community/lists/users/2010/12/15242.php I see there is a spank plugin, called getenv, but we're not running any spank plugins at the moment, is there another way to do this?
