Tutorial on Civl verifier for concurrent programs @ POPL 2024, January 14, 2024

by Shaz Qadeer

Constantin Enea and Shaz Qadeer will present a tutorial on the Civl verifier <https://popl24.sigplan.org/details/POPL-2024-tutorialfest/1/Scaling-Verific…> at POPL 2024 on Sunday January 14, 2024. If you are interested in automated and scalable reasoning about concurrent systems, you will find Civl of interest! A brief description of the tutorial contents is included below. ============================== Objectives: The tutorial aims to introduce the functionality of the Civl verifier, discuss its applicability and limitations, and a comparison with the state of the art. We will start with a description of practically important programming models that exhibit concurrency and require attention from verification researchers. Next, we will present an overview of trends in methods and tools for static verification of concurrent systems. Finally, we will present the different components and proof tactics implemented in Civl using illustrative examples and case studies. Topics to be covered: The tutorial will be structured in several sections that address the objectives mentioned above. 1. Classes of concurrent systems whose construction deserve reasoning support: - concurrent tasks operating on shared-memory (locks, non-blocking algorithms, weak memory, GPU programs) - processes communicating via channels, RPCs (distributed systems) - hardware controllers (memory controllers, pipelined processors), mixed hardware-software controllers (embedded systems) 2. Overview of trends in static concurrency reasoning: - Powering up program logics: extensions of Floyd-Hoare such as Owicki-Gries, Rely-Guarantee, Concurrent Separation Logic, etc. - The approach in Civl: amplifying simple program logics via orthogonal methods such as commutativity, linear types, refinement - Proof discovery: heuristic automation of proofs atop a particular proof system (much like the automation of type inference atop type checking) 3. Programming model of Civl: structured programs with possibly parallel and asynchronous procedure calls 4. Verification in Civl: - Yield invariants: noninterference reasoning that is as precise as Owicki-Gries and as compositional as rely-guarantee - Mover types: reduce interference using verification conditions for checking commutativity of atomic actions and a type system based on Lipton’s reduction - Ownership: disjoint distribution of resources ensured via linear types and verification conditions 5. Layered refinement in Civl: - Lifting refinement over transition systems to refinement over structured programs - A refinement chain of structured programs expressed as a single layered program - Each link in the refinement chain justified by a simulation proof supported by verification methods noted in #4 Presentation approach: The presentation will be driven by examples to illustrate challenges, explanation of core methods accessible to non-experts, and tool demonstration. Target audience: Researchers interested in concurrent systems, program analysis, and program verification Prerequisite knowledge: Logic, invariants, verification conditions, program analysis

IARCS Verification Seminar Series -- Talk by Madhusudan Parthasarathy on Nov. 28 at 1900 hrs IST

by VSS IARCS

Dear all, The next talk in the IARCS Verification Seminar Series will be given by Madhusudan Parthasarathy, a Professor of Computer Science at the University of Illinois at Urbana-Champaign. The talk is scheduled on Tuesday, Nov. 28, at 1900 hrs IST (add to Google calendar <https://calendar.google.com/calendar/event?action=TEMPLATE&tmeid=MzViZ3N0an…> ). The details of the talk can be found on our webpage ( https://fmindia.cmi.ac.in/vss/), and also appended to the body of this email. The Verification Seminar Series, an initiative by the Indian Association for Research in Computing Science (IARCS), is a monthly, online talk-series, broadly in the area of Formal Methods and Programming Languages, with applications in Verification and Synthesis. The aim of this talk-series is to provide a platform for Formal Methods researchers to interact regularly. In addition, we hope that it will make it easier for researchers to explore newer problems/areas and collaborate on them, and for younger researchers to start working in these areas. All are welcome to join. Best regards, Akash, Deepak, Madhukar, Srivathsan ============================================================= Title: Learning Logical Expressions Meeting Link: https://us02web.zoom.us/j/89164094870?pwd=eUFNRWp0bHYxRVpwVVNoVUdHU0djQT09 (Meeting ID: 891 6409 4870, Passcode: 082194) Abstract: We consider the problem of learning logical formulas/expressions that work as classifiers of structures. Logic learning has many applications ranging from program synthesis from input-output examples, learning specifications from code (contracts and inductive invariants), interpretable concept learning in AI, synthesizing lemmas to help prove theorems, finding axiomatizations, and, more generally, replacing certain creative tasks that currently require human help in many applications. We will first motivate logic learning using the applications above. We then will turn a theory lens to this problem by considering when the logic learning problem is *decidable*. We show a general technique using tree automata that realize learning algorithms for a variety of logics/languages ranging from fragments of FOL, regular expressions, temporal logics, grammars, to string transformation for Excel (as in Flashfill). We in fact will show a *meta-theorem* that can be used to show a logic is decidable simply by programming a particular kind of evaluator for its semantics. This theory suggests that many logics can be learned by using Version Space Algebras (VSAs) based on tree automata. If time permits, we will also consider the problem of learning logics themselves to aid few-shot learning. Bio: Madhusudan Parthasarathy is a Professor of Computer Science at the University of Illinois at Urbana-Champaign. He has worked on several projects that turn the theory lens to problems in software verification including visibly pushdown languages, ICE-learning for learning inductive invariants, and natural proofs for proving programs that manipulate data structures. His current interests are in software verification, program synthesis, and trustworthy AI.
