[mvapich-discuss] Errors spawning processes with mpirun_rsh

[Jaidev Sridhar]

Hi Rafael,

The message indicates that the application terminated  with a non zero 
error code or crashed after launching. Can you check if it leaves any 
core files? You may need to set ulimit to  unlimited. For example, add 
ulimit -c unlimited in your ~/.bashrc.

Can you also give us details of the cluster and any options you've 
enabled with MVAPICH / MVAPICH2?
