Dapper, or “Distributed and Parallel Program
Execution Runtime”, is a tool for taming the
complexities of developing for large-scale cloud
and grid computing, enabling the user to create
distributed computations from the essentials: the
code that will execute, along with a dataflow
graph description. It supports rich execution
semantics, carefree deployment, a robust control
protocol, modification of the dataflow graph at
runtime, and an intuitive user interface.

Changes:
A new, flexible logging infrastructure has been added. Initializers for logging structures have been moved out of the Server and Client classes and into drivers. Finite state machines have been updated to the new annotation-driven API. The source code has been normalized to have 8 spaces instead of tabs.
