Thank you Sir the problem was with the paths of 'bin' and 'lib' folders so i used de *mpirun --prefix* command. I want to run a program 'pi' now using the cluster, so where do i place de file on de master and the compute nodes?
Also how do i come to know that the program is using resources of both the nodes? On Sat, Apr 4, 2009 at 7:05 PM, Jeff Squyres <jsquy...@cisco.com> wrote: > It might be best to: > > 1.
