Low-Power High Performance Computing
Panagiotis Kritikakos · 2011
The emerging development of computer systems to be used for HPC require a change in the architecture for processors. New design approaches and technologies need to be embraced by the HPC community for making a case for new approaches in system design for making it possible to be used for Exascale Supercomputers within the next two decades, as well as to reduce the CO2 emissions of supercomputers and scientific clusters, leading to greener computing. Power is listed as one of the most important issues and constraint for future Exascale systems. In this project we build a hybrid cluster, investigating, measuring and evaluating the performance of low-power CPUs, such as Intel Atom and ARM (Marvell 88F6281) against commodity Intel Xeon CPU that can be found within standard HPC and data-center clusters. Three main factors are considered: computational performance and efficiency, power efficiency and porting effort.
