This paper presents a program logic for reasoning about multithreaded Java-like programs
with dynamic thread creation, thread joining and reentrant object monitors. The logic is …

We describe the design and implementation of methods to support reasoning about data
races in GPU kernels where constructs other than the standard barrier primitive are used for …

We report on practical experiences over the last 2.5 years related to the engineering of
GPUVerify, a static verification tool for OpenCL and CUDA GPU kernels, plotting the …

Prefix sums are key building blocks in the implementation of many concurrent software
applications, and recently much work has gone into efficiently implementing prefix sums to …

This paper presents the VerCors approach to verification of concurrent software. It first
discusses why verification of concurrent software is important, but also challenging. Then it …

Data-dependent GPU kernels, whose data or control flow are dependent on the input of the
program, are difficult to verify because they require reasoning about shared state …

Abstract We study a Hoare Logic to reason about GPU kernels, which are parallel programs
executed on GPUs. We consider the SIMT (Single Instruction Multiple Threads) execution …

GPUVerify is a static analysis tool for verifying that GPU kernels are free from data races and
barrier divergence. It is intended as an automatic tool, but its usability is impaired by the fact …

I present a tutorial overview demonstrating the key technique used by GPUVerify, a static
verification tool for graphics processing unit (GPU) kernels. The technique is a method for …

Todays business and scientific applications have a high computing demand due to the
increasing data size and the demand for responsiveness. Many such applications have a …
