Event

Hello, this is Tanizawa, an M2 student.
The final master’s thesis defense was held recently. In Takizawa Laboratory, Katayama, Yanai, and I each gave our presentations. I’m happy to say that we all finished successfully and were able to submit the duplicate copies of our theses by the deadline.
Using the helpful feedback we received from the examiners, I’ll keep refining my thesis as we work toward submitting the final official version.
I’d like to give a big thank you to the professors and everyone in the lab — both seniors and juniors — for supporting us with revisions and presentation practice. I really appreciate all your help!

Hello.
My name is Yuta Tanizawa, an M2 student.

I participated in HPCAsia 2026, which was held from January 26 to 29, 2026, at the Osaka International Convention Center (Grand Cube Osaka).

This conference was jointly organized by SupercomputingAsia (SCA) and The International Conference on High Performance Computing in Asia-Pacific Region (HPC Asia), and is one of the major international conferences and events in the field of high-performance computing (HPC).
SCA was launched in 2018 and has been jointly organized every year by HPC centers in Australia, Japan, Singapore, and Thailand. HPC Asia, on the other hand, is a long-standing international conference on HPC technologies in the Asia–Pacific region, with a history dating back to the 1990s.

From our laboratory, Tseng, Pan, Katayama, and Tanizawa participated in the conference and gave the following presentations:

“TRIOS: Reducing File-System Contention through Predictive Time-Resolved I/O Simulation in Job Scheduling”
YuTsen Tseng, Masatoshi Kawai, Keichi Takahashi, Hiroyuki Takizawa

“CityScaleCast: Spatiotemporal GNN for City-Scale Weather Prediction with GraphCast-Guided Parallel Modeling and Multi-Step Forecasting in Sendai”
Xuanwen Pan (Tohoku University)

“Explainable AI-Guided Genetic Algorithms for Efficient Software Automatic Tuning”
Toshinobu Katayama (Tohoku University)

“Semantic Equivalence Verification of HPC Codes Using LLMs”
Yuta Tanizawa (Tohoku University)

In addition, Professor Hiroyuki Takizawa gave the following presentation:

“Cyberscience Center”
Hiroyuki Takizawa (Tohoku University)

Furthermore, during the poster session, we also presented posters showcasing research from Tohoku University. Many attendees stopped by our booth, and through explanations and discussions about our research and systems, we were able to receive valuable feedback from researchers and industry professionals from both Japan and abroad.

Throughout the conference, numerous talks and presentations were delivered on the latest research and technological trends in the HPC field, making it an extremely stimulating experience. Through our presentations and exhibitions, we had an excellent opportunity to reexamine our research from various perspectives.
By leveraging the knowledge and ideas gained through our participation in HPCAsia 2026, I would like to further advance my research and continue to engage in research activities with renewed motivation.

Hello! I’m Koda, a D1 student.

At the ongoing SCA/HPCAsia 2026 conference, the award ceremony for the 2025 APAC HPC/AI Competition was held. Team To(Hoku)^2_w/R, consisting of Koda and Shubham from the Takizawa Lab and Yuya Kudo from Hokkaido University, received the “Certificate of Participation and Excellence”!
Our team tackled the HPC task of accelerating NWChem. We worked on the acceleration from July to September and presented the acceleration results in October.

At the awards ceremony, we discussed the specifics of the acceleration with students from the winning team. While our approach was similar, we didn’t place among the top winners, but we achieved a satisfying result!

Hello! This is Imai, a first-year master’s student.
The year-end party was held recently.
It was a great event where we could have open conversations regardless of nationality or academic year, making it a wonderful way to wrap up 2025.
In 2026, I hope to dedicate myself even more to my research!
