1. Introduction
The present investigation centers its attention in the Methods of Structured Parallel Programming, proposing a new implementation with c++ and the library of threads POSIX of the programming method based on the pattern of the High Level Parallel Compositions or CPANs from Corradi et al. [21], [22], the which it is based on the paradigm of Orientation to Objects to solve problems parallelizable using a class of concurrent active objects. In this work supply a library of classes that provides the programmer the communication/interaction patterns more commonly used in the parallel programming, in particular, the pattern of the pipeline, the pattern denominated farm and the pattern tree of the technique Divide and Conquer of design of algorithms, well-known as it.
