Libfabric: Cisco’s journey, playing well with MPI

1 min read

In the previous blog entry, I shared the slides of one of the mini-talks that I gave at EuroMPI 2015 in Bordeaux, France (and don’t forget to start planning for EuroMPI 2016 in Edinburgh, Scottland). The second mini-talk I gave was twofold in itself: I discussed Cisco’s journey from the Verbs API to the Libfabric API, and […]

Libfabric paper at IEEE Hot Interconnects

Later today, Sean Hefty will present a paper about the OpenFabrics Interfaces (a.k.a. “libfabric“) at the 2015 IEEE Hot Interconnects conference. Libfabric is the next-generation Linux library being developed by an open source consortium of vendors and academic researchers that implements the OpenFabrics Interfaces, specifically designed to expose application-focused networking functionality to high performance applications (e.g., MPI, PGAS, […]

I’ve previously written about libfabric.  Here’s some highlights: libfabric is a set of next-generation, community-driven, ultra-low latency networking APIs The APIs are not tied to any particular networking hardware model Cisco is actively helping define, design, and develop the libfabric APIs as part of the community My fellow team member Reese Faucette recently contributed a […]

Top 5 Reasons the HPC Community Should Care About libfabric

2 min read

I’ve mentioned libfabric on this blog a few times: it’s a set of next-generation APIs that allow direct access to networking hardware (e.g., high-speed / low latency NICs) from Linux userspace (kernel access is in the works). To give you a little perspective: the libfabric APIs are aimed at a lower layer than MPI.  libfabric […]

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 […]

InsideHPC podcast: MPI collaboration with OpenFabrics

1 min read

In my last blog post, I described a new collaboration between the MPI community and the OpenFabrics verbs community. The collaboration started with the OpenFrameworks group asking the MPI community to list its requirements for a lower layer network API to the OpenFabrics OpenFrameworks working group. In that last blog post, I posted an abbreviated […]
