High Performance Computing Systems Lab
Machine-translated · View original
The lab studies the mechanisms and performance of high-performance computing, including supercomputers.
AboutAbout the lab
High-performance computing research that is useful in the real world.
The High Performance Computing Systems Lab conducts research related to high-performance computing, from massively parallel computers to clusters.
It covers computer architecture from processors to networks, system software, and high-performance numerical computing.
Using large-scale parallel computers such as Pegasus and Sirius at the Center for Computational Sciences and Miyabi at the Joint Center for Advanced High Performance Computing (JCAHPC), the lab carries out joint research with application fields of computational science.
The lab is divided into four teams: System Software, Architecture, Performance, and Algorithm.
Key terms
- GPU
- A processing unit originally built for image processing. It can perform many calculations at the same time.
- FPGA
- An integrated circuit whose circuit configuration can be rewritten after manufacturing.
- Compiler
- Software that converts a program written by a person into a form that a computer can execute.
