Hi Adrian - Thanks for the reply. I have been investigating this further. It appears that ssh isn't starting my .zshrc file. This is strange.
If I execute
ssh host-0 export
I get only a minimal set of environment variables. One of them is SHELL = /bin/zsh. There is no LD_LIBRARY_PATH in the list. If I ssh into host-0 and type "export", I get my full list of variables. Seeing as how this is almost certainly an ssh problem, I should probably take this to the openssh mailing list. Thanks, Brian On 1/17/07, Adrian Knoth <a...@drcomp.erfurt.thur.de> wrote:

Even more, they need to be found in a system library dir (e.g. /usr/lib) or somewhere inside LD_LIBRARY_PATH. I guess you already know that. > If I run the following, however, I see that my LD_LIBRARY_PATH is correct: > > mpirun -np 1 -host burn-0 echo $LD_LIBRARY_PATH The variable is expanded on the calling host: adi@ipc654:~$ echo $HOSTNAME ipc654 adi@ipc654:~$ mpirun -np 1 -host amun3 echo $HOSTNAME ipc654 In other words: you're echoing your local LD_LIBRARY_PATH. If this should be the same on host-1, either set it in your login scripts (on host-1) or export it with -x: host-0:~$ mpirun -x LD_LIBRARY_PATH -host host-1 your_prog HTH -- Cluster and Metacomputing Working Group Friedrich-Schiller-Universität Jena, Germany private: http://adi.thur.de _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
