The STEP tool allows source-to-source transformation of programs, from OpenMP to MPI, for execution on distributed-memory platforms. This paper describes tests of STEP on popular benchmarks, and analyses the results. These experiments provide both encouraging feedback and directions for improvement of the tool.
