MPICH2 needs to be present on all the nodes in the same location. Looks 
like MPICH2 is not present on node01. If you have an NFS server, it 
might be easier to install MPICH2 on the NFS shared directory, so all 
nodes can see it.

No space between "ranjit," and "node01". Otherwise, mpiexec will think 
that "node01" is the next argument.
