Hello all,
Open MPI 1.3 is installed on Rocks 4.3 Linux cluster with support of
SGE i.e using --with-sge.
But the ompi_info shows only one component:
# /opt/mpi/openmpi/1.3/intel/bin/ompi_info | grep gridengine
MCA ras: gridengine (MCA v2.0, API v2.0, Component
v1.3)
Is this right? Because during ompi installation SGE qmaster daemon
was
not working.
Now the problem is, the open mpi parallel jobs submitted thru
gridengine are failing (when run on multiple nodes) with the error:
$ cat err.26.Helloworld-PRL
ssh_exchange_identification: Connection closed by remote host

A daemon (pid 8462) died unexpectedly with status 129 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
When the job runs on single node, it runs well with producing the
output but with an error:
$ cat err.23.Helloworld-PRL

What may be the problem for this behavior?
