Distributed Objects for Parallel Numerical Applications

Abstract

Abstract. The C++// language (pronounced C++ parallel) was designed and implemented with the aim of importing reusability into parallel and concurrent programming, in the framework of a mimd model. From a reduced set of rather simple primitives, comprehensive and versatile libraries are defined. In the absence of any syntactical extension, the C++// user writes standard C++ code. The libraries are themselves extensible by the final users, making C++// an open system. Two specific techniques to improve performances of a distributed object language such as C++// are then presented: Sharedon-Read and Overlapping of Communication and Computation. The appliance of those techniques is guided by the programmer at a very high-level of abstraction, so the additional work to yield those good performance improvements is kept to the minimum.Mathematics Subject Classification. 68N15, 68N19.

Middleware reliability implementations and connector wrappers

“…In addition to highlighting additional connector wrappers, formalization afforded insight into how to implement an interesting semantic model of active-object concurrency, called wait-by-necessity [4]. In this model, active objects asynchronously invoke the methods of other active objects and continue processing while these methods execute.…”
