We present a unique and elegant graphics hardware realization of multi agent simulation. Specifically, we adapted Velocity Obstacles that suits well parallel computation on single instruction, multiple thread, SIMT, type architecture. We explore hash based nearest neighbors search to considerably optimize the algorithm when mapped on to the GPU. Moreover, to alleviate inefficiencies of agent level concurrency, primarily exposed in small agent count (<=32) scenarios, we exploit nested data parallel in unrolling the inner velocity iteration, demonstrating an appreciable performance gain. Simulation of ten thousand agents created with our system runs on current hardware at a real time rate of eighteen frames per second. Our software implementation builds on NVIDIA's CUDA.
