How well do Grid systems satisfy end-user requirements?

The GRIDWELTEN project aimed to evaluate and make recommendations regarding the use of high performance computing resources accessible through Grid software and architectures. The metric for this comparison was the expectations and requirements of the end user situated at the sites of the project partners and at other HPC-centres throughout Germany.

The final project documentation is presented in three main sections: firstly, a summary of user requirements for Grid computing, secondly, an evaluation of selected Grid computing environments, and thirdly a detailed analysis. Typical user groups come from many areas of science, and we were careful to assimulate the expectations of each into a set of common requirements. With this in mind, a survey of the end users was conducted.

The findings of other relevant research in the area of Grid usability is also discussed. Selected Grid middleware and supporting software are reviewed. In particular, we matched and compared the end user expectations and the features of some popular Grid infrastructures. For this we considered four Grid systems: GLOBUS, UNICORE, TME and InnerGrid.

In the report we also examine the implications of the Open Grid Services Architecture (OGSA) proposed by the Global Grid Forum, on the operation and future interopability of the evaluated systems.
