A Networking Scenario for PetaScale Science within the DOE Office of SciencePage 1A Networking Strategy for PetaScale Science within the DOE Office of Science Over the next 510 years we expect the computation and storage capabilities within the DOE Office of Science to move to the peta scale with petaflops rates of computation using and producing multipetabytes of data. For the most demanding applications of importance to the Office of Science the pursuit of science at this peta scale will still be governed by limitations of hardware and software not by the requirements of the scientific applications. Because the highestend resources will continue to be a proverbial bottleneck efficient use of these resources will remain critical and this efficiency requirement will drive the highend needs for networking. Another requirement driving networking needs is that of secure convenient distributed collaborative access to the highend resources from a diverse group of scientists using a range of interface devices from handheld devices to desktops to synchronized distributed display walls. The efficient use of highend resources is only profitable to the extent that scientists are able to translate that use into scientific discovery. These various resource requirements in the context of trends in industrystandard information technology (IT) suggest the following networking strategy for petascale science. The highend computation and storage resources of the DOE Office of Science are tightly coupled with ultrahighbandwidth networking providing an integrated core infrastructure. Users access this core through userinterface (UI) services based on prevailing industry standards using commodity clients heavily leveraging the public and commercial IT hardware and software infrastructure. Targeting a tightly coupled integrated core maximizes the efficiency of the highend resources. Targeting commodity clients and standard IT maximizes the flexibility and accessibility of those reso ...
