JuliaQCD is a versatile tool for lattice Quantum Chromodynamics (QCD), a key framework in particle physics for studying the strong force that binds quarks and gluons. Designed for seamless scalability, it runs efficiently on CPU/GPU systems from laptops to supercomputers (e.g. Fugaku). By implementing standard algorithms like Hybrid Monte Carlo (HMC) with a focus on rapid and efficient research, JuliaQCD enables scientists to explore fundamental physics with unprecedented flexibility and speed.
JuliaQCD is a new code suite for lattice gauge theory, designed to tackle the computationally demanding problems of four-dimensional QCD and other non-Abelian gauge theories. Lattice QCD is a challenging high-performance computing (HPC) problem, requiring efficient algorithms and scalable implementations to handle large-scale simulations. JuliaQCD leverages LLVM for high-performance execution, integrates MPI for parallel computations, and utilizes Julia’s multiple dispatch for intuitive and flexible development. In addition, the latest release includes GPU acceleration through Julia’s GPU ecosystem, enabling even higher performance on modern heterogeneous HPC systems. The code suite features Hybrid Monte Carlo (HMC), support for various color and flavor extensions, lattice fermions, advanced smearing techniques, and full QCD simulations. With its focus on scalability—from laptops to supercomputers—JuliaQCD provides researchers with a powerful tool for rapid prototyping and deployment of state-of-the-art lattice gauge theory algorithms.
