Dr. Michele Weiland, ADEPT Project, Edinburgh Parallel Computing Centre, UK
The focus of the HPC community is firmly on reaching its next big goal: the Exascale. There are many technical hurdles that need to be overcome to reach this goal in the next five to ten years, but there is an underlying theme of efficiency. HPC applications often only use a few percent of the peak performance a system can offer, wasting vast amounts of resources that could be exploited to achieve increased science throughput. The efficiency of Exascale systems in terms of power is also of great concern – we will need to achieve 50 GFlop/s per Watt if we want to stay within a 20MW power envelope. In this talk, I will present the work of two projects: Adept, which investigates and models power/energy expenditure in parallel systems; and NEXTGenIO, which exploits Intel 3D XPoint technology to eliminate the I/O bottleneck in large-scale parallel systems.
