[Seminar] Towards to Power Constrained High Performance Computing
■호스트: 유승주 교수 (x9392, 02-880-9392)
This talk discusses challenges for designing green supercomputers, and introduces research results to measure and manage power consumption of high performance machines. Power consumption is expected to be a first class design constraint for developing post peta-scale supercomputers. The goal of our research is to realize a post peta-scale high-performance computing environment with making effective use of a limited power budget. First, in this talk, power-performance prediction techniques of large-scale interconnection network that is a key component of state-of-the-art supercomputers are introduced. Then we discuss power variation issue in power-constrained super computing and propose a novel variation-aware power budgeting scheme to maximize effective application performance.
