Concurrency and Coordination Runtime
Concurrency and Coordination Runtime (CCR) is an asynchronous programming library based on .NET Framework from Microsoft distributed with Microsoft Robotics Developer Studio (MRDS). Even though it comes with MRDS, it is not limited to modelling robotic behavior but can be used to express asynchronous behavior in any application.
CCR runtime includes a Dispatcher
class that implements a Thread pool, with a fixed number of threads, all of which can execute simultaneously. Each dispatcher includes a queue (called DispatcherQueue
) of delegates, which represent the entry point to a procedure (called work item) that can be executed asynchronously. The work items are then distributed across the threads for execution. A dispatcher object also contains a generic Port
which is a queue where the result of the asynchronous execution of a work item is put. Each work item can be associated with a ReceiverTask
object which consumes the result for further processing. An Arbiter
manages the ReceiverTask
and invokes them when the result they are expecting is ready and put on the Port
queue.
In May 2010, the CCR was made available along with the entire Robotics Developer Studio in one package, for free. Microsoft Robotics Developer Studio 2008 R3. [1]
