Abstract
In this paper, we present the design and experiments of a practical OpenMP compiler for SMP, called CCRG OpenMP Compiler, with the focus on its performance comparison with commercial Intel Fortran Compiler 8.0 using SPEC OMPM2001 benchmarks. The preliminary experiments showed that CCRG OpenMP is a quite robust and efficient compiler for most of the benchmarks except mgrid and wupwise. Then, further performance analysis of mgrid and wupwise are provided through gprof tool and Intel optimization report respectively. Based on the performance analysis, we present the optimized static schedule implementation and inter-procedural constant propagation techniques to improve the performance of CCRG OpenMP Compiler. After optimization, all of the SPEC OMPM2001 Fortran benchmarks can be executed on SMP systems efficiently as expected.
