The lab explores foundational technologies for high-performance computers, such as parallel processing and networks.
AboutAbout the lab
Cutting-edge system foundation technologies for high-performance computing.
The Honda-Miwa-Yamaki Lab studies cutting-edge computer system foundation technologies for high-performance computing.
The lab's website is divided into pages for the Honda Lab, the Miwa Lab, and the Yamaki Lab.
The Miwa Lab studies topics such as power management of supercomputers and processors using next-generation semiconductors, and the Yamaki Lab studies topics such as analysis of communication content by network devices.
The Honda Lab lists computer and network architectures and software for high-performance computing as its research topics.
Key terms

ResearchResearch themes
The Miwa Lab studies power management of supercomputers, processors using next-generation semiconductors, and system software for parallel computing. The Yamaki Lab investigates what network devices that even grasp communication content can do, and explores the shape of the next-generation Internet.
*Illustrative imagePower variation in supercomputers and energy saving
Semiconductor chips such as CPUs and GPUs have variation in power consumption caused by manufacturing variation (power variation). The lab evaluates power variation in supercomputers in actual operation, and is developing resource allocation algorithms for energy saving jointly with the RIKEN Center for Computational Science.
*Illustrative imageProcessors using next-generation semiconductors
As miniaturizing silicon transistors becomes difficult, the lab is developing design techniques and architectures for processors that use carbon nanotube transistors, a next-generation semiconductor device. This research is conducted jointly with the University of Tokyo, Nagoya University, and Kyushu University.
*Illustrative imageParallel computing with multiple TEEs
The lab studies parallel computing environments that use TEEs (Trusted Execution Environments). It is developing an MPI library for fast and secure data communication between TEEs, and an encrypted file system for TEEs. This work is done jointly with the RIKEN Center for Computational Science.
*Illustrative imageNetwork applications using INT
The lab examines what can be done with networks using INT (In-band Network Telemetry), a technology in which routers attach metadata to the packets passing through them. Examples cited include specifying waypoints, proving the route a packet has taken, and estimating congestion.
