Hi All,<br>
<br>
mpich2-1.3.2 is configured and built with default options.<br>
<br>
I have a machine file like this:<br>
<br>
n0 ifhn=172.20.20.100<br>
n1 ifhn=172.20.20.101<br>

<br></div>
You can just create the machinefile as:<br>
<br>
172.20.20.100<br>
172.20.20.101<br></blockquote><div><br>I tried to have just the ip address, it didn't work. <br><br>[root@flatline examples]# mpiexec -f machinefile -n 2 ./cpi<br>Invalid node specification "172.20.20.100"<br>
