We introduce an object-oriented framework for parallel programming, which is based on the observation that programming objects can be naturally interpreted as processes. A parallel program consists of a collection of persistent processes that communicate by executing remote methods. We discuss code parallelization and process persistence, and explain the main ideas in the context of computation...

Six generations of RPC systems can be distinguished including Federated Method Invocation presented in this paper. Some of them—CORBA, Java RMI, and Web/OGSA services—support distributed objects. However, creating object wrappers implementing remote interfaces doesn’t have a great deal to do with object-oriented distributed programming. Distributed objects developed that way are usually ill-str...

Classes are fundamental elements in object-oriented programming, but they cannot be assembled in a truly flexible manner from other classes. As a result, cross-cutting structural code for implementing associations, graph structures, and so forth must be implemented over and over again. Subobject-oriented programming overcomes this problem by augmenting object-oriented programming with subobject...

Context Parallel computing is an important field within the sciences. With the emergence of multi, and soon many, core CPUs this is moving more and more into the domain of general computing. HPC programmers want performance, but at the moment this comes at a cost; parallel languages are either efficient or conceptually simple, but not both. Aim To develop and evaluate a novel programming paradi...

Ideally, being a programmer means I can do anything on a computer. I have complete freedom, complete control. But in reality, programmers today have very It is time to begin the next technology revolution in software development, and the shape of this revolution is becoming more and more clear. The next programming paradigm is nearly upon us. It is not yet fully formed—different parts have diff...

Multiple dispatching and the visitor pattern are approaches to making object-oriented programs more extensible. Both have a flavor of pattern matching, thereby moving objectoriented programming closer to functional programming. The key idea of these approaches can be crystallized as a notion of visitor which lies between functions and objects. Can this idea be developed into a new form of visit...

The promise of agent-based systems is leading towards the development of autonomous, heterogeneous agents, designed by a variety of research/industrial groups and distributed over a variety of platforms and environments. Teamwork among these heterogeneous agents is critical in realizing the full potential of these systems and scaling up to the demands of large-scale applications. Unfortunately,...

This dissertation describes the design and implementation of a general-purpose object-oriented (OO) programming language, Classages. The novel object model of Classages gives programmers refined control over modeling the interactions inside OO software, with inspirations drawn from human sociology. Key innovations include the language constructs of Mixers and Connectors as encapsulation-enforce...

Context-dependent behavior is becoming increasingly important for a wide range of application domains, from pervasive computing to common business applications. Unfortunately, mainstream programming languages do not provide mechanisms that enable software entities to adapt their behavior dynamically to the current execution context. This leads developers to adopt convoluted designs to achieve t...

We introduce MathOptInterface, an abstract data structure for representing mathematical optimization problems based on combining predefined functions and sets. MathOptInterface is significantly more general than existing structures in the literature, encompassing, example, a spectrum of classes from integer programming with indicator constraints to bilinear semidefinite programming. also outlin...
