The Distributed European Infrastructure for Supercomputing Applications is a consortium of leading national supercomputing centres that currently deploys and operates a persistent, production quality, distributed supercomputing environment with continental scope. The purpose of this EU funded research infrastructure is to enable scientific discovery across a broad spectrum of science and technology, by enhancing and reinforcing European capabilities in the area of high performance computing. This becomes possible through a deep integration of existing national high-end platforms, tightly coupled by a dedicated network and supported by innovative system and grid software.

Abstract
Aim of this chapter is to guide developers and users through the most important stages of implementing software applications on Grid infrastructures, and to discuss important challenges and potential solutions. Those challenges come from the underlying grid infrastructure, like security, resource management, and information services; the application data, data management, and the structure, volume, and location of the data; and the application architecture, monolithic or workflow, serial or parallel. As a case study, the author presents the DEISA Distributed European Infrastructure for Supercomputing Applications and describes its DEISA Extreme Computing Initiative DECI for porting and running scientific grand challenge applications. The chapter concludes with an outlook on Compute Clouds, and suggests ten rules of building a sustainable grid as a prerequisite for long-term sustainability of the grid applications.
