Historically, method-oriented middleware, such as Sun RPC, DCE, Java RMI, COM, and CORBA, has provided synchronous method invocation (SMI) models to applications. Although SMI works well for conventional client/server applications, it is not well-suited for high-performance or real-time applications due to its lack of scalability. To address this problem, the OMG has recently standardized an as...

Components can be a useful tool in software development, including the development of scientific computing applications. Many scientific applications require parallel execution, but commodity component models based on remote method invocation do not directly support the notion of parallel components. Parallel components raise questions about the semantics of method invocations and the mechanics...

In the standard kernel organization on a shared-memory multiprocessor all processors share the code and data of the operating system; explicit synchronization is used to control access to kernel data structures. Distributed-memory multicomputers use an alternative approach, in which each instance of the kernel performs local operations directly and uses remote invocation to perform remote opera...

The contribution of this work is the design, implementation and evaluation of a new aspect-oriented invocation mechanism for preserving design modularity in object code. We call our mechanism Bind. We make three basic claims. First, it is feasible to realize a programming model that supports Bind to preserve design modularity in object code. Second, the new invocation mechanism further improves...

This paper presents a generalization of the Java Remote Method Invocation model (RMI) providing an efficient group communication mechanism for parallel programming. In our Group Method Invocation model (GMI), methods can be invoked on a local object, on a remote object or on a group of objects (possibly with personalized parameters). Likewise, result values and exceptions can be returned normal...

The paper addresses the problem of reliably multicasting messages within a cluster, with an advertised latency bound that would be met with a preset confidence level. The system developed here offers, prior to an invocation, probabilistic guarantees on reliability and latency bounds and, post invocation, strives to achieve the offer chosen by the application. Pre-invocation guarantees enable de...

Implicit invocation and aspect-oriented languages provide related but distinct mechanisms for separation of concerns. Implicit invocation languages have explicitly announced events, which runs registered observer methods. Aspect-oriented languages have implicitly announced events, called “join points,” which run methodlike but more powerful advice. A limitation of implicit invocation languages ...
