QLogic MPI Troubleshooting
IB6054601-00 H D-29
A
The following indicates an unknown host:
$ mpirun -np 2 -m ~/tmp/q mpi_latency 100 100
MPIRUN: Cannot obtain IP address of <nodename>: Unknown host
<nodename> 15:35_~.1019
The following indicates that there is no route to a valid host:
$ mpirun -np 2 -m ~/tmp/q mpi_latency 100 100
ssh: connect to host <nodename> port 22: No route to host
MPIRUN: Some node programs ended prematurely without connecting to
mpirun.
MPIRUN: No connection received from 1 node process on node
<nodename>
The following indicates that there is no route to any host:
$ mpirun -np 2 -m ~/tmp/q mpi_latency 100 100
ssh: connect to host <nodename> port 22: No route to host
ssh: connect to host <nodename> port 22: No route to host
MPIRUN: All node programs ended prematurely without connecting to
mpirun.
The following indicates that node jobs have started, but one host could not
connect back to mpirun:
$ mpirun -np 2 -m ~/tmp/q mpi_latency 100 100
9139.psc_skt_connect: Error connecting to socket: No route to host
<nodename>.<rank> Cannot connect to spawner on host %s port %d
within 60 seconds.
MPIRUN: Some node programs ended prematurely without connecting to
mpirun.
MPIRUN: No connection received from 1 node process on node
<nodename>
The following indicates that node jobs have started, but both hosts could not
connect back to mpirun:
$ mpirun -np 2 -m ~/tmp/q mpi_latency 100 100
9158.psc_skt_connect: Error connecting to socket: No route to host
<nodename>.<rank> Cannot connect to spawner on host %s port %d
within 60 seconds.
6083.psc_skt_connect: Error connecting to socket: No route to host
<nodename>.<rank> Cannot connect to spawner on host %s port %d
within 60 seconds.
MPIRUN: All node programs ended prematurely without connecting to
mpirun.
$ mpirun -np 2 -m ~/tmp/q mpi_latency 1000000 1000000
MPIRUN: <nodename> node program unexpectedly quit: Exiting.
