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.

Top 5 Reasons the HPC Community Should Care About libfabric

November 12, 2014 at 10:26 am PST

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 seeks to unify and extend competing networking APIS – sockets, Linux Verbs, PSM, etc., to allow the production of extremely high performance code that is truly portable.

“…ummm, sure.  Why do I care?” you say.

I’m glad you asked!  Sean Hefty — one of the principal designers of libfabric — and I came up with this handy Top 5 list to tell you exactly why you care.

“Using Advanced MPI” book (i.e., MPI-3 for the rest of us)

November 9, 2014 at 12:50 pm PST

I’m stealing this text directly from Torsten Hoefler‘s blog, because I think it’s directly relevant to many of this blog’s readers:

Our book on “Using Advanced MPI” will appear in about a month — now it’s the time to pre-order on Amazon at a reduced price. It is released by the prestigious MIT Press, a must read for parallel computing experts.

He’s right.  Go pre-order the book now (I just did!).
