HOKKAIDO UNIVERSITY INFORMATION INITIATIVE CENTER

Supercomputing Research Division

We are conducting research on massively parallel computing environments driven by supercomputers and cloud systems, as well as high-performance computing utilizing state-of-the-art processor devices such as many-core microprocessors and GPUs.

More specifically, we are investigating parallel processing algorithms to enable effective use of the latest computing environments, and also developing high-performance simulation programs, modeling, and numerical computation libraries.

High-performance computing researches for supporting simulation

We conduct researches on high-performance computing for supporting various kinds of simulation on modern computer systems. Since recent supercomputers become larger and more complicated,in addition to mathematical approaches, HPC technologies such as parallelization techniques are vital for fully exploiting the potential of supercomputers. Focusing on important problems and their solution methods in the field of computational science, we have investigated related HPC technologies and developed software frameworks and libraries that support simulation. For example, we have investigate the time-space tiling techniques for iterative stencil computations and iterative methods for solving large-scale linear systems appearing in FEM-based simulation.
