littlefoo writes "Intel Software Dispatch have announced the availability of the Threading Building Blocks (TBB) template library under the GPL v2 with the run-time exception — so this previously commercial only package is now open for all the use, whether for open-source projects or commercial offerings (although they are explicitly encouraging open source use). The interface is more task-based then thread-based, but with a somewhat different view of things than, e.g. OpenMP. From the Intel release: 'Intel® Threading Building Blocks (TBB) offers a rich and complete approach to expressing parallelism in a C++ program. It is a library that helps you leverage multi-core processor performance without having to be a threading expert. Threading Building Blocks is not just a threads-replacement library. It represents a higher-level, task-based parallelism that abstracts platform details and threading mechanism for performance and scalability.'"
