The 17th Workshop
on Sustained Simulation

- Toward Future HPC Technologies -

The purpose of this workshop is to report Japan’s research activities for post petasclae high-end computing, and also to discuss emerging applications and technologies in the next decade. In 2012, Japan started a two-year program to investigate feasibility on development of post K computer. Four research teams have been involved in this program. Three teams, headed by Tohoku U., U. of Tsukuba, and U. of Tokyo, have been working with NEC, Hitachi, and Fujitsu to study on three types of next supercomputers. A team headed by AICS is responsible for studying scientific and social issues to be solved by 2020 and making a science road map until 2020.

The workshop consists of talks from 4 teams and invited talks that covers topics from innovative devices to system architectures, and to science and engineering applications in the post-petascale era.
