TeraGrid Phase III: eXtreme Digital Resources for Science and Engineering (XD)

In many areas of research, a key to making advances is the ability of scientists and engineers to manipulate extremely large quantities of information.  Examples include: numerical simulation and modeling; the analysis of very large datasets, whether generated by new generations of scientific instrumentation or by numerical models; and the mining of a wide range of collections of digital artifacts.   At the largest scales, the resources needed to work with huge volumes of digital information are expensive and scarce.  In recent years, the research community, with support from NSF, has developed the TeraGrid as a way of providing wide access to these scarce, expensive resources.  The need for such widely shared, national resources continues to grow and as the currently funded phase of TeraGrid operations approaches its close, NSF is inviting innovative proposals for a new infrastructure to deliver the next generation of high-end digital services, as national resources, that will provide researchers and educators with the capability to work with extremely large amounts of digitally represented information.
