April 8, 2013 at 6:25 am PST

In a prior blog post, I talked about latency analogies.  I compared levels of latencies to your home, your neighborhood, a far-away neighborhood, and another city.  I talked about these localities in terms of communication.

Let’s extend that analogy to talk about data locality.

I CAN HAS MPI

April 1, 2013 at 5:01 am PST

The Cisco and Microsoft joint Cross-Animal Technology Project, a well-established player in the field of multi-species collaborative initiatives, is pleased to introduce its next project: a revolution in High Performance Computing (HPC): LOLCODE language bindings for the Message Passing Interface (MPI).

CATP believes that cats are natural predatory programmers.  Who better to take advantage of all the world’s spare, unused computing cycles than cats?  They’re at home when we’re not.  They’re clever, they can problem-solve, and they have lots of free time on their… paws.

Latency Analogies

March 31, 2013 at 6:00 am PST

Multiple readers have told me that it is difficult for them to understand and/or visualize the effects of latency on their HPC applications, particularly in modern NUMA (non-uniform memory access) and NUNA (non-uniform network access) environments.

Let’s breaks down the different levels of latency in a typical modern server and network computing environments.
