WebAug 19, 2011 · Busy wait loop is actually the default behavior under NVIDIA. Under CUDA you have an option to change the behavior into blocking synchronization or to wait on an interupt. The purpose of busy waiting is actually to get minimal latency in the responce. I don’t think that you can change the behavior with OpenCL though.
