Classification of Different Approaches for e-Science Applications in Next Generation Computing Infrastructures

Simulation and thus scientific computing is the third pillar alongside theory and experiment in today's science and engineering. The term e-Science evolved as a new research field that focuses on collaboration in key areas of science using next generation infrastructures to extend the powers of scientific computing. This paper contributes to the field of e-Science as a study of how scientists actually work within currently existing Grid and e-Science infrastructures. Alongside numerous different scientific applications, we identified several common approaches with similar characteristics in different domains. These approaches are described together with a classification on how to perform e-Science in next generation infrastructures. The paper is thus a survey paper which provides an overview of the e-Science research domain.
