[mvapich-discuss] QLogic with OFED verbs?

[Judicael Zounmevo]

Yep, that's what I meant; sorry my sentence was uselessly complex.
No need to check with QLogic either, I believe that :).
I actually wanted to know if on top of PSM, MVAPICH does have (optional) 
support for QLogic with OFED verbs. Is there a way for me to configure 
and run with verbs (instead of PSM) if for some reason I really need to 
use OFED verbs (instead of PSM)?
     Thanks a lot for the quick reply.
