SUMMARY:Protocol Buffer Deserialization DPU Offloading in the RPC Datapath
DESCRIPTION:Raphaël Frantz (Eindhoven University of Technology, Netherland
 s); Jerónimo Sánchez García (Aalborg University, Copenhagen); Marcin Copik
  (ETH Zürich); Idelfonso Tafur Monroy (Eindhoven University of Technology,
  Netherlands); and Juan José Vegas Olmos, Gil Bloch, and Salvatore Di Giro
 lamo (NVIDIA Corporation)\n\nIn the microservice paradigm, monolithic appl
 ications are decomposed into finer-grained modules invoked independently i
 n a data-flow fashion. The different modules communicate through remote pr
 ocedure calls (RPCs), which constitute a critical component of the infrast
 ructure. To ensure portable passage of RPC metadata, arguments, and return
  values between different microservices, RPCs involve serialization/deseri
 alization activities, part of the RPC data center tax. We demonstrate how 
 RPC server logic, including serialization/deserialization, can be offloade
 d to Data Processing Units (DPUs). This effectively reduces the RPC data c
 enter tax on the host, where applications' business logic runs. While we f
 ocus on offloading Protocol Buffers deserialization used by the popular gR
 PC framework, our findings can be applied to other RPC infrastructures. Ou
 r experimental results demonstrate that RPC offloading performs similarly 
 to traditional methods while significantly reducing CPU usage.\n\nTag: I/O
