This page contains Isabelle theory files for proving correctness of hybrid transactional memory in a modular fashion, leveraging the TMS2 specification and Lesani et al's results, these proofs establish opacity of two novel hybrid versions of the Dalessandro et al.'s transactional mutex lock .

Modularisation is based on a concept we refer to as open I/O automata.

Download the theory files here. The zip file consists of two folders:

  • naive, a simple implementation and proof, where the fast and slow path both synchronise on the same global variable, and
  • 2-Counter, an improved implementation and proof, where the slow- and fast-path transactions synchronise on different variables, allowing more concurrency.

The proofs require Isabelle 2016.

If you encounter a problem loading Seq.thy, please make sure imports is set to "../HOLCF". This is a problem with the new Isabelle distribution.
