Employing the heterogeneous, asynchronous, PSO algorithm using 256 and 2048 particles, respectively. Each bar represents the execution time in milliseconds and each color represents a different batch size. The figure depicts that the asynchronous approach not only benefits from a fast integration method on GPU, but keeping both CPU and GPU busy with useful work is more preferable when compared to the synchronous approach. Given possible imbalance when evaluating ODEs, it is advisable to evaluate the particles in small batches
