In the original case of 7 nodes and processes if we do -binding pe linear:2,

those processes bound to different cores on the same machine.
Can we get a full output of such a run with -report-bindings turned on. I
think we should find out that things actually are happening correctly except
for the fact that the 6 of the nodes have 2 cores allocated but only one is
being bound to by a process.
Sure. Here's the stderr of a job submitted to my cluster with 'qsub -pe mpi 8
-binding linear:2 myScript.com' where myScript.com runs 'mpirun -mca
ras_gridengine_verbose 100 --report-bindings ./unterm':

Is that all that came out? I would have expected a some output from
each process after the orted forked the processes but before the exec of
unterm.
