We Participated in SWoPP 2026, xSIG 2026, and the 205th HPC Research Meeting!

Hello! I’m Tao, a Specially Appointed Assistant Professor.

From August 5 to 7, 2026, we attended SWoPP 2026 at the Hida Earth Wisdom Center in Takayama, Gifu. SWoPP, the Summer United Workshops on Parallel, Distributed and Cooperative Processing, brings together several research meetings in these fields. xSIG 2026, a cross-disciplinary workshop on computing systems, was also held on the first day.

SWoPP 2026 featured a wide range of research on high-performance computing, accelerators, programming, and scheduling. Four students from our laboratory presented their research. At xSIG 2026, Koki Watanabe presented “Semi-Automatic Host–Device Data Transfer Based on Code Analysis,” Masaki Nakatsuji presented “Evaluating the Effectiveness of Vector-Architecture Optimizations by Porting an RRI Model Implemented for the VE to GPUs,” and Yusuke Ishihara presented “A Transparent Dynamic Core Allocation Method for Hybrid MPI/OpenMP Parallel Programs.” Assistant Professor Masatoshi Kawai also chaired the xSIG-2 session. At the HPC research meeting, Makoto Ishii presented “A Scheduling Method for Disaggregated Computing Platforms That Accounts for Communication Latency and Reconfiguration.” In addition, the paper led by Yusuke Ishihara received the Best Research Award, and Koki Watanabe received the Outstanding Presentation Award. The presentations and discussions provided insights into the development and operation of high-performance computing systems, which we will apply to future research and collaborative projects.

We Introduced Our Research at the Open Campus!

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

Tohoku University recently held its annual Open Campus, and the Takizawa Laboratory also introduced our research right next to the AOBA supercomputer!
As part of our exhibition, we presented the results of a flood simulation performed using AOBA, giving visitors an example of research conducted with a supercomputer.
We also held an AI-based quiz. In the quiz, we performed AI inference using both a CPU and a GPU and visualized the computational load for each, allowing visitors to experience the differences between CPUs and GPUs.
We hope to continue our research and present interesting research results at next year’s Open Campus as well!

Selected for the Best Presentation Award at the Doctoral Student Presentation Session

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

At the Doctoral Student Presentation Session held on July 17, I presented my research entitled “代理モデルを用いたX線タイコグラフィの高速化に関する研究” and received the Best Presentation Award!

This award recognizes presentations that communicate the presenter’s research clearly and engagingly to an audience from a wide range of academic backgrounds.
X-ray ptychography may be unfamiliar to many people, so I am delighted that I was able to convey what makes this field interesting and that my presentation was recognized.

We have completed the final review of my master’s thesis!

Hi, I’m Haoran Ding, a second-year Master’s student.

Recently, Chang, Pan and I have just finished the final defense for my graduation thesis, thanks to the support of the professors and all the lab members. I could not have completed this thesis without everyone’s help.

Also, I have submitted my first draft to the Administration Office, and I will submit the polished version in the near future. I hope it turns out well!



We Participated in the 18th JHPCN Symposium!

Hi, This is Specially Appointed Assistant Professor Tao!

From July 9 to 10, 2026, we attended the 18th JHPCN Symposium at Tokyo Conference Center Shinagawa. JHPCN, the Joint Usage/Research Center for Interdisciplinary Large-scale Information Infrastructures, brings together information infrastructure centers at eight universities in Japan to promote interdisciplinary research across computational science, computer science, and data science. The symposium provided a forum for sharing the latest research results and plans from JHPCN projects.

The symposium featured a wide range of topics, including the operation of high-performance computing (HPC) systems, job scheduling and storage technologies, artificial intelligence and machine learning, weather and climate prediction, simulations in materials and life sciences, computing for disaster prevention, and quantum-HPC integration. In an invited talk titled “Quantum-Centric Supercomputing: Current Status and Future Prospects,” Hiroshi Horii of IBM Quantum Japan discussed the current state and future of next-generation computing platforms that flexibly integrate quantum processing units (QPUs), graphics processing units (GPUs), and central processing units (CPUs). From our laboratory, Prof. Takizawa presented his work on an urgent computing infrastructure that leverages supercomputers across multiple sites. The symposium reaffirmed the importance of applying advanced computing resources and system software to real-world challenges in interdisciplinary computational research. I hope to apply the insights gained to my future research and to user support at the Cyberscience Center.


We Held a Welcome Party for Our New B3 Students!

Hello! I’m Watanabe, a first-year master’s student (M1).

We recently held a welcome party for the new B3 students who have joined the Takizawa Laboratory!

Although the weather was less than ideal with light rain, we enjoyed having a barbecue together. It was also a great opportunity to get to know the new B3 members, and we all had a wonderful time.

To all of our new B3 students, welcome to the Takizawa Laboratory! We hope you’ll enjoy both your research and our laboratory activities, and we look forward to spending a fulfilling and enjoyable time together.


Talks at the 37th NEC User Group Meeting!

Hi, this is Specially Appointed Assistant Professor Tao!

From May 18 to 20, 2026, I attended the 37th NEC User Group Meeting, NUG Society Meeting XXXVII 2026, held at the Information Technology Center of the University of Cologne (ITCC) in Cologne, Germany. The NEC User Group (NUG) is an international meeting where users, operators, and developers of NEC supercomputers and high performance computing (HPC) systems share the latest technologies, operational experience, and research results.

From our laboratory, Prof. Takizawa and I gave talks. Prof. Takizawa spoke on AI-assisted programming in his talk titled “Towards AI-assisted Programming at the Tohoku University Cyberscience Center.” He introduced HPC user support activities at the Tohoku University Cyberscience Center and discussed the potential of large language models (LLMs) for code understanding, performance optimization, semantic equivalence verification, automated debugging, and performance bottleneck analysis. I gave a talk titled “A Runtime Prediction Model for Capacity Planning in Shared-Backend LLM Multi-Agent Social Simulation,” introducing AI-agent social simulation for tsunami evacuation. Based on the supercomputer AOBA and ExpressHPC, an urgent computing framework that connects multiple supercomputers, I discussed how to predict the runtime of large-scale LLM multi-agent simulations and use it for capacity planning in city-scale evacuation simulation.

The meeting also covered a wide range of topics, including NEC’s HPC and Research Information Infrastructure (HPC/RII), next-generation vector systems, RISC-V and vector extensions, GPU resource utilization, integration of HPC and AI services at RWTH Aachen University, Slurm cluster operation, storage research at the Center for Computational Sciences, University of Tsukuba, and high-performance fluid dynamics algorithms at the University of Cologne. Through this meeting, I was reminded that the future development of HPC depends on the combined progress of hardware, software, user support, and AI applications. I hope to apply the insights gained from this meeting to my future research and to user support at the Cyberscience Center.

Third-Year Undergraduate Students Have Joined Our Lab!

Hello, I am Watanabe, a first-year master’s student.

Recently, the assignment of third-year undergraduate students (B3) to research laboratories was announced, and new members have joined our lab. I am looking forward to working together with them.

With the arrival of these new junior members, I have come to realize that I am now in the position of being a senior student, which has given me a renewed sense of responsibility. Although I still have much to learn myself, I hope to support them as much as I can in both their research activities and daily life in the laboratory.

I also intend to approach my own research with even greater motivation than before and work hard to achieve meaningful results.

The global seminar has started!

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

Our Global Seminar started the other day.
With the new academic year underway, our lab activities have officially begun, and we’ve welcomed new B4 students as well as M1 students who transferred from other institutions.
With more members, the group has become even more lively, and we’ll do our best together by helping each other whenever we run into difficulties.

We went cherry blossom viewing!

Hello! I’m Imai, a second-year master’s student (M2) starting this academic year.

The other day, our lab members had a cherry blossom viewing party. The timing was perfect—the flowers were in full bloom, and the pleasant weather made it a great way to feel the arrival of spring. Personally, I especially enjoyed the pizza—it was really delicious!

I’m looking forward to working hard in the new academic year!
