Concurrent object oriented programming with Asynchronous References

In the very next future, applications will have to be highly concurrent to get some speedup from the new trend of chip-multithreading processor architecture. But writing concurrent applications is provably more difficult than developing sequential ones. We define three objectives a concurrent programming model should target to be massively adopted by the developer community. We propose such a model for imperative object oriented languages based on an extension of the standard synchronous reference called Asynchronous Reference that naturally provides the Asynchronous Method Invocation paradigm. Our model, though simple, has many interesting side effect issues such as interand intra-object concurrency degree, asynchronous policy mapping, asynchronous policy sharing, non-determinism proportion and exception handling. Our proposition can be seen as a base brick on top of which many different concurrent frameworks can be built upon. The open-source Mandala framework includes a Java implementation of our proposition.
