    A performance portable fast Ewald summation for Stokes flow

    Gabriel Kosmacher, Ziyu Du, Joar Bagge, George Biros

    math.NA · cs.DC · physics.comp-ph

    We present GPU algorithms for Ewald summation methods for accelerating N-body Stokes flow problems in periodic domains. Like most N-body codes, Ewald sums use a near-field/far-field decomposition. The near field involves particle-to-particle (P2P) interactions. The far field primarily involves particle-to-grid (P2G) and grid-to-particle (G2P) interactions, as well as Fast Fourier Transforms. For each interaction, we investigate several...
