Abhisek -- You are having two problems:
1. In the first "orted not found" problem, Open MPI was not finding its "orted" helper executable on the remote nodes in your cluster. When you "module load ..." something, it just loads the relevant PATH / LD_LIBRARY_PATH / etc. on the local node; it doesn't do anything for the remote nodes on which you execute. Gilles suggested a good workaround: use the full path name to Open MPI's mpirun. This tells Open MPI "hey, please be sure to load up the PATH / LD_LIBRARY_PATH with the Right Stuff to find Open MPI's executables on the remote nodes." 2. The second problem is that Open MPI is not finding the nwchem executable on at least the specified node in your cluster (i.e., cx934). Perhaps something is wrong with the network filesystem on cx934...? You might want to login to that node interactively and check. > On Aug 2, 2015, at 7:32 AM, abhisek Mondal <abhisek.m...@gmail.com> wrote: > > HI, > I have tried using full paths for both of them.
