Multiple threads and parallel challenges for large simulations to accelerate a general Navier-Stokes CFD code on massively parallel systems

SUMMARYComputational fluid dynamics is an increasingly important application domain for computational scientists. In this paper, we propose and analyze optimizations necessary to run CFD simulations consisting of multibillion‐cell mesh models on large processor systems. Our investigation leverages t...
