DescriptionEnsuring correctness in HPC applications is one of the fundamental challenges that the HPC community faces today. While significant advances in verification, testing, and debugging have been made to isolate software defects in the context of non-HPC software, several factors make achieving correctness in HPC applications and systems much more challenging than in general systems software---growing heterogeneity (CPUs, GPUs, and special purpose accelerators), massive scale computations, use of combined parallel programing models (e.g., MPI+X), new scalable numerical algorithms (e.g., to leverage reduced precision in floating-point arithmetic), and aggressive compiler optimizations/transformations are some of the challenges that make correctness harder in HPC. As the complexity of future architectures, algorithms, and applications increases, the ability to fully exploit exascale systems will be limited without correctness. The goal of the workshop is to bring together researchers and developers to present and discuss novel ideas to address the problem of correctness in HPC.
