OpenMP and Automatic Parallelization in GCC

Overview This paper describes the design and implementation of the OpenMP specification v2.5 in GCC. The implementation supports all the languages specified in the standard (C, C++ and Fortran), and it is generally available on any platform that supports POSIX threads. Emphasis is placed on the internal architecture and, in particular, the intermediate representation, which could be used in the implementation of automatic parallelization techniques. The paper also presents performance results on the SPEC OMP2001 benchmark.
