libfabric support of usNIC in Open MPI

November 17, 2014 at 8:00 am PST

I’ve previously written about libfabric.  Here’s some highlights:

Today, we’re pleased to announce the next step in our libfabric journey: my team at Cisco (the UCS product team) is contributing an open source plugin to Open MPI that uses the libfabric APIs.

usNIC support for the Intel MPI Library

November 17, 2014 at 7:00 am PST

Intel MPI LibraryCisco is pleased to announce the intention to support the Intel MPI Library™ with usNIC on the UCS server and Nexus switches product lines over the ultra low latency Ethernet and routable IP transports, at both 10GE and 40GE speeds.

usNIC will be enabled by a simple library plugin to the uDAPL framework included in enterprise Linux distributions. The Intel MPI Library can utilize the usNIC uDAPL library plugin without any modifications to existing MPI applications.

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?
