Hi TIm thanks for the suggestions. I now set both paths in .zshenv but it seems that LD_LIBRARY_PATH still does not get set. The ldd experment shows that all openmpi libraries are not found, and indeed the printenv shows that PATH is there but LD_LIBRARY_PATH is not.
It is rather unclear why this happens... As to thew second problem: $ mpirun --debug-daemons -np 2 --prefix /opt/openmpi --host nano_02 ./MPI2Test2 [aim-nano_02:05455] [0,0,1]-[0,0,0] mca_oob_tcp_peer_try_connect: connect to 130.60.49.134:40618 failed: Software caused connection abort (103) [aim-nano_02:05455] [0,0,1]-[0,0,0] mca_oob_tcp_peer_try_connect: connect to 130.60.49.134:40618 failed, connecting over all interfaces failed!

I also made sure that nano_02 cann ssh to plankton without password, but that didn't change the output. Does this message give any hints as to the problem?
