Abstract
A heterogeneous computing system includes a central processing unit (CPU) and a graphics processing unit (GPU). The CPU and the GPU are synchronized using a data-based synchronization scheme, wherein offloading of a kernel from the CPU to the GPU is coordinated based upon the data associated with the kernel transferred between the CPU and the GPU. By using a data-based synchronization scheme, additional synchronization operations between the CPU and the GPU are reduced or eliminated, and the overhead of offloading a process from the CPU to the GPU is reduced.
