He made a presentation on “Performance evaluation of inter-process communication of SX-Aurora TSUBASA”.

2018/07/27 Presentation at SX-Aurora TSUBASA Forum

I gave a talk at SX-Aurora TSUBASA Forum taken place at the NEC headquarter.
My talk was about a hot topic, the performance and functionality of NEC’s new product, SX-Aurora TSUBASA.
I am glad the audiences enjoyed it.

2018/05/26 Presentation at iWAPT2018

I attended IPDPS 2018 in Vancouver, and gave a talk at the international workshop on automatic performance tuning, iWAPT 2018, on behalf of Yuki Kawarabatake who was the first author of the work. During the stay, I also visited Stanley Park, a great park full of nature. It’s a pity I am not good at taking a selfie… 🙁

2018/05/18 NUG30＠Aachen

I have presented our joint research effort at NUG30@Aachen Germany. I stayed as a visiting researcher at RWTH GRS in Aachen from Aug. to Oct. 2011, but it was my first visit in about seven years. The townscape was unchanged from that time, and I felt relieved somehow :-).

My talk at NUG 30

Aachen (nothing has changed 🙂 )

Lab member of Prof. Roller’s Group (Aug. 2011)

2018/04/04 Laboratory name is changed to “High-Performance Computing”

From April 1, 2018, our laboratory will be renamed “Ultra High Speed Information Processing” to “High Performance Computing”.

We will continue to work on research on high performance computing systems and their applications, and also system software that supports high performance computing systems.

2018/03/23 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.)

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

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

2018/03/10 Professor Takizawa and Associate Professor Egawa presented at SIAM 2018.

In SIAM 2018 held at Waseda University on March 9th and 10th, we proposed the following mini-symposium plan together with TACC of USA and HLRS of Germany and made presentations respectively.
