I used "mpicc cpi.c -o cpi.exe" to compile and then run the code with "mpiexec -f hostfile -n 4 cpi.exe", it's still the same problem. It hangs there. <br><br>I'm wondering if you had chance to look at my c.txt and m.txt. Is it possible that my compilation is actually not completely successful? Thanks!<br>

Run the cpi example in the examples directory (not the one in the f90 directory).<br>

I'm guessing that it's probably a communication problem. Like in the previous version of MPICH2, I need mpdboot to set up a parallel environment first. But, I have no idea how to check this. I found I don't have mpdboot common in my installation.<br>
