AboutAbout the lab
Creating future supercomputers and pioneering the technologies to put them to use.
The Takizawa-Kawai Lab conducts research aimed at creating next-generation supercomputing technologies.
Research proceeds while examining the supercomputers actually in operation at the Cyberscience Center and the challenges they face.
The core of the lab's work is system software technologies that bring out the performance of supercomputers, and the exploration of new ways to use them.
The lab also works on automating the tasks of expert programmers with machine learning, and on operation linked with observational data.
Key terms
- High-performance computing
- A technical field concerned with performing large volumes of scientific and engineering computation quickly using large-scale computers
- System software
- Software that sits between applications and the computer, supporting the allocation of computing resources and the execution of programs
- Vector processor
- A processor for scientific and engineering computation that excels at performing the same operation on many data at once

ResearchResearch themes
Keeping in mind the supercomputers in actual operation at Tohoku University's Cyberscience Center and the challenges they face, the lab aims to create next-generation supercomputing technologies. Its focus is system software technologies that make maximum use of performance, and the exploration of new ways to use supercomputers.
*Illustrative imageCyber-Physical Systems and Supercomputers
Sensors and IoT devices generate vast amounts of data moment by moment. Aiming for supercomputers that can be operated flexibly in tandem with such real-time observational data, the lab develops system software that allows computers normally used for academic research to also be used for disaster prevention and mitigation in emergencies.
*Illustrative imageMachine Learning for Software Development Support
Programming, performance analysis, and debugging are highly intellectual tasks, and it may be difficult to leave all of them to machine learning, but it may be able to take over part of the work that people have done. The lab studies how to use machine learning effectively in software development.
*Illustrative imageAn Environment for Using Diverse Processors Appropriately
Specialized processors can execute particular kinds of processing more efficiently than general-purpose processors, and recent supercomputers are equipped with multiple types of processors. The lab studies programming environments for using vector processors, GPUs, quantum annealers, reconfigurable devices, and others where each is best suited.
*Illustrative imageMastering Supercomputers and Pushing Their Limits
Supercomputers will become larger and more complex in the future. Mastering them is itself a research challenge, and the lab studies high-performance computing broadly, from system design to usage techniques, and leads an international joint research project that supports performance optimization.
