Hi,

I installed mpich2-1.4.1p1 on CentOS 6.9 following the README instruction.  Configure, make, and make install steps went fine.  But, when running CPI example on local machine, I got:

$ pwd
/home/ffan/Downloads/mpich2-1.4.1p1

$ mpiexec -n 2 ./examples/cpi
ssh: Could not resolve hostname CentOS-6.localdomain: Name or service not known

What could have been wrong?  Thank you very much for your help.
