Verification of MPI programs using CIVL

CIVL is a framework for verifying concurrent programs. The framework is built around a language, CIVL-C, that extends sequential C with general-purpose primitives that can be used to model a variety of concurrency dialects, including OpenMP, Pthreads, CUDA, and MPI. The framework automatically transforms programs using those dialects into CIVL-C so that static analysis and verification tools for CIVL-C can be applied. This paper describes how C/MPI programs are so transformed. The result is a verifier that can check, within finite bounds, a number of difficult properties of MPI programs, including functional correctness, deadlock-freedom, and adherence to rules specified in the MPI Standard.
