Theoretically using the OFED stack with a supporting card (E.G. Myrinet 10GbE) then you should be able to leverage RDMA.
That said, I've not tried it yet.  It's on my list of things to R&D.

OFED/ROCE/iWARP:

Do you all use IB?

Has anyone tried RDMA over 10G via the OFED stack?


Most of our customers we use RDMA over verbs

Is this the same thing you mentioned  a few weeks ago with respect to ROCE. Does gpfs even support this?
