DEF-G is a declarative language and framework for the efficient generation of OpenCL GPU applications. Using our proof-of-concept DEF-G implementation, run-time and lines-of-code comparisons are provided for three well-known algorithms (Sobel image filtering, breadth-first search and all-pairs shortest path), each evaluated on three different platforms. The DEF-G declarative language and corresponding OpenCL kernels generated complete OpenCL applications in C/C++. Initial lines-of-code comparison demonstrates that the DEF-G applications require significantly less coding than hand-written CPU-side OpenCL applications. The run-time results demonstrate very similar performance characteristics compared to the hand-written applications. We also provide useful observations, which we found to be noteworthy for practitioners, concerning the effectiveness of certain OpenCL API options.
