Abstract

Using programmable NIC to offload network processing tasks such as checksum computation, virtual switching has become a common case in data centers. Such offloading mechanisms is able to help saving CPU cycles on servers, thus allowing data centers providing more computing resources to users for commercial benefits. However, recent research indicates that even with the offloading features above, data center servers still suffer from a great portion of CPU time being devoted to computing tasks that are unrelated to tenants. Such tasks include but not limited to data encryption and decryption, compression and decompression, etc. These tasks are common in modern data centers and cost a high amount of computational resources. Thus, in this paper, we propose a framework to offload those tasks onto programmable NIC, which will avoid high CPU usage on data center servers. On the one hand, the proposed framework is able to support multiple computing tasks running on the same programmable NIC at the same time. On the other hand, with a novel indexing mechanism, users are able to determine the order of different tasks at compile-time. Last but not least, the feasibility and advantages have been validated via our early stage experiments.
