I am a Postdoctoral Researcher at the Center for Computational Sciences (CCS), University of Tsukuba, Japan. My research focuses on Lattice Field Theory, aiming to understand the strong force, one of the fundamental interactions in nature. To achieve such research goals, I develop numerical tools that leverage HPC across diverse architectures, including both CPUs and GPUs. Recently, I have also been interested in applying Machine Learning to accelerate lattice calculations.

Lattice QCD simulations are restricted by both massive computational costs and high memory requirements. To simulate large physical volumes, distributing the lattice across multiple GPUs is essential. We present JuliaQCD, a native Julia ecosystem designed for computations on HPCs. By integrating JACC.jl for vendor-neutral GPU kernels and MPI.jl for lattice decomposition, we enable simulations on lattices that exceed the memory capacity of a single device while maintaining high performance.
