Hello, I am building a cluster with 6 Apple xserve running OSX Server 10.6 :
node1.cluster node2.cluster node3.cluster node4.cluster node5.cluster node6.cluster I've intalled openmpi in directory /opt/openmpi-1.4.2 of node1 then I made a share point of /opt -> /Network/opt and define variables export MPI_HOME=/Network/opt/openmpi-1.4.2 export OPAL_PREFIX=/Network/opt/openmpi-1.4.2 I can access to openmpi from all nodes. However, I still face a problem when I launch a computation mpirun --prefix /Network/opt/openmpi-1.4.2 -n 4 -hostfile ~peyret/hostfile space64 -f Test/cfm56_hp_Rigid/cfm56_hp_Rigid.def -fast is returns me the error message : [node2.cluster:09163] mca: base: component_find: unable to open /Network/opt/openmpi-1.4.2/lib/openmpi/mca_odls_default: file not found (ignored) [node4.cluster:08867] mca: base: component_find: unable to open /Network/opt/openmpi-1.4.2/lib/openmpi/mca_odls_default: file not found (ignored) [node3.cluster:08880] mca: base: component_find: unable to open /Network/opt/openmpi-1.4.2/lib/openmpi/mca_odls_default: file not found (ignored) any idea ?
