ARM In Supercomputers — 'Get Ready For the Change'

[wraggster]

Commodity ARM CPUs are poised to to replace x86 CPUs (http://www.pcworld.com/article/2039798/smartphone-chips-could-replace-server-processors-in-hpc-researchers-say.html) in modern supercomputers just as commodity x86 CPUs replaced vector CPUs in early supercomputers. An analysis by the EU Mountblanc Project (http://www.montblanc-project.eu/sites/default/files/publications/Are%20mobile%20processors%20ready%20for%20HPC.pdf) (PDF) (using Nvidia Tegra 2/3, Samsung Exynos 5 & Intel Core i7 CPUs) highlights the suitability and energy efficiency of ARM-based solutions. They finish off by saying, 'Current limitations [are] due to target market condition — not real technological challenges. ... A whole set of ARM server chips is coming — solving most of the limitations identified.
