[mpich2-dev] mpdboot trouble,pls help me,thanks a lot

[秦洪全]

Hi,
i have a cluster with 2 eth netwoks.one is for manage the cluster,the other
is for computing.so i need to start the mpd with the computing eth networks.
for example,i have two computer,named:c0101,c0102
/etc/hosts:
          192.168.1.1   c0101
          192.168.1.2   c0102
          10.10.1.1       g0101
          10.10.1.2       g0102
/root/.rhosts:
          c0101
          c0102
          g0101
          g0102
/root/hosts:
          c0101:8
          c0102:8
/root/ghosts:
          g0101:8
          g0102:8
i can start mpd with mpdboot:mpdboot -n 2 -f /root/hosts -r rsh,but i can
not start a job with:mpiexec -machinefile /root/ghosts -np 16 /root/cpi.

when i want to start mpd with:mpdboot -n 2 -f /root/ghosts -r rsh,report:
invalid machine names.but i really need to start my job with computing eth
network,so what do i need to write in /root/ghosts?
ps: i could not rename my computer.
