Structured Dagger: A Coordination Language for Message-Driven Programming

Message-Driven Programming style avoids the use of blocking receives and allows overlap of computation and communication by scheduling processes (or objects) depending on availability of messages. Charm is a parallel programming system that uses message-driven execution to exhibit latency-tolerance. Charm supports objects whose methods can be triggered by remote objects asynchronously. Such asynchronous invocation capability endows Charm programs to tolerate communication latencies in an adaptive manner. However, many parallel object-based applications require the object to coordinate the sequencing of the execution of their methods. Structured Dagger is a coordination language built on top of Charm that supports such applications by facilitating a clear expression of the flow of control within the object without losing the performance benefits of adaptive message-driven execution.
