Abstract:

Explore how a less efficient, but highly parallel algorithm can still be a superior alternative to a sequential CPU method. This talk will present a simple CUDA-based Poisson solver to the conjugate gradient method designed for solving well-conditioned matrices such as those that arise from the pressure projection stage of a Navier-Stokes fluid solver. In contrast to other active areas of research in this field, we show that a more brute force approach can still significantly out-perform the best CPU alternatives by sacrificing a high convergence rate in place of achieving much faster iterations.
