Abstract/Summary In reacting flow simulations, considerable computational effort is spent on updating the change of composition due to chemical reactions. As a means of accelerating the simulation of reacting flows, we have been investigating the use of graphics processing units (GPUs) to compute the chemistry update in a massively parallel manner. We have some evidence from previous work that our use of the GPU is less than optimal because of imbalances in the workload that is sent to the GPU. In the present work, we implement several new strategies to better order the workload of chemistry updates that are processed by the GPU and test the performance of these strategies. The results show that we can achieve a speed-up of 1.4x for a particular flow case with hydrogen/ oygen combustion when using a GPU accelerator. The results also show that the performance of the GPU accelerator is insensitive to the workload odering.
