GPU Accelerated Dissipative Particle Dynamics with Parallel Cell-list Updating

A general purpose DPD simulation entirely implemented on GPU is presented in this paper, including cell-list updating, force calculation and integrating forward. The algorithm and optimization needed to obtain best performance of GPU is discussed. The performance benchmarks show that our implementation running on single GPU can be more than 20x faster than conventional implementation running on single CPU core and 10x faster than that running on 5 CPU cores.
