Abstract
A graphics processing unit may, in accordance with a kernel, determine that at least a first packet is written to a memory buffer of the graphics processing unit by a network interface card via a direct memory access, process the at least the first packet in accordance with the kernel, and provide a first notification to a central processing unit that the at least the first packet is processed in accordance with the kernel. The graphics processing unit may further determine that at least a second packet is written to the memory buffer by the network interface card via the direct memory access, process the at least the second packet in accordance with the kernel, where the kernel comprises a persistent kernel, and provide a second notification to the central processing unit that the at least the second packet is processed in accordance with the kernel.
