Assistant Professor Keichi Takahashi presented the following paper at the 191st IPSJ SIGHPC meeting held at the Graduate School of Information Science and Technology, Tohoku University on September 26-27, 2023. This paper reports the initial performance evaluation of Cyberscience Center’s new supercomputer, AOBA-S, which started operation in August 2023.

Tohoku University Cyberscience Center had a unveiling visiting tour of new supercomputer AOBA-1.5. Prof. Takizawa explained the detail of the supercomputer, and the explanations appeared in some newspapers and TV programs.

Prof. Takizawa gave an invited talk at NEC User Group Meeting held at DWD (Deutscher Wetterdienst, the German Meteorologilal Service). The talk is to introduce our new supercomputer named AOBA-1.5, which will start operation on August 1st, 2023.

As a welcome party for B3 and a farewell party for Dominik and Sun, we had a BBQ with our lab members.
Everyone enjoyed the BBQ very much after a long absence!

Koda, M1 student in our laboratory, received the Outstanding Effort Award for his paper presented at xSIG 2023.

This award recognizes “the time and effort spent on the implementation and data acquisition related to the technical contribution of the paper”, and is an objective recognition of Koda’s efforts. We hope that this award will encourage him to aim higher!

Koda of M1 and Asia of B4 in our laboratory presented the following papers at xSIG 2023 and 190th HPC meeting held at SWoPP 2023, respectively.

After the presentation, there were many questions from the audience, indicating that there was a lot of interest in the presentation.
Let’s use this as a springboard for further development of our research!

Prof. Takahashi presented the following paper at ISC 2023, an international conference on high performance computing that was held from May 21 to 25 in Hamburg, Germany.

At an international workshop, iWAPT2023, Prof. Takizawa presented the work done by Moto Satake who completed his master course in March 2023.  The workshop is about software performance automatic tuning, so the audiences were interested in the proposed parallel execution method of Bayesian optimization, and thus we had fruitful discussions at the workshop. The information about the paper is as follows.

Hello everyone, my name is Dominik Mann. I am a M2 student in applied statistics at the University of Goettingen in Germany.
I came to the Takizawa Lab through the COLABS exchange program of the Tohoku University and will be a part of the lab for the next six months.
My main research interest involves practical applications of Machine Learning and Deep Learning. I believe that getting to know how to utilize supercomputers and high-performance computing systems in general will increase my practical skills by combining both Machine Learning and supercomputers. I am grateful for getting this opportunity in this very exciting environment and looking forward to some special experiences.
