In his presentation to the International Summer School on Grid Computing 2008 in Hungary last week titled "e-Science with UNICORE," Morris Riedel of the Juelich Supercomputing Center in Germany focused on how the UNICORE middleware is used with scientific applications. While doing so, he also illustrated more generally the relationships between science and e-science, and between e-science and grids. Riedel presented the concept that the natural sciences nowadays have three pillars: alongside theory and experiment stands computational techniques. Further, the infrastructures enabling e-science may be viewed as a fourth pillar. He quoted a definition by John Taylor which reads: "e-Science is about global collaboration in key areas of science and the next generation infrastructure that will enable it." And what are these next generation infrastructures? Today grids provide the enabling infrastructure for data-intensive, compute-intensive, collaborative, international science. The image illustrates the components of an e-science application destined for execution on a grid. It also illustrates the role of middleware in a grid, the layer of software between the applications and a distributed, often hetergeneous computational architecture.
