With .NET 4, Parallel LINQ (PLINQ) enables you to scale up an application that uses LINQ to Objects, and easily leverage all of the CPU power of a single machine. At the same time, Map Reduce has shown to be successful in solving classes of large-scale data problems. This session will demonstrate how the power of PLINQ can distribute a computation, not just across multiple cores in the same machine, but over multiple machines and very large data sets.
