Hi;
Please forgive me if this is a niave newbie question. I am
trying to execute mpirun on a system that has rocks4.2.1. (I am running mpich
which came with the rocks install package) As root I can run “mpirun
–np 4 cpi” with no problems, however as non-root user I get the
following error:
env: /opt/lam/gnu/lib: Permission denied
I have changed the permissions of the /opt/lam/gnu/lib
directory on both the front end and the compute node (/opt is not cross mounted
across compute nodes) so that the non-root user is the owner of the
directory…however this had absolutely no effect on the error. I have also
opened the entire directory to all r and x privileges.
Any advice you may have would be most welcome – thanks
in advance!
Regards;
