Event

I am Shubham, a first-year doctoral student.

I recently attended the PDCAT 2024 conference in Hong Kong, where I presented my research, “Leveraging Hardware Performance Counters for Predicting Workload Interference in Vector Supercomputers.” My study explores the application of machine learning to classify workloads, aiming to optimize resource management in HPC environments.
The presentation garnered insightful feedback and sparked engaging discussions with global experts. These interactions provided valuable perspectives, fostering collaboration and inspiring new approaches to tackling workload interference challenges.

Beyond the conference, Hong Kong’s vibrant culture and stunning skyline added to the memorable experience.
The city’s dynamic environment offered a perfect setting for innovation and reflection. This visit marked a significant milestone in my academic journey, reinforcing my commitment to advancing workload placement strategies in vector supercomputing and beyond.

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

On December 12–13, 2024, Professor Takizawa from our laboratory gave a lecture at the 38th Workshop on Sustained Simulation Performance (WSSP38).

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 Koda, a second-year master’s student.

I participated in CANDAR 2024, which was held in Okinawa from November 26 to 29!
From Takizawa Lab, three of us—Omura, Hang, and myself—gave presentations.

List of Presentations
・A QA-Assisted Job Scheduler for Minimizing the Impact of Urgent Computing on HPC System Operation, Tatsuyoshi Ohmura, Keichi Takahashi, Ryusuke Egawa and Hiroyuki Takizawa
・DRAS-OD: A Reinforcement Learning based Job Scheduler for On-Demand Job Scheduling in High-Performance Computing Systems, Hang Cui, Keichi Takahashi and Takahashi and Hiroyuki Takizawa
・Real-Time Phase Retrieval Using On-the-Fly Training of Sample-Specific Surrogate Models, Ryota Koda, Keichi Takahashi, Hiroyuki Takizawa, Nozomu Ishiguro and Ishiguro and Yukio Takahashi

I was initially worried about handling Q&A in English, but I was able to engage in discussions smoothly during the actual session, which was a relief. (Maybe my trip to the U.S. for SC last week helped!)
I’ll keep working hard, incorporating the feedback and advice I received.

Hello! This is Koda, a second-year master’s student.

I attended SC24, which was held in Atlanta from November 17 to 22!
SC24 is the largest international conference in the HPC industry, with 17,500 participants and over 500 organizations joining this year.

From our lab, Professor Takizawa, Shubham, and I participated in the conference.
Professor Takizawa gave a presentation titled “ExpressHPC: Towards ‘Connected Supercomputing’ Enabling On-Demand Job Execution for Disaster Resilience” at the Fourth Combined Workshop on Interactive and Urgent HPC.

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 presentations and exhibitions that were relevant to my research, making it a very valuable experience. Next year, I hope to present at a workshop, so I will continue to work hard on both my research and my English skills!

Hello! I’m Koda, a second-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!

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, I’m Imai, a fourth-year undergraduate student.
Recently, I was able to celebrate my and Nomura’s (also a fourth-year student) entrance exam success over a meal.
We had a great time talking about various topics, regardless of our year. It was a really enjoyable event.
As my research is about to begin in earnest, I am determined to stay focused and give it my all.

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!
