The error in the 5th step is caused by a chatty login message. This makes
mpi complain but it ought to work anyway.<br>
You want to turn off motd, and if using freebsd create a file called ".huslogin"
and put it in the users home directory.<br>
<br>
The next error is to do with paths to mpich and to the program being launched.<br>
All the nodes need to be able to "see" the mpi binaries and need to be able
to see the executable program.<br>
The paths to mpi and the program being launched need to be the same for all
nodes and for the root node.<br>
Make sure the path is seutup properly in the environment. You may need to
chek your mount points and setup NFS properly.<br>
<br>
<br>
The last one probably has to do with name resolution.<br>
The root node usually won't need to be in the machines.linux file, but all
other nodes need to be.<br>
I believe you need to list machines by hostname, not ip addresses so be sure
that both machines have the same hostfile, same .rhosts, etc.<br>

The next message indicates that the path to the executable "mpichfoo" was
not found. <br>
