What is the output of "uname -a" on your machine? --Junchao Zhang On Wed, May 21, 2014 at 8:05 PM, Yida Wang <[email protected]> wrote:

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?

Thanks, YW
