RIKEN Center for Computational Science Software Development Technology Unit

Unit Leader: Hitoshi Murai (Ph.D.)

Research Summary

Hitoshi Murai (Ph.D.)

Software Development Technology Unit works to develop outstanding infrastructure of software development that will take full advantage of the capabilities of the supercomputer Fugaku. Such infrastructure includes:

  • compilers
  • tools (performance profiler, debugger, etc.)
  • matematical libraries
  • communication libraries

In addition, we promote the use of open-source software on Fugaku to contribute to the advancement of the Arm ecosystem. We also support the evaluation and enhancement of the software developed by R-CCS.
