SUMMARY:P4 Developer Days - Enabling Portable and High-Performance SmartNIC Programs with Alkali
DESCRIPTION:Date: October 1\, 2025\nTime: 9:00am Pacific \nVIEW VIDEO \nVIEW SLIDES \nAbstract\nProgramming SmartNICs today is notoriously difficult. NICs from different vendors—or even different generations of the same vendor—exhibit significant variation in hardware parallelism\, memory hierarchies\, and interconnects. As a result\, porting programs across NICs is labor-intensive and requires extensive manual refactoring to meet performance expectations on each target. \nIn this presentation\, we will present the demo and design of Alkali\, a SmartNIC compilation framework that enables developers to write target-independent programs\, while the compiler automatically handles cross-NIC porting and performance tuning. Alkali achieves this by: (1) introducing a novel intermediate representation (IR) that supports building a reusable and extensible compiler across diverse NICs\, and (2) developing an optimization algorithm that automatically transforms and parallelizes programs based on the target NIC’s hardware characteristics. \nAlkali is built on the MLIR infrastructure and is fully open source (https://github.com/utnslab/Alkali). It currently supports four distinct NIC backends and continues to grow\, including future support for P4 as part of an effort to make SmartNIC programming more portable and productive. \nSpeakers\nJiaxin Lin is an incoming assistant professor at Cornell University. She received her Ph.D. from UT Austin in the summer of 2025. Her research aims to design innovative software and hardware for accelerated data center networks. She has received the Google and Meta PhD Fellowships in Computer Networking and was selected as an MIT EECS Rising Star in 2024. \n  \n \nZhiyuan Guo is a final-year PhD student at UC San Diego. His research focuses on co-designing datacenter systems and applications for resource disaggregation. He is actively extending the concept of disaggregation and cohesive design to various datacenter systems\, including remote memory\, networking accelerators\, and machine learning infrastructure. \n  \n
