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.<div class="im">

No space between "ranjit," and "node01". Otherwise, mpiexec will think that "node01" is the next argument.<div><div></div><div class="h5"><br>
