ClusterMonkey points us to this news:
Version 4.2 of the GCC tool-set was just released. This release includes OpenMP which is an Application Program Interface (API) for shared-memory parallel programming in C/C++ and Fortran. OpenMP is jointly defined by a group of major computer hardware and software vendors and is a portable, scalable model that gives shared-memory parallel programmers a simple and flexible interface for developing parallel applications. While OpenMP has been around for a while, the growth of multi-core processors has made tools like OpenMP valuable to software developers.
