Welcome to Threading Building Blocks.org!

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 take advantage of 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 and performance.

For developers, the clear benefits of Threading Building Blocks are:

1. TBB significantly reduces the number of lines of code required to develop multithreaded applications;
2. TBB significantly reduces the programming complexity for developing multithreaded applications (by abstracting many details of thread management);
3. TBB's task manager automatically analyzes the system the software is running on, chooses the optimal number of threads, and performs load balancing that spreads out the work evenly across all processor cores;
4. As a result, TBB threaded applications automatically scale to fully utilize all available processing cores on whatever computer they run on -- including future systems that will have many more cores than are available (or affordable) today.

If you have experience developing multithreaded C++ software (new applications, or conversion of legacy applications for operation on multi-processor/multi-core systems), you owe it to yourself to experiment with Threading Building Blocks: try recoding a few sections of software you've threaded using traditional thread libraries, and notice the difference.

The links at the right provide access to TBB resources and means for you to participate in the Threading Building Blocks community. If you have a question, feel free to post it in the TBB forums. Use the top navigation bar to access TBB's documentation and download the stable or development releases. The articles below also provide a good introduction to TBB.

Thanks for visiting ThreadingBuildingBlocks.org. We hope this is just the beginning of your interest in TBB and your engagement in the Threading Building Blocks Open Source community.
