Parallel Patterns Library


The Parallel Patterns Library is a Microsoft library designed for use by native C++ developers that provides features for multicore programming. It was first bundled with Visual Studio 2010. It resembles the C++ Standard Library in style and works well with the C++11 language feature, lambdas, also introduced with Visual Studio 2010.
For example, this sequential loop:
for

Can be made into a parallel loop by replacing the for with a parallel_for:
#include
//...
Concurrency::parallel_for ;
This still requires the developer to know that the loop is parallelizable, but all the other work is done by the library.
MSDN describes the Parallel Patterns Library as an "imperative programming model that promotes scalability and ease-of-use for developing concurrent applications." It uses the Concurrency Runtime for scheduling and resource management and provides generic, type-safe algorithms and containers for use in parallel applications.
