Abstract
A single CPU core is not fast enough to process packets arriving from the network on commodity NICs. Applications are therefore turning to application-level partitioning and NIC offload to exploit parallelism on multicore systems and relieve the CPU. Although NIC offload techniques are not new, programmable NICs have emerged as a way for custom packet processing offload. However, it is not clear what parts of the application should be offloaded to a programmable NIC for improving parallelism.
We propose an approach that combines application-level partitioning and packet steering with a programmable NIC. Applications partition data in DRAM between CPU cores, and steer requests to the correct core by parsing L7 packet headers on a programmable NIC. This approach improves request-level parallelism but keeps the partitioning scheme transparent to clients. We believe this approach can reduce latency and improve throughput because it utilizes multicore systems efficiently, and applications can improve partitioning scheme without impacting clients.
