With the advent of Grid and application technologies, scientists and engineers are building
more and more complex applications to manage and process large data sets, and execute …

Find out which technologies enable the Grid and how to employ them successfully! This
invaluable text provides a complete, clear, systematic, and practical understanding of the …

Core Grid technologies are rapidly maturing, but there remains a shortage of real Grid
applications. One important reason is the lack of a simple and high-level application …

Grid technology has matured considerably over the past few years. Progress in both
implementation and standardization is reaching a level of robustness that enables …

There are many legacy code applications that cannot be run in a Grid environment without
significant modification. To avoid re-engineering of legacy code, we developed the Grid …

We investigate interoperability aspects of scientific workflow systems and argue that the
workflow execution environment, the model of computation (MoC), and the workflow …

Foundations and structure of the building blocks of GEMS, the ab initio molecular simulator
designed for implementation on the EGEE computing Grid, are analyzed. The impact of the …

Scientific workflows are an enabler of complex scientific analyses. They provide both a
portable representation and a foundation upon which results can be validated and shared …

In the business world, Service Oriented Architecture (SOA) has recently gained popularity as
a new approach to integrate business applications. In a similar way, scientific workflows can …

In this paper, we describe a Service-Oriented Architecture allowing the optimization of the
execution of service workflows. We discuss the advantages of the service-oriented approach …
