Distributed systems are notoriously hard to get right. Programming these systems is challenging because of the need to reason about the myriad possible interleaving of messages and failures. Unsurprisingly, it is common to uncover bugs after deployment.

Formal methods (FM) can play an important role in addressing this challenge. But the key requirement for “success” in is the ability to integrate FM in all the phases of development process from system design, implementation, to unit and integration testing, and even in production through runtime monitoring.

In this talk, we will provide an overview of the P programming framework. P is a state machine-based programming language for modeling and specifying complex distributed systems. We will discuss how P is currently being used extensively inside Industry and Academia, addressing the challenges mentioned above. P is open-source: https://p-org.github.io/P/
