Research Summary

Our unit conducts a series of research and development activities, including the development, support, and performance evaluation of HPC applications, as well as benchmarks, with a focus on co-design for next-generation HPC infrastructure namely Fugaku NEXT. We also aim to create fundamental technologies that accelerate and enhance the functionality of HPC applications by integrating simulation and advanced AI technologies. To effectively and efficiently promote these activities, we will develop and release various frameworks.
