[mvapich-discuss] OFA-IB-CH3 vs. OFA-IB-Nemesis

[Mark Dixon]

Hi,

I've been playing with the (relatively) recent support for OFA-IB-Nemesis 
in MVAPICH2 1.5.1p1. It seems to be giving some pretty good performance 
figures for IMB/PALLAS on our Linux OFED 1.4.1 cluster compared with 
MVAPICH2 1.4.

Looking at the documentation, I notice that OFA-IB-CH3 (section 4.4) is 
still built by default, not OFA-IB-Nemesis (section 4.5).

Is OFA-IB-CH3 recommended over OFA-IB-Nemesis?

Thanks,

Mark
