Abstract
Over the past 35 years, the speed of fluid flow simulations reflected the increase in transistor densities as predicted by Moore's law. Recent improvements in compute capability, however, highlight a slowing trend: difficulties in extracting fine-grain parallelism, the divergence between flops and memory bandwidth, and the additional burden on solver developers who are now expected to manage complex memory hierarchies explicitly are all contributing factors. Yet the speed demands on fluid simulations for applications that require multiple evaluations including design exploration and optimization, uncertainty quantification, AI/ML, reduced-order modeling, digital twins, etc., are continuing to increase. In this dissertation we focus on the study of a possible alternative to bridge the gap between the predicted shortcomings in Moore's law and the requirements of many of these applications. We discuss the possibility of developing application-specific integrated circuits (ASIC) to solve the equations of fluid flow using a Lattice-Boltzmann Method (LBM) approach. We begin with a brief discussion of the LBM approach, focused on computation and communication requirements, and compare the relative performance and merits of implementations on GPUs, FPGAs, and ASIC. Preliminary conclusions indicate that performance improvements of 74x, relative to a state-of-the-art GPU, may be possible using and ASIC with feature sizes of 7 nm or smaller
