Parallel computing is a form of computation in which many operations are carried out simultaneously. In the “age of many-core”, developers are getting more and more interesting in using easily all the “power” of the CPU.
Visual Studio 2010, the .NET Framework 4, and Visual C++ 2010 all contain new support for writing, debugging, and tuning parallel applications.
Learn more about Parallel computing on Microsoft MSDN Site.
