A performance and energy analysis of I/O management approaches for exascale systems
Orçun Yildiz, Matthieu Dorier, Shadi Ibrahim, Gabriel Antoniu · 2014
The advent of fast, unprecedentedly scalable, yet energy-hungry exascale supercomputers poses a major challenge consisting in sustaining a high performance per watt ratio. While much recent work has explored new approaches to I/O management, aiming to reduce the I/O performance bottleneck exhibited by HPC applications (and hence to improve application performance), there is comparatively little work investigating the impact of I/O management approaches on energy consumption.
