Multi-threaded Programming

Introduction

Intel Threading Building Blocks (TBB) is an open-source C++ library to support the development of mulit-threaded applications which can exploit the available processing cores in modern CPUs. Therefore, various contsructs to support parallelism in applications are provided by TBB. Low-level constructs are available to partition loops to run them distributed over many CPU cores. High-level constructs like a task scheduler and a graph-based execution model allow to express dependencies and relations between computing tasks and TBB can distribute these items among the available cores.

Furthermore, C++ classes are included that guarantee a thread-safe access to containers like lists and maps. Also explicit locking constructs like mutexes are available.

The TBB library supports the Windows, Mac OS and Linux operating systems and the Visual C++, GCC and Intel compilers.
