Hello! This is Watanabe, a fourth-year undergraduate student.

We recently had our undergraduate thesis presentation, and Ishihara and I (both B4 students) gave our presentations. We were able to complete them successfully and had meaningful discussions with both students and professors.

Based on the valuable comments we received during the presentation, we will continue working hard on writing our undergraduate thesis and our xSIG paper.
We would like to sincerely thank all the professors and students who supported us with our research and presentation practice.

Hello! I’m Koda, a first-year doctoral student.

The other day, we held a farewell party for M2 students Katayama, Tanizawa, and Yanai, who are graduating this year!
Since it was hard to coordinate everyone’s schedules, we split the farewell party into two sessions, but both were fun and lively!
We wish the M2 students entering the workforce all the best in their future endeavors!

Hello, this is Imai, an M1 student.

On February 17th, the Multidisciplinary Seminar took place, followed by the Techno Festival on February 18th and 19th.
During the Multidisciplinary Seminar, I presented my research findings and future plans to representatives from private companies and other M1 students from different research labs. Additionally, in the Matchmaking Session held within the Techno Festival, I attended company presentations from various businesses to gain a deeper understanding of their work.

Explaining my research in simple terms that non-experts could understand was quite challenging, but it was a great learning experience. Furthermore, listening to other students’ research and the company presentations broadened my perspective, making the event highly valuable.

I will continue to work hard on my research, taking into account the feedback I received!

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.
