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;

Aurora
