Pavan, i guess mpiexec -f machinefile -n 10 /bin/hostname works fine<br><br><blockquote style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;" class="gmail_quote">pexe-note@pexe-note:~$ mpiexec -f machinefile -n 10 /bin/hostname<br>

</div><br><br>but the problem with cpi example is the same (using pexe-note)...<br><br><div class="gmail_quote">2011/10/28 Pavan Balaji <span dir="ltr"><<a href="mailto:balaji@mcs.anl.gov">balaji@mcs.anl.gov</a>></span><br>

Please keep mpich-discuss cc'ed.<br>
<br>
Apart from the fact that something is wrong with pexe-note, it's hard to guess anything else from the below error message.<br>
<br>
Does a non-MPI program such as /bin/hostname work correctly?<br>
