[mpich-discuss] Does MPICH2 work with multiple NICs, and how?

[Darius Buntinas]

Unfortunately, I don't think there's anything in the documentation on 
that (but there should be).  And I'm not aware of any evaluations of 
mpich2 using channel bonding.

Yes, we are looking into supporting multiple NICs directly from MPICH2.
