The actor computation model is especially suited for concurrent and distributed computations. Actors are basically concurrent processes which communicate through asynchronous message passing. When combined with pattern matching for messages, actor-based pr ...
Traditional reliable servers require costly design changes to the processor, use custom system or application software, or cannot scale beyond a few processing elements. We present TRUSS, a family of server architectures providing reliable, scalable comput ...
Dynamic Parallel Schedules (DPS) is a high-level framework for developing parallel applications on distributed memory computers (e.g. clusters of PC). Its model relies on compositional customizable split-compute-merge graphs of operations (directed acyclic ...
The aim of this thesis is the study of the simulation of electrically large structures and the application of the results to automotive Electromagnetic Compatibility (EMC). The theoretical and experimental work carried out has led to the development of com ...
Recent research indicates that prediction-based coherence optimizations offer substantial performance improvements for scientific applications in distributed shared memory multiprocessors. Important commercial applications also show sensitivity to coherenc ...
Today's Middleware is facing increasing pressures to operate in more open, loosely coupled and complex environments. E-business systems require seamless transactions between multiple enterprises and software components are becoming more opaque in an effort ...
The key principles behind current peer-to-peer research include fully distributing service functionality among all nodes participating in the system and routing individual requests based on a small amount of locally maintained state. The goals extend much ...
Distributed-memory parallel computers and networks of workstations (NOWs) both rely on efficient communication over increasingly high-speed networks. Software communication protocols are often the performance bottleneck. Several current and proposed parall ...
The remote-procedure-call abstraction, including its derivates (underlying, for example, Java RMI, CORBA, and .NET), currently represents one of the most popular paradigms for devising distributed applications. Objects (when acting as servers) are invoked ...
The purpose of this thesis is to define efficient parallel preconditioners based on the domain decomposition paradigm and to apply them to the solution of the steady compressible Euler equations. In the first part we propose and analyse various domain deco ...
