Twitter user erincollopy points us to this article at hpcprojects.com (a subsite of Scientific Computing World) on the greening of HPC
HPC suppliers are addressing this problem on a number of fronts: at the chip level, at the blade/box level, in computing infrastructure, and with software. HPC users must consider the entire ecosystem ‘from chips to chillers’ when discussing data centre optimisation with their IT managers. Power has only recently started to become such an issue. In the ‘old’ days of HPC, just a few years ago, the first two questions that vendors heard related to performance and cost, relates Ed Turkel, product marketing manager for scalable computing and infrastructure at HP. Now, the dialogue is different: for users, power, size and cooling are just as important. Given a three-year hardware lifetime, over that same period power costs can equal hardware costs.
