2018年4月1日から，当研究室は大学院情報科学研究科「超高速情報処理論講座」から「高性能計算論講座」に改称します．
引き続き，高性能計算システムとその応用，高性能計算システムを支えるシステムソフトウェアに関する研究に取り組んで参ります．
滝沢教授，江川准教授が第27回WSSPで研究成果を発表しました．
滝沢教授，江川准教授が3月22日，23日に当センターで開催されたWSSP(Workshop on Sustained Simulation Performance)で成果発表を行いました．
27th WSSP (https://www.sc.cc.tohoku.ac.jp/wssp27/ja/index.html)
本ワークショップは，東北大学サイバーサイエンスセンター，海洋研究開発機構(JAMSTEC)，ドイツのシュトゥットガルト大学高性能計算センター(HLRS)，およびNECが主催，JHPCNの支援を開催されました．このワークショップは国際的に活躍している計算科学の研究者及びスーパーコンピュータ設計者を招いて，高性能・高効率大規模科学計算に関する最新の研究成果の情報交換を行うとともに，今後のスーパーコンピュータの研究開発のあり方を議論をおこない，今回第27回目を迎えます． 当研究室からは滝沢教授が機械学習を用いたコード最適化，江川准教授がジョブの実行時間予測に基づくHPCシステムのための高エネルギ効率ジョブスケジューリングに関する成果を発表しました．（これらの成果は，今年度修士を取得，修了した川原畑くん，Yuqiくんの成果をまとめたものです．）

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 (https://www.sc.cc.tohoku.ac.jp/wssp27/ja/index.html)
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.)
