Subject: unable to start all procs


Hi Dear 

I installed the mpich2-1.0.8 in a cluster with 30 node,
but when I use mpirun command for parallel run of WRF model such as fallow :
[hamzelou at rserver run]$ mpirun -np 20 ./wrf.exe
the all of 20 prossesser go on rserver while it have only 5 prossesser,
then I used machinfile option 
[hamzelou at rserver run]$ mpirun -machinefile /home/hamzelou/hamzehlou/machine20 -np 20 ./wrf..exe 
mpiexec: unable to start all procs; may have invalid machine names
    remaining specified hosts:
        172.17.30.1 (rnode1.research.com)
        172.17.30.4 (rnode4.research.com)
        172.17.30.2 (rnode2.research.com)
        172.17.30.3 (rnode3.research.com)

I can login with ssh on all of nodes,
I use mpdtrace command output is only 
rserever
Please help me to run it on all of nodes
Thanks
Sima
