Hi Ralph,
I quickly tried 2 runs:
mpirun -report-bindings -bind-to core Myprog
mpirun -machinefile pbs_hosts -np ${NPROCS} -report-bindings -bind-to core
Myprog
It works fine in both cases on node03 and node08.

problem in the LAMA mapper. If not, then it is likely a problem in a
different section of the code.
