[R-sig-hpc] Snow Not Distributing

I have been able to successfully setup snow (0.3-5) and Rmpi (0.5-9) on 
my RedHat 5 cluster, and have it working perfectly for jobs that don't 
span multiple nodes.

We're using Torque for resource management, so I start a job with access 
to multiple nodes and load Snow. Unfortunately, not matter what size 
cluster I try to make, all of the workers end up running on the same 
host -- leaving the other hosts idle.

I'm no expert with MPI or snow, so I'm really not sure how to approach 
debugging this.

Any input would be much appreciated!
