Does .net 4.0 Task Parallel Library replace MPI.NET for High-performace computings?
MPI.NET found here http://www.osl.iu.edu/research/mpi.net/svn/ is a high-performance, easy-to-use implementation of the Message Passing Interface (MPI) for Microsoft's .NET environment. MPI is the de facto standard for writing parallel programs running on a distributed memory system, such as a compute cluster.
.NET 4 TPL says: "The Task Parallel Library (TPL) is a set of public types and APIs in the System.Threading and System.Threading.Tasks namespaces in the .NET Framework version 4. The purpose of the TPL is to make developers more productive by simplifying the process of adding parallelism and concurrency to applications. The TPL scales the degree of concurrency dynamically to most efficiently use all the processors that are available. In addition, the TPL handles the partitioning of the work, the scheduling of threads on the ThreadPool, cancellation support, state management, and other low-level details. By using TPL, you can maximize the performance of your code while focusing on the work that your program is designed to accomplish."
My Target is to build an application that can run on Windows HPC 2008 ... which way to go?

The Task Parallel Library (TPL) is a set of public types and APIs in the System. Threading and System. Threading. Tasks namespaces. The purpose of the TPL is to make developers more productive by simplifying the process of adding parallelism and concurrency to applications.
Compared to the classic threading model in . NET, Task Parallel Library minimizes the complexity of using threads and provides an abstraction through a set of APIs that help developers focus more on the application program instead of focusing on how the threads will be provisioned.
The Task Parallel Library (TPL) is based on the concept of a task, which represents an asynchronous operation. In some ways, a task resembles a thread or ThreadPool work item but at a higher level of abstraction. The term task parallelism refers to one or more independent tasks running concurrently.
From what I understand TPL does not support distributed computing while MPI.NET does.
