Hi Aurora,
it seems that there is some confusion in your installation
or in your
environment variables: you declare that you are running
mpich, which is
another MPI implementation, while this mailing list concerns
LAM-MPI
implementation of MPI, and at the same time your error is
related to a
pathname containing the word 'lam'. Both mpich and LAM-MPI
use the
command mpirun, so you should make sure that the one you use
(try the
command 'which mpirun') comes form the wanted package.
I do not know rocks cluster package, but I can guess that
either your
mpirun command/script or your mpi-executable are trying to
execute the
command 'env /opt/lam/gnu/lib' and /opt/lam/gnu/lib is a
directory while
in that place there should be the name of an executable
file.
Hope this helps, Davide
