I'm trying to setup a small cluster of 2 nodes. Both nodes are running Fedora 11 Kernel 2.6.29.4, have the same user mpiuser with the same password. Both of them have their env vars set as follows in /etc/profile itself: PATH usr/lib/openmpi/bin LD_LIBRARY_PATH usr/lib/openmpi/lib
Currently, mpirun executes successfully on either node individually. However, when trying to run over the network, I get: [mpiuser@c-199 ~]$ mpirun -np 3 --hostfile .mpi_hostfile ./a.out bash: orted: command not found -------------------------------------------------------------------------- A daemon (pid 12639) died unexpectedly with status 127 while attempting to launch so we are aborting. There may be more information reported by the environment (see above). This may be because the daemon was unable to find all the needed shared libraries on the remote node. You may set your LD_LIBRARY_PATH to have the location of the shared libraries on the remote nodes and this will automatically be forwarded to the remote nodes. -------------------------------------------------------------------------- -------------------------------------------------------------------------- mpirun noticed that the job aborted, but has no info as to the process that caused that situation. -------------------------------------------------------------------------- mpirun: clean termination accomplished What fixes should I try to get the cluster to work?
