EXPLICIT MOVING PARTICLE SIMULATION METHOD ON GPU CLUSTERS

EXPLICIT MOVING PARTICLE SIMULATION METHOD ON GPU CLUSTERS

Taniguchi, D.; Sato, L. M.; Cheng, L. Y.

Full Article:

Moving Particle Semi-implicit (MPS) is a Lagrangian, meshfree, computational method for fluid simulation. This work focus on using GPU clusters for MPS simulations. To accomplish this, we have to deal with two different levels of parallelism: one responsible for making different cluster nodes work together in a distributed memory system, and the other using the parallelism of GPU devices available on each node. First we present a performance comparison between single-node GPU and single-node multithreaded CPU implementations to investigate GPU speedups. Further, we analyze the performance in a multi-node GPU cluster environment.
