Anthony Chan,<br><br>I did not install MPICH on falcon due it to be shared by nfs, so I just installed in the server and I get an image of this in both computers. I have tried to execute like this "./cpi" and it gets the same error. I can process both alone in each computer, but when I want it done by both this message returns to me. Any idea?<br>
<br>Thanks a lot for your attention,<br><br>Ari<br><br><div class="gmail_quote">2008/6/30 Anthony Chan <<a href="mailto:chan@mcs.anl.gov">chan@mcs.anl.gov</a>>:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Is mpich2 installed on falcon ? If so, is it installed in the same<br>
location as eagle ?<br>
<br>
Assuming you have mpich2 installed correctly on both machines,<br>
cd to <mpich2-install-dir>/examples, then do<br>
<br>
mpiexec -n 10 ./cpi<br>
