The initial error was ompi could not find orted on the second node, and that was fixed by using the full path for mpirun
if you run under pbs, you should not need the hostile option. just ask pbs to allocate 2 nodes and everything should run smoothly. at first, I recommend you run a non MPI application /.../bin/mpirun hostname and then nwchem if it still does not work, then run with verbose palm and post the output Cheets, Gilles On Sunday, August 2, 2015, abhisek Mondal <abhisek.m...@gmail.com> wrote: > I'm on a HPC cluster.
