usNIC provider contributed to libfabric

October 20, 2014 at 5:54 am PST

Today’s guest post is by Reese Faucette, one of my fellow usNIC team members here at Cisco.

I’m pleased to announce that this past Friday, Cisco contributed a usNIC-based provider to libfabric, the new API in the works from OpenFabrics Interfaces Working Group.

(Editor’s note: I’ve blogged about libfabric before)

Yes, the road is littered with the bodies of APIs that were great ideas at the time (or not), but that doesn’t change the fact neither Berkeley sockets nor Linux Verbs are really adequate as cross-vendor, high-performance programming APIs.

HPC over UDP

September 12, 2014 at 9:52 am PST

A few months ago, I posted an entry entitled “HPC in L3“.  My only point for that entry was to remove the “HPC in L3? That’s a terrible idea!” knee-jerk reaction that us old-timer HPC types have.

I mention this because we released a free software update a few days ago for the Cisco usNIC product that enables usNIC traffic to flow across UDP (vs. raw L2 frames).  Woo hoo!

That’s right, sports fans: another free software update to make usNIC even better than ever.  Especially across 40Gb interfaces!

MPI over 40Gb Ethernet

May 10, 2014 at 3:29 am PST

Half-round-trip ping-pong latency may be the first metric that everyone looks at with MPI in HPC, but bandwidth is one of the next metrics examined.

40Gbps Ethernet has been available for switch-to-switch links for quite a while, and 40Gbps NICs are starting to make their way down to the host.

How does MPI perform with a 40Gbps NIC?

sc13-logo_0Are you going to be in Denver at SC’13 next week?

Good!

You need to stop by the Cisco booth (#2535) and say hi to your friendly neighborhood Open MPI developers: Dave Goodell, Reese Faucette, and Jeff Squyres.

Lawrence Berkeley Labs talk: Cisco Userspace NIC (usNIC)

November 8, 2013 at 11:58 am PST

Here’s the slides from my second talk, which is a deep technical dive into both how the usNIC technology works, and how we use that technology in the BTL plugin that we wrote for Open MPI (which is upstream starting with Open MPI v1.7.3).
