[mpich-discuss] HP-XC 3000 cluster issues

[Gauri Kulkarni]

In the installation that we have tried here, there definitely is a folder
named bin/ that contains mpirun and mpiexec which point to mpiexec.py. I
have modified PATH so that when I issue "which mpirun" I get the mpirun in
mpich2 installation. So if I use mpirun from command line instead of bsub,
it calls the mpirun from mpich2 directory and runs correctly on one node
(with 8 procs).
