Soufflé: A Datalog Engine for Static Analysis

Soufflé is an open-source system for developing static program analyses in a declarative fashion. An analysis is expressed in a Datalog-like logic language. From the logic specification of the analysis, Soufflé synthesizes a highly efficient, parallel C++ program. Soufflé is currently being employed for industrial-strength static analysis problems, including large-scale program analysis and security analysis of cloud networks.

In this talk, will give an overview of the underlying technology of Soufflé, how to write Datalog-based static analyses, and present some industrial use-cases that are written in the Soufflé language. We will go beyond the scope of Soufflé as well, and discuss the performance challenges of modern Datalog engine, and possible techniques that help to solve the performance bottlenecks.
