get the following error when I attempt to run an mpi program (called "first", in this case) across several nodes (it works on a single node):
$ mpirun -np 3 --hostfile /tmp/nodes ./first ./first: error while loading shared libraries: libmpi.so.0: cannot open shared object file: No such file or directory My library path looks okay and I am able to run other programs, including listing the supposedly missing library: $ echo $LD_LIBRARY_PATH /opt/openmpi/1.1/lib/ $ mpirun -np 3 --hostfile /tmp/nodes uptime 16:42:51 up 22 days, 3:14, 10 users, load average: 0.01, 0.02, 0.04 19:49:32 up 1:36, 0 users, load average: 0.00, 0.00, 0.00 19:40:01 up 1:37, 0 users, load average: 0.00, 0.00, 0.00 $ mpirun -np 3 --hostfile /tmp/nodes ls -l /opt/openmpi/1.1/lib/libmpi.so* lrwxrwxrwx 1 root root 15 Jul 13 15:44 /opt/openmpi/1.1/lib/libmpi.so -> libmpi.so.0.0.0 lrwxrwxrwx 1 root root 15 Jul 13 15:44 /opt/openmpi/1.1/lib/libmpi.so.0 -> libmpi.so.0.0.0 -rwxr-xr-x 1 root root 6157698 Jul 12 18:08 /opt/openmpi/1.1/lib/libmpi.so.0.0.0 lrwxrwxrwx 1 root root 15 Jul 26 16:17 /opt/openmpi/1.1/lib/libmpi.so -> libmpi.so.0.0.0 lrwxrwxrwx 1 root root 15 Jul 26 16:17 /opt/openmpi/1.1/lib/libmpi.so.0 -> libmpi.so.0.0.0 -rwxr-xr-x 1 root root 6157698 Jul 12 18:08 /opt/openmpi/1.1/lib/libmpi.so.0.0.0 lrwxrwxrwx 1 root root 15 Jul 26 13:50 /opt/openmpi/1.1/lib/libmpi.so -> libmpi.so.0.0.0 lrwxrwxrwx 1 root root 15 Jul 26 13:50 /opt/openmpi/1.1/lib/libmpi.so.0 -> libmpi.so.0.0.0 -rwxr-xr-x 1 root root 6157698 Jul 12 18:08 /opt/openmpi/1.1/lib/libmpi.so.0.0.0 Any suggestions?
