The purpose of the DEISA Extreme Computing Initiative (DECI) is to enhance the impact of the DEISA research infrastructure on leading European science and technology. DECI identifies, enables, deploys and operates “flagship” applications in selected areas of science and technology. These leading, ground breaking applications must deal with complex, demanding, innovative simulations that would not be possible without the DEISA infrastructure, and which would benefit from the exceptional resources of the Consortium.

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.
