TBB Tutorial
This document gives a quick example of how to use Intel's Thread Building Blocks, by means of a simple example. The example is available as a tarball here . The files are also available as syntax-highlighted HTML here ( fatals.* and hrtime.h are elided).

Until now, the example programs of previous sections provided very little interaction with the user, if any at all. Using the standard input and output library, we will be able to interact with the user by printing messages on the screen and getting the user's input from the keyboard.

Abstract Class vs Interface
Introduction : There are lost of discussion on the internet about the Interface vs Abstract class. Also, as base class whether we have to use interface, abstract class or normal class.
C++ Interface Classes - An Introduction
Class hierarchies that have run-time polymorphism as one of their prominent characteristics are a common design feature in C++ programs, and with good design, it should not be necessary for users of a class to be concerned with its implementation details. One of the mechanisms for achieving this objective is the separation of a class's interface from its implementation.
Featured Algorithm: Intel Threading Building Blocks: parallel_reduce
In our first two installments of the Featured Algorithm series, we looked at parallel_for and pipeline , popular ways to start using Intel Threading Building Blocks to gain performance increases on multi-core platforms. Next, we focus on the parallel_reduce algorithm. In his book, (O'Reilly, 2007), James Reinders describes a reduction operation as the process of applying a function such as , , , or logical across all the members of a group. Unlike a parallel_for, the parallel_reduce operation has a splitting constructor and a join method (for merging the results).
