If you’ve been following this publication even casually for the past four years or so, I’m sure you realize that a lot of digital ink has been spilled about the ascent of GPUs in high performance computing. This week was no exception. Part of this interest is due to the fact that, as HPC goes, GPU computing is one of the industry’s more exciting topics. After all, major processor transitions in supercomputing only occur once every 20 years or so, and we seem to be in one of them now.

This tends to happens as new chips promising better performance per dollar come to the fore. The fact the GPUs can also deliver superior performance per watt is especially relevant now, given that post-petascale computing will require much more energy-efficient processing than that afforded by traditional CPUs.
