Anthony,<br><br>Changing all compilers to the "_r" version makes the difference. Now I can compile my Pi.f90 with no problem! Thank you very much!<br><br>Now the problem is that when I run the code using "mpiexec -f hostfile -n 4 Pi.x", there is nothing output. It looks like a hang there. I have attached all c.txt, m.txt, mi.txt and config.log files in case you may need them for diagnosis.<br>
<br>Thanks again!<br><br><br><div class="gmail_quote">On Wed, Mar 7, 2012 at 10:45 AM, Anthony Chan <span dir="ltr"><<a href="mailto:chan@mcs.anl.gov">chan@mcs.anl.gov</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Send us your configure and make output files as stated in README.<br>
Did you try build mpich2 with _r version of compilers ?<br>
