High-Performance Computing Lab
Machine-translated · View original
A lab that researches the technologies needed to build next-generation supercomputers and make full use of them.
AboutAbout the lab
Creating the supercomputers of the future and pioneering the technologies to use them.
The High-Performance Computing Lab aims to create next-generation supercomputing technologies. It researches areas such as fundamental software technologies that make the most of supercomputer performance.
Recently, the lab has been working on using machine learning to automate programming work that skilled programmers have traditionally done by hand as a craft. It is also researching how to use supercomputers flexibly in coordination with real-time observation data.
The lab also studies how to use vector processors, quantum computers, and hardware that can be reconfigured to suit each application effectively in supercomputing.
On the lab's website, it is introduced under the name Takizawa Lab.
Key terms
- Supercomputer
- A large and complex computing system. It has become indispensable for numerical simulation in science and technology
- Vector processor
- A processor that is good at performing the same operation on large amounts of data at once. It is one type of processor installed in recent supercomputers
- Cyber-physical system
- A system that links real-world data collected by sensors and other devices with processing on computers
- Performance optimization
- The work of modifying programs so that they can bring out the full performance of a supercomputer

ResearchResearch themes
The lab aims to create next-generation supercomputing technologies, with an eye on the supercomputers actually operated at the Cyberscience Center of Tohoku University and the challenges they face. Its research focuses on fundamental software technologies that make the most of supercomputer performance and on pioneering new ways to use supercomputers.
*Illustrative imageA supercomputing platform that can also be used in emergencies
The lab works toward cyber-physical systems, aiming for supercomputers that can be operated flexibly in coordination with observation data produced by sensors and IoT devices. It develops fundamental software technologies so that supercomputers normally used for academic research can also be used quickly and reliably in emergencies, such as for disaster prevention and mitigation.
*Illustrative imageMachine learning for software development support
The lab is exploring whether machine learning can replace some of the work people have done in software development, such as programming, performance analysis, and debugging. It studies how to use machine learning effectively in software development.
*Illustrative imageAn environment for using diverse processors
Recent supercomputers are increasingly equipped with several types of processors that have different strengths and weaknesses. The lab researches how to use vector processors, GPUs, quantum annealers, reconfigurable devices, and others, each where it fits best.
*Illustrative imageMastering supercomputers and pushing their limits
The lab researches and develops high-performance computing technologies broadly, from system design to the programming and usage techniques needed to make full use of the systems. In supporting performance optimization to bring out the best in supercomputers, it leads a large-scale international collaborative research project.
