Intel Threading BuildingBlocks（Intel TBB）介绍

Intel Threading BuildingBlocks（Intel TBB）是一个使用ISO C++代码实现的多平台、可扩展并行编程库。下边首先给出一个免费版本的TBB下载链接：打开链接

(1)what's  Intel Threading BuildingBlocks（Intel TBB）？

         The Intel® Threading Building Blocks (Intel® TBB) library provides software developers with a solution for enabling parallelism in C++ applications and libraries. The well-known advantage of the Intel TBB library is that it makes parallel performance and scalability easily accessible to software developers writing loop- and task-based applications. The library includes a number of generic parallel algorithms, concurrent containers, support for dependency and data flow graphs, thread local storage, a work-stealing task scheduler for task based programming, synchronization primitives, a scalable memory allocator and more. 

(2)TBB的结构：

上图的内容可以分为以下几类：

• 通用并行算法  TBB提供了parallel_for，parallel_while，parallel_reduce等算法，应用于不同的并行算法场景
• 并发容器   这是对常见容器的线程安全版本的实现，同时考虑到性能要求，提供了细粒度的锁机制，TBB2.0里提供的容器包括hash map，vector，queue。
• 任务调度器：提供了task机制的封装
• 同步原语：提供了原子操作、mutex、lock等同步原语的封装
• 内存分配：提供了对cache机制更友好的支持
