Non-determinism in MPI applications negatively impacts the debugging and correctness of high performance computing (HPC) and scientific simulations. To help developers and scientists study and understand sources of non-determinism, we present ANACIN-X, a software framework for quantifying point-to-point communication non-determinism in MPI applications as graph kernel distances. ANACIN-X includes three benchmark applications for testing (i.e., message race, algebraic multigrid, and unstructured mesh).
