Research summary
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.
