Presto

Presto is a .NET application that facilitates the easy creation of clustered applications in C# or VisualBasic

Presto provides the ability to send individual functions into a cluster of machines to be executed. Presto also provides pre built clustered data structures and a message passing system for inter-cluster communication.

Presto is currently pre-beta. While plenty of features are functional, there are still many more to implement and stress tests are still very primitive. It does not have an official release at this time.
