This paper shows how the VerCors verification toolset can be used to prove data race freedom and functional correctness of a parallel radix sort algorithm for GPUs. This is a widely used standard sorting implementation for GPGPU programming frameworks and therefore its correctness is of utmost importance. Additionally, it presents the usefulness of VerCors as well as its current limitations to the scientific community.
