Event

Hello! This is Imai, a first-year master’s student.

I attended SC25, which was held in St.Louis from November 16 to 21!
SC25 is the largest international conference in the HPC industry, with 18,000 participants and over 500 organizations joining this year.

Professor Takizawa and Professor Kawai, along with students Tseng (D1), Nomura (M1), and Imai (M1), participated from our lab.
The three students presented their research posters at the Research Posters session held from November 18th to 20th.
Specifically, during the Posters Reception held on November 18th, they were able to discuss their research with researchers from all over the world.

Additionally, the students collaborated with members from other research labs at Tohoku University to set up an exhibition booth. At the booth, we introduced Tohoku University’s supercomputer systems and presented our research.

There were many lectures and exhibits that were relevant to my own research, allowing me to gain a very valuable experience.
Through the poster presentation, I received numerous ideas that I can incorporate, and I am now motivated to work even harder on my research moving forward!

Hello, I’m Tanizawa, an M2 student.

I would like to share a recent demonstration experiment conducted by the Tohoku University CyberScience Center, titled “Demonstration of Linking Multiple Heterogeneous Supercomputers for Emergency Response During Disasters”. Although I was not directly involved in the experiment, I found the results extremely interesting.

In this project, three supercomputers with different system configurations and operational setups—AOBA at Tohoku University, SQUID at Osaka University, and Furo at Nagoya University—were linked together to perform tsunami inundation predictions for three prefectures. Each calculation was completed in no more than six minutes, demonstrating the potential to rapidly utilize multiple heterogeneous supercomputers to run large-scale simulations that can contribute to disaster prevention.

This achievement represents an important first step toward building a system that can execute large-scale simulations immediately during actual disasters. Moving forward, efforts will continue to improve the technology and operational framework to establish a practical system that can be used in real-world disaster situations.

Although I was not directly involved, imagining these supercomputers working together to quickly divide and complete the calculations highlights the significant potential for applying this approach to disaster prevention.

My name is Sichen Tao, and I joined the institute on October 1st. This is my first assignment in the Tohoku region, and I am very excited to begin a new chapter of my research life in Sendai, a city rich in nature and full of energy.

My research focuses primarily on artificial intelligence (AI), including fundamental technologies such as machine learning, deep learning, reinforcement learning, brain-inspired neural networks, computational intelligence, and optimization. I am also engaged in applying these techniques to various domains such as new energy systems, high-performance computing (HPC), Industry 5.0, autonomous driving, human-machine collaboration systems, healthcare, AI for science, and automated AI algorithm design.

My hobbies include sports, singing, photography, traveling, and computer games. I value broadening my perspectives through diverse experiences and incorporating fresh ideas into my research and teaching.

I look forward to working with you all.

Hello! I’m Imai, a first-year master’s student.

We recently held an Imoni party!

It was drizzling that day, so we struggled to get the fire going, but with everyone’s cooperation, we managed to cook a delicious Imoni!
We also had a great time interacting with the new members who joined Takizawa Lab in October, making it a fun and memorable event!
It has rained for the past few years in a row, so I really hope we can have it in clear weather next year!

Hello, this is Imai, a first-year master’s student.

On October 14–15, 2025, Professor Takizawa from our laboratory gave a lecture at the 40th Workshop on Sustained Simulation Performance (WSSP40).

WSSP is a workshop jointly organized by Tohoku University’s Cyber Science Center and the High-Performance Computing Center Stuttgart (HLRS) in Germany. This time, both presenters and attendees participated in person at the Cyber Science Center, and the event saw a large turnout, making it a great success.

For details on the workshop program, please refer to this link.

Each presentation was highly insightful, and the workshop reinforced my motivation to contribute to the HPC field.

Hello, this is Tanizawa, a second-year master’s student.

The B4 members recently finished their graduate school entrance exams, so we held a small celebration to congratulate them.
Unfortunately, I couldn’t join the party due to scheduling conflicts, but I’m really glad to hear that everyone passed!
Now that the exams are over, we can finally focus on our research in earnest, and I hope we can all keep working hard together toward the graduation thesis!

Hello! This is Nakatsuji, a first-year master’s student.
Together with Professor Kawai, I attended the Japan Society for Industrial and Applied Mathematics (JSIAM), held from September 2 to 4 at the Tokyo University of Science, Kagurazaka Campus.

At JSIAM, research in a wide range of fields—from mathematics and physics to management and politics—is presented and discussed. On the second day, Professor Kawai gave a presentation titled “Evaluation of the Dynamic Load Balancing Platform (HALEOS).”

This session mainly featured HPC-related talks. I participated as an audience member, and I was able to gain a great deal of valuable information. I will do my best to make use of the insights I gained through this conference and further devote myself to my research!

Hello, this is Imai, M1 student.

SWoPP (Summer United Workshops on Parallel, Distributed and Cooperative Processing) was held at Sunport Hall Takamatsu (Takamatsu City Culture and Art Hall) in Kagawa Prefecture from 8/4-8/6. Many workshops were held, including the Workshop xSIG (Cross-disciplinary Workshop on Computing Systems, Infrastructures, and Programming) of the Information Processing Society of Japan, and the HPC workshop.

From our laboratory, M1 students Nomura, Imai presented the following papers at xSIG 2025 held at SWoPP 2025, respectively.

野村 峻也, 劉 佳恒, 高橋 慧智, 滝沢 寛之, “ RISC-Vベクトル拡張における最大ベクトル長とキャッシュ管理手法に関する検討”, xSIG 2025, 2025年8月．

今井 廉, 河合 直聡, 高橋 慧智, 滝沢 寛之, “大規模言語モデルを活用したレガシーコード近代化の実用性”, xSIG 2025, 2025年8月．

Nomura’s presentation received Outstanding Student Effort, and Imai’s presentation received Outstanding Student Award. I am deeply grateful for the invaluable support and mentorship from my professors, and I am now more determined than ever to work hard on my research.

Hello, this is Tanizawa, a second-year master’s student.

The other day, Tohoku University held its Open Campus, and the Takizawa Laboratory took part by presenting right next to the supercomputer AOBA!
This time, we showcased one of the lab’s research projects—flood simulation—on a large screen for all the visitors to see.

We’ll keep working hard so we can present even more exciting research results at next year’s Open Campus!

Hi! It’s Tseng YuTsen, an M2 student.
I just had my final defense for my graduation thesis, which was hard and full of accidents.
Still, thanks to the support of professors, other students in the lab, and many people who have supported me in the past years, it was finished successfully.
I also submitted the first version of my thesis paper and will further refine it, showing the best it can be!
