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.
