Event

On September 27, 2024, Assistant Professor Keichi Takahashi presented the following paper at IEEE CLUSTER 2024 held in Kobe:

Keichi Takahashi, Takashi Abe, Akihiro Musa, Yoshihiko Sato, Yoichi Shimomura, Hiroyuki Takizawa, Shunichi Koshimura, “Modernizing an Operational Real-time Tsunami Simulator to Support Diverse Hardware Platforms,” International Conference on Cluster Computing (CLUSTER 2024), Sep. 2024.

This research was funded by the Strategic Innovation Program (SIP). In this work, we ported a tsunami propagation and inundation simulation code developed for vector supercomputers to modern GPUs and CPUs and evaluated the performance of the migrated code.

The presentation slides are available on the Speaker Deck and the preprint of the paper is available on arXiv.

Hello, this is Imai from B4.
The other day, we had a party to celebrate me and Nomura’s (B4) success in passing the graduate school entrance exam over dinner.
It was a very enjoyable party where we could talk about various topics regardless of the grade.
We are going to start our research in earnest from now on, and we will do our best to keep our spirits up.

Hello, my name is Shubham, an M2 student.
I recently completed my master’s thesis final defense, focusing on the SX-Aurora TSUBASA system.
The defense was challenging but rewarding, as it allowed me to present my research findings and receive valuable feedback from the panel.
I am pleased to announce that I successfully defended my thesis and submitted it by the deadline. I am grateful to my professors and colleagues for their guidance and support throughout this journey.
I will continue to refine my work based on the comments received and look forward to contributing further to this field.

Hello, this is Tanizawa, M1 student.

SWoPP (Summer United Workshops on Parallel, Distributed and Cooperative Processing) was held at Awagin Hall (Tokushima Prefecture Local Culture Hall) in Tokushima Prefecture from 8/7-8/9. Many workshops were held, including the Workshop xSIG (Cross-disciplinary Workshop on Computing Systems, Infrastructures, and Programming) of the Information Processing Society of Japan, the HPC workshop, and the OS workshop.

From our laboratory, M1 students Katayama, Yanai, and Tanizawa presented the following papers at xSIG 2024 and the 195th HPC Workshop held at SWoPP 2024, respectively.

片山 敏伸, 高橋 慧智, 下村 陽一, 滝沢 寛之, “説明可能AI技術によるプログラムの性能モデルの解析”, xSIG 2024, 2024年8月．

柳井 快斗, 高橋 慧智, 下村 陽一, 滝沢 寛之, “タスク間の依存関係を考慮したワークフローのバッチジョブスケジューリング”, xSIG 2024, 2024年8月．

谷澤 悠太, 高橋 慧智, 下村 陽一, 滝沢 寛之, “HPCシステム用ウェブポータルにおけるジョブスケジューラの抽象化”, 研究報告ハイパフォーマンスコンピューティング (HPC), 2023-HPC-195 (9), pp. 1-9, 2024年8月.

Katayama’s presentation received the IEEE Computer Society Japan Chapter xSIG Young Researcher Award, and Yanai’s presentation received the Best Undergraduate Student Award. I would like to follow the example of my two classmates and continue to work hard in my research activities.

The other day, an open campus was held at Tohoku University, and Takizawa Lab also held a lab introduction right next to the supercomputer AOBA!
For this open campus, our students implemented a visualization of a flood simulation calculated by AOBA using Unity and showed it to the visitors!
Various people came to the event and were interested in flood simulations and various other research being conducted in Takizawa Lab!
Let’s do our best to show interesting research results at next year’s open campus!

Hello!　I am Koda, an M2 student.

The other day, we held a welcome party for three new B3 students who joined Takizawa Lab.
We had a BBQ at the welcome party, which was a great opportunity for the students to get to know each other better!

Summer vacation will soon be upon us, so let’s all do our best not to let the summer heat get the best of us!

Hello, this is Katayama, a first-year Master’s student.

From May 24th to May 31st, I attended IPDPS 2024 (the 38th IEEE International Parallel & Distributed Processing Symposium) held in San Francisco. From our laboratory, I presented at the co-located workshop iWAPT, and Choi presented at the co-located workshop JSSPP. Professor Takizawa gave a proxy presentation for Aoyagi, who graduated last year, at the co-located workshop APDCM. This paper received the Best Paper Award at APDCM. Additionally, Professor Takizawa gave proxy presentations for Ishii and Nakai, who also graduated last year, at the co-located workshop JSSPP.

Please refer to the program of the IPDPS main conference and the co-located workshops here.

Through the conference, I was able to gather information on the latest research trends in the field of high-performance computing and engage in highly beneficial discussions. I am deeply grateful to the professors and senior colleagues who have provided guidance and advice, enabling me to gain such a valuable experience. I will continue to strive in my research activities.

Hello! My name is Koda of M2

The other day, B4 students participated in the weekly local seminar held at Takizawa Lab.
In the local seminar, students report on the progress of their research and receive advice on their research from their supervisors.
B4’s research theme has been decided, and M1 and M2 will start their research activities for the conference in earnest, so let’s keep up the good work!

Hello, my name is Tanizawa, M1 student.

The Hennepata seminar, a joint effort between Takizawa Laboratory and Kobayashi/Sato Laboratory, started the other day.
The Hennepata Seminar is a seminar in which students read the book “Computer Organization and Design” written by Patterson and Hennessy and present the contents of the book.

This year, three B4 students from Takizawa Laboratory and a total of five B4 and B3 students from Kobayashi and Sato Laboratories participated as presenters. In addition, three M1 students from each laboratory are participating as advisors.

I hope to deepen my understanding of the basics of computer configuration and apply it to my future research.

Hi, this is D3 student Jin Yifan.

The 27th IEEE Symposium on Low-Power and High-Speed Chips and Systems (COOL Chips 27) was successfully held during April 17-19, 2024.

The presentations and discussions on PiM (Processing in Memory) and CiM (Compute in Memory) at the conference were impressive.
How to use these techniques to mitigate the huge amount of energy consumption generated by AI computation is becoming an important topic.

I was delighted to present the progress of my research as a poster.
I received many useful comments and suggestions from other participants.
Additionally, the discussions with other poster presenters were interesting.
