[mpich-discuss] job in node

[Pavan Balaji]

You seem to have installed MPICH2 in /usr/local/bin, not your home directory. Here's the error you reported that shows that:

> [root at ranjit mpich2-1.3.1]# mpiexec -hosts ranjit,node01 -n 5
> ./examples/cpi
> bash: /usr/local/bin/hydra_pmi_proxy: No such file or directory

Is this directory shared through NFS? If not, you need to install MPICH2 in your home directory. The MPICH2 README has information on how to do this (step 4 specifically). Did you follow those instructions?
