About VerCors

VerCors is a toolset for practical mechanised verification of parallel and concurrent software under different concurrency models, notably heterogeneous and homogeneous threading. VerCors has verification support for multiple languages with concurrency features, such as Java, OpenCL (i.e. GPU kernels and atomics), and OpenMP for C (i.e. compiler directives). VerCors uses separation logic with permission accounting as its logical foundation.

The source code of VerCors is publicly available and can be downloaded from Github. Installation instructions and example verification cases are also provided. VerCors has been tested on Linux, MacOS X, and on Windows (via Cygwin). Limited documentation of the annotation language is provided at the Github Wiki.
