The Uniform Interface to Computing Resources offers a ready-to-run Grid system including client and server software. UNICORE makes distributed computing and data resources available in a seamless and secure way in intranets and the internet. The UNICORE project created software that allows users to submit jobs to remote high performance computing resources without having to learn details of the target operating system, data storage conventions and techniques, or administrative policies and procedures at the target site.

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.
