// Using VkEvents, the GPU can be made to wait for the CPU and vice versa, in an effort to
// reduce this range. This function implements the following procedure:
//
// CPU GPU

//
// Post-submission work Begin execution
//
// ???? Set Event GPUReady
//
// Wait on Event GPUReady Wait on Event CPUReady

//
// Get CPU Time Te End Execution
//
