Short summary of current research:
Photonic technologies are emerging as a promising solution to meet the growing demand for faster and more energy-efficient AI computations. To fully realize the potential of photonic computing, it is crucial to identify additional applications for this technology. One promising application is lattice Quantum Chromodynamics (QCD) calculations. Lattice QCD, which consumes a significant portion of public supercomputer resources, requires substantial computational power, with 50-99 of the time spent solving discrete partial differential equations, typically in the form of linear systems Ax b. This heavy reliance on matrix-vector multiplications presents an opportunity to offload these operations to photonic accelerators. Moreover, the use of mixed precision methods to accelerate calculations on GPUs—by leveraging lower-precision arithmetic—has already been extensively studied. These methods could be adapted to utilize the fast, energy-efficient, albeit less accurate, photonic matrix-vector multiplications, while still achieving the necessary double precision. Therefore, exploring the application of photonic technologies for lattice QCD calculations represents an exciting and innovative direction for photonic computing platforms.
