GPU Processing: What Gives?

I call it a PCU not a GPGPU

In case you have been hard at work on your latest breakthrough, there has been some news on the GPU processing front. What is GPU processing and why should I care you ask? The idea is rather interesting. Drawing pixels on screens is a parallel problem. Video card manufactures have taken advantage of this by placing many parallel graphics processors on their video chips. Current generation video chips now use General Purpose (GP) processors for this task. The "general purpose" feature means that graphics hardware can be now be used for parallel (predictable) computing problems. (i.e. an array multiplication is a predictable operation). You can find more background by consulting the article Pixels to PetaFLOPS: How GPUs are Pushing the HPC Envelope and (General Purpose Graphical Processing Units). By the way, that is too many G's and P's for me. I like to think of it as heterogeneous computing or simply a Parallel Computing Unit (PCU). As an HPC geek, I like to think of it as PCU that can also do video, but in reality it is the other way around. We have the gamers to thank. So a big thank-you to those useless gamer types that everybody complains about. Keep playing (and buying) games and hardware. You are helping to subsidize the cure for all the ailments you will suffer from not going outside in your youth.

MPI-Tube: Learn MPI the Internet Way

Over the past year or two, I have been slowly creating a large set of Open MPI training material that I've used to present to my company's customers and partners. I have just recently received permission to release video presentations of all of my slides to the greater HPC community. Woo hoo!

Intermediate Beowulf Administration and Optimization

Could there be a more shameless plug?

Back by popular demand, the ARC at Georgetown University has for some strange reason decided to offer my Intermediate Beowulf Administration and Optimization course for a second time this March (18th-20th). The details and background are on the ARC HPC Training Page. Class size is limited, so if you have interest, sign up early. Course description is below. Excellent donuts.

Need a (High Performance) HUG

If you live in the New York City Metropolitan area, you may be interested in attending the first NYCA-HUG, which is short for the New York City Area HPC Users Group. We will be kicking off our first meeting on Thursday November 1 (Updated) Le Figaro Cafe in Greenwich Village at 7PM. You can find more information here.

And while you are clicking around, check out Today's HPC Clusters. Cluster content, White papers, Webinars, and more, all good stuff. And while you are at there, sign up for the newsletter and you get to read my weekly HPC rants. A free opinion, what a bargain.

InfiniBand for the Masses

From the "I'll take eight department"

The Linux cluster world is moving towards InfiniBand for many reasons: bandwidth, latency, message rate, N/2, price/performance, and other factors that affect performance and price. But usually it's focused on larger systems, many times greater 64 nodes up to multiple thousand nodes. At that same time the reasons for moving to InfiniBand are still valid for smaller clusters, particularly performance, but the economics are not. Basically InfiniBand is just too expensive for smaller systems and usually does not make sense from a price/performance perspective. But that has just changed...
