The lab studies next-generation computers that connect diverse machines and run them intelligently.
AboutAbout the lab
Connecting computers and running them intelligently.
The Sakamoto Lab studies methods for connecting and intelligently operating a wide range of computers, from supercomputers and the cloud to embedded devices.
It designs hardware such as accelerators and networks together with software such as operating systems and cloud platforms.
Considering everything from compilers to algorithms as a whole, the lab aims for computing systems that are high-performance, highly reliable, and low in power consumption.
Key terms
- accelerator
- A dedicated device for performing a specific computation quickly. It takes over processing from the CPU
- microservices
- A development approach in which one application is built as small services that are then connected together
- domain-specific architecture
- Hardware built specifically for applications in a particular field. It is fast and requires less power
ResearchResearch themes
The lab researches building computing systems that are high-performance, highly reliable, and low-power through coordination and cooperation across diverse system layers. Its designs span circuit implementation, architecture, compilers, system software, and algorithms.
*Illustrative imageNext-generation supercomputers
In supercomputer development, power consumption constrains performance and design. The lab studies scheduling and resource management that make effective use of computing resources and power resources, aiming for systems that run batch processing and streaming processing efficiently.
*Illustrative imageMicroservice execution platforms
Microservices are easy to develop, but container management and communication become a burden and lower execution efficiency. The lab aims for a platform that tightly connects services using next-generation non-volatile memory and FPGAs, delivering high execution performance while preserving abstraction.
*Illustrative imageDomain-specific architectures
Computing on hardware specialized for a particular application is fast and also keeps power consumption low. The lab studies architectures such as AI accelerators, shortest-path computation accelerators, and network processing accelerators.
