This assignment is constructed by adapting the build scripts and PTF examples that are publicly available at p4-guide by Andy Fingerhut.

In addition, we also adapt existing scripts and tools from p4lang's P4 Tutorials which made it easy to create new exercises.

This assignment is inspired by NSDI 2021 Scaling Distributed Machine Learning with In-Network Aggregation.
