[mpich-discuss] how to use ifhn in machinefile in mpich2-1.3.2?

[Limin Gu]

Hi All,

mpich2-1.3.2 is configured and built with default options.

I have a machine file like this:

n0 ifhn=172.20.20.100
n1 ifhn=172.20.20.101

but mpiexec would not take ifhn as a valid token. What did I do wrong? Do I
need to turn on some specific configure option and rebuild?

Thank you for your help!
