[gpfsug-discuss] HPC people - interconnects

[Jez Tucker]

Here's the stack:

https://www.openfabrics.org/resources/ofed-for-linux-ofed-for-windows/ofed-overview.html

VERBS is supported over 10GbE.  It should work if OFED VERBS == IBM VERBS.

It's verbs support you need - not sure where OFED is up to with verbs over 10G, if that's even on the cards

Cheers,

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?
