[mpich-discuss] Could not resolve hostname

[Guo, Yanfei]

Hi Fa-Gung,

This looks like your network is not correctly configured. The problem is likely to be the /etc/hosts file.

Also, I would suggest you to try the latest stable version of MPICH (v3.2). The MPICH-2 v1.4.1 is a very old version.

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.
