[mvapich-discuss] mpiexec keeps erroring out. Don't know what to do

[Stecher, Fred]

Hi,
Just acquired SGI XE1300 with Intel Xeon quad core cpus. It has the SUSE
10.0 OS. Have installed MVAPICH. MPD is running on all the nodes. When I
use the following command from the head node:

mpiexec -machinefile ~/bin/noden01n02 -n 12
/home/apps/cth/cth8.1/bin/mpicth i=wh

The following error message is output:
mpiexec: unable to start all procs; may have invalid machine names
    remaining specified hosts:
        10.0.1.2 (n002)
        10.0.1.1 (n001)

If I execute the command on node n001, the following is output:
mpiexec: unable to start all procs; may have invalid machine names
    remaining specified hosts:
        10.0.1.2 (n002)

File noden01n02:
n001
n001
n001
n001
n001
n001
n002
n002
n002
n002
n002
n002

What is happening?


Thanks,

Fred
