Hi,<br>
<br>
So I have applied the changes but I get the following behavior:<br>
<ul>
<li>when machine name is numeric only, things work</li>
<li>when machine name is numeric and dots, things work<br>
</li>
<li>when machine name is a valid hostname, things work (I did this
just to debug this problem)<br>
</li>
<li>when machine name is not a valid hostname, I get (for a 2 task
job):</li>
</ul>

Does mpich2 use the machine entries for something other than
launching and which might be causing a problem here? If yes, where
can I look to see what is up?<br>
<br>
Thanks,<br>
