Abstract: Execution of a first kernel may be offloaded from a central processing unit to a graphics processing unit using a ring task buffer with a fixed number of task slots incurring full overhead of runtime driver interaction. Execution of a second kernel is offloaded using said ring task buffer, so at least two kernels may be offloaded from a central processing unit to a graphics processing unit via said ring task buffer, while incurring about the same offloading overhead as would be incurred from offloading a single kernel, in some embodiments. Multiple kernels are automatically grouped together by a compiler and linker.
