[cam-users] Invalid combination: nodes=2, tasks_per_node=1, procs=1

[John Fasullo]

The default CAM2.0.1 also gives me the following error when executing 
from the provided run-ibm.csh script with:

## POE Environment.  Set these for interactive jobs.  They're ignored 
by LoadLeveler
## MP_NODES is the number of nodes.  The number chosen should be a 
power of 2, up to a max
  of 16 for T42.
setenv MP_NODES 2
setenv MP_TASKS_PER_NODE 1
setenv MP_EUILIB us
setenv MP_RMPOOL 1

....it compiles fine but upon running (on blackforest or babyblue) 
gives:
