As of this writing, the following operations in MFIX have been offloaded: - -- Neighbor particles / neighbor list construction -- Particle-particle collisions -- Particle-wall collisions -- PIC Deposition (used in putting the drag force and solids volume fraction on the grid) +MFiX-Exa currently runs on both CPU-only and hybrid CPU/GPU architectures. -- GitLab
