I thought I would point you to some exciting work students are participating in over at Texas Advanced Computing Center.  TACC is mentoring several University of Texas at Austin students in the SC10 Student Cluster Competition to be held this November in New Orleans.  This is great work that the students are doing, and it is great to see involvement from TACC and support from the HPC community.  Here are some brief details of the SC10 challenge to build a system within the power constraints equivalent to only three coffee-makers!

The Student Cluster Competition (SCC) showcases the computational impact of clusters and open source software in the hands of motivated and sleep-deprived students under both a time and power constraint. Uh, no pressure…

During SC10, teams consisting of six students… will compete in real-time on the exhibit floor to run a workload of real-world applications on clusters of their own design while never exceeding the dictated power limit.

Prior to the competition, teams work with their advisor and vendor partners to design and build a cutting-edge commercially available small cluster constrained by the 26 amps available during the conference. Teams must also learn the four open source competition applications and are encouraged to enlist the help of domain specialists.”

It is exciting to see students motivated to work on some of the challenges we face in the industry.  I first met the two student leaders of this six-person group at SC09 in Portland last year. Read the rest of this entry »


There was a recent article in IEEE Spectrum entitled The Trouble With Multicore that gives a really nice background on how multicore processors have taken hold in the computing industry.  I wrote about this article on my blog Multicore in HPC – Where will we stand in 10 years? In doing so, I offered some additional insight into the future of multicore in HPC.

Additionally, and more importantly, I posed the same question to the High Performance Computing group on LinkedIn and there has been lots of great insight posted there as well. So much so, that I thought it would be very beneficial to share some very keen insight others in the industry have shared.

Head on over to my blog at, to read some of the highlights of the great discussion going on at LinkedIn.

I was reading in a recent ACM journal a few days ago, and I came across an article entitled In Search of a Natural Gesture.  The article explores human input/output methods and devices for computing systems, and I noticed some indirect comparisons to HPC.  This quote caught my attention:

The average consumer’s demand for more powerful technology has simply not kept up with the exponentially increasing supply. Some have referred to this stall in performance demand as the era of “good enough computing.” Read the rest of this entry »

What You Should Know about Power and Performance Efficiency

I contributed to this article for the May/June issue.  Let me know what you think about the article, including the comments from others in the HPC industry.
