More Network Locality (Netloc) progress

January 31, 2014 at 9:11 am PST

We announced the Network locality project at SC’13, and generated a LOT of interest (far more than I even anticipated!).  As a refresher, here’s a link to a a blog entry we wrote about Netloc back in November.

There is still much work to be done; we’re actively continuing work in multiple areas:

The Network Locality Project (netloc)

November 18, 2013 at 5:00 am PST

Today’s guest post comes from Dr. Joshua Hursey, an Assistant Professor in the Computer Science Department at the University of Wisconsin, La Crosse.

For a number of years, developers tuning High Performance Computing (HPC) applications and libraries have been harnessing server topology information to significantly optimize performance on servers with increasingly complex memory hierarchies and increasing core counts.  Tools such as the Portable Hardware Locality (hwloc) project provide these applications with abstract, yet detailed, information of the single-server topology.  But that is where the topology analysis often stops — neglecting the one of the largest components of the HPC environment, namely: the network.
