Thank you again for your response.
Our backbone is 1GB as far as I know, but would have to check. The bigger issue is with nodes on the WAN, we should be lucky to sustain 1MB on those lines. That means we should consider compression/decompression for the results.
I will have our administrator look into setting up NFSes on the available nodes.
Our application stack is fairly standard: FreeBSD 8.x with a C++/mysql/python application. This should eliminate the diversity problem, but that doesn't mean we will not run into hardware issues. We may even have to assign the jobs greedily to the node with the fastest CPU first.

orte-clean
orte-clean(1) Open MPI orte-clean(1)
NAME
orte-clean - Cleans up any stale processes and files leftover from Open MPI jobs.
SYNOPSIS
orte-clean [--verbose]
mpirun --pernode [--host | --hostfile file] orte-clean [--verbose]
OPTIONS
[-v | --verbose] This argument will run the command in verbose mode and print out the universes that are getting cleaned up as well as pro-
cesses that are being killed.
DESCRIPTION
orte-clean attempts to clean up any processes and files left over from Open MPI jobs that were run in the past as well as any currently
running jobs. This includes OMPI infrastructure and helper commands, any processes that were spawned as part of the job, and any temporary
files. orte-clean will only act upon processes and files that belong to the user running the orte-clean command. If run as root, it will
kill off processes belonging to any users.
When run from the command line, orte-clean will attempt to clean up the local node it is run from. When launched via mpirun, it will clean
up the nodes selected by mpirun.
EXAMPLES
Example 1: Clean up local node only.
example% orte-clean
Example 2: To clean up on a specific set of nodes specified on command line, it is recommended to use the pernode option. This will run
one orte-clean for each node.
example% mpirun --pernode --host node1,node2,node3 orte-clean
To clean up on a specific set of nodes from a file.
example% mpirun --pernode --hostfile nodes_file orte-clean
Example 3: Within a resource managed environment like N1GE, SLURM, or Torque. The following example is from N1GE.
First, we see that we have two nodes with two CPUs each.
example% qsh -pe orte 4
example% mpirun -np 4 hostname
node1
node1
node2
node2
Clean up all the nodes in the cluster.
example% mpirun --pernode orte-clean
Clean up a subset of the nodes in the cluster.
example% mpirun --pernode --host node1 orte-clean
