Hi Guys,

I just finished installing mpich. But when I tried to run it, it returned
"cannot execute binary file". I double checked the file type by "file
mpiexec.hydra", which got "mpiexec.hydra: ELF 64-bit LSB executable,
version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux
2.6.16, not stripped". I am running 64-bit CentOS.

Any ideas of this error?
