Research Division on Supercomputing Systems


Professor Takizawa and Associate Professor Egawa presented their research results at the 27th WSSP

Professor Takizawa and Associate Professor Egawa made presentations at Workshop on Sustained Simulation Performance (WSSP) held at the Cyberscience Center on March 22 and 23.

27th WSSP (

This workshop was hosted by Tohoku University Cyberscience Center, Japan Ocean Research and Development Organization (JAMSTEC), Stuttgart University High Performance Calculation Center (HLRS) in Germany, and NEC, and JHPCN.This workshop invited researchers and supercomputer designers who are internationally active in computational science.We will exchange information on the latest research results on high performance and high efficiency large scale scientific computation, and discuss on future research and development of supercomputer. From our laboratory Professor Takizawa announced the result of code optimization using machine learning, Associate Prof. Egawa on the high energy efficiency job scheduling for the HPC system based on the execution time prediction of the job. (These outcomes summarize the results of Teng and Kawaharaba who completed master’s degree this year and finished.)

Hiroyuki Takizawa, “Towards prediction of effective optimizations in performance engineering.”

Ryusuke Egawa, “Job Run-time Estimation toward Energy-aware System Operation.”
