Try rebuilding your MPICH omitting the "--with-pmi=slurm". Instead, you can use hydra's built-in support for slurm. Some information is available here: http://wiki.mpich.org/mpich/index.php/Using_the_Hydra_Process_Manager

I can't remember exactly what will be auto detected and what won't (Pavan, can you help me out here?). You might need to set these environment variables:

HYDRA_LAUNCHER=slurm HYDRA_RMK=slurm

Then use "mpiexec" instead of "srun".

Everything is auto-detected for slurm. You don't have to set anything. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
