Hello, this is Imai, a fourth-year student.
Recently, I gave a presentation at the graduation research presentation session, along with Nomura.
I was able to successfully complete the presentation and engage in meaningful discussions with both students and professors. Based on the feedback I received during the presentation, I will work even harder on writing my graduation thesis. I would like to sincerely thank all the professors and fellow students who supported me with my graduation research and presentation practice.
The final review session for the master’s thesis has been completed
Hello, this is Koda, a second-year master’s student.
Last week, I gave a presentation at the final review session for my master’s thesis. I was able to successfully complete the presentation and submit the draft version of my thesis.
I will now work on revising the final version of my thesis based on the feedback I received during the review session.
I would like to sincerely thank all the professors and fellow students who supported me with thesis revisions and presentation practice.
We held our year-end party!
Hello, this is Imai, a fourth-year undergraduate 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 2024.
In 2025, I hope to dedicate myself even more to my research.
Shubham presented at PDCAT 2024
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.
Prof.Takizawa gave talks at WSSP 38
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.
We have participated in CANDAR 2024!
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.
Takizawa Lab has participated in SC24!
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!
A imoni party was held.
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!
Prof. Takahashi presented at IEEE CLUSTER 2024
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.
A consolation party for the graduate school examination was held!
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.
