Research Summary

Satoshi  Matsuoka(Ph.D.)

The High Performance Artificial Intelligence Systems Research Team is an R-CCS laboratory focusing on convergence of HPC and AI, namely high performance systems, software, and algorithms research for artificial intelligence/machine learning. In collaboration with other research institutes in HPC and AI-related research in Japan as well as globally, it seeks to develop next-generation AI technology that will utilize state-of-the-art high-performance computation facilities, including the post-K. Specifically, we conduct research on next-generation AI systems by focusing on the following topics:

  • 1.Extreme speedup and scalability of deep learning:
    Achieve extreme scalability of deep learning in large-scale supercomputing environments including the post-K, extending the latest algorithms and frameworks for deep learning.
  • 2.Performance analysis of deep learning:
    Accelerate computational kernels for AI over the state-of-the-art hardware architectures by analyzing algorithms for deep learning and other machine learning/AI, measuring their performance and constructing their performance models.
  • 3.Acceleration of modern AI algorithms:
    Accelerate advanced AI algorithms, such as ultra-deep neural networks and high-resolution GAN over images, those that require massive computational resources, using extreme-scale deep learning systems.
  • 4.Acceleration of HPC algorithms using machine learning:
    Accelerate HPC algorithms and applications using empirical models based on machine learning.
