[mvapich-discuss] mvapich2 and MPI subjobs

[James R. Leek]

I've gotten the below, more informative error message a couple of times, 
and now get it regularly.  Perhaps someone knows what it means?  All 
I've found from googling it is the code it comes from.

[leek2 mpitest2]$ mpiexec -np 1 ./mpilaunch $PBS_NODEFILE

PBS_NODEFILE: /var/spool/PBS/aux/385337.madm2
