Component models are becoming more and more popular in the design of autonomic applications. In autonomic component systems, we can consider each component as an autonomic element able to dynamically reconfigure itself (maintain equilibrium with the environment by reacting to its changes). As component applications are assemblies of structured pieces of code, a powerful dynamic reconfiguration strategy...
Among derivative financial contracts, the widely traded in the financial markets are the Bermudan-American options. However, pricing high-dimensional Bermudan-American options is quite computationally intensive and using traditional computing infrastructures may take up to hours for these computations. This can result in potential financial losses, further weakening the competitiveness of an organization...
In this paper, we present a proposal for hierarchical MPI programming through some intuitive extensions to the MPI standard that may help users to develop non-embarrassingly parallel grid applications in a topology- aware manner. Afterwards, we present the design of such a support based upon a component model suited to grid computing (the EU CoreGRID grid component model - GCM - and its implementation...
This paper introduces an architecture for deploying software (components, services, etc) on distributed, large-scale computing infrastructures, like e.g. computing grids. Deployment encompasses many actions like the discovery of resources and enquiry about their current state, selection among the different versions of the software according to these states, robust, scalable and rapid software provisioning,...
We propose to address collective communications in distributed components through collective interfaces. Collective interfaces handle data distribution, parallelism and synchronization, and they expose collective behaviors in the definition of components. We show, as an illustration, that collective interfaces allow the encoding of SPMD programming in a better structured and less error prone way....
Component-based development has emerged as an effective approach to building flexible systems, but there is little experience in applying this approach to grid programming. This paper presents our experience with reengineering a high performance numerical solver to become a component-based grid application. The adopted component model is an extension of the generic fractal model that specifically...
