[mpich-discuss] mpich2 and IPoIB

[Fabio Motezuki]

Returning, I compiled de 1.0.8rc1 source and using mpd the ifhn in the 
mpd.hosts file worked well, but not with interface name resolution, just 
using ip directly.

In 1.0.7 I tried to use ifhn in the machinefile for smpd execution, but 
no effect even when using the ip address of the infiniband interface.
