We review the efforts of the Open Grid Computing Environments collaboration. By adopting a general three-tiered architecture based on common standards for portlets and Grid Web Services, we can deliver numerous capabilities to science gateways from our diverse constituent efforts. In this paper, we discuss our support for standards-based Grid portlets using(More)
During the initial stages of copper electrodeposition onto a thin seed layer, a nonuniform potential distribution arises, resulting in local variations in growth rate and deposit morphology. Early stages of morphology evolution during copper electrodeposition are of practical importance but have not been well studied. Here, a new multiscale approach is(More)
ach year across the US, mesoscale weather events—flash floods, tornadoes, hail, strong winds, lightning, and localized winter storms—cause hundreds of deaths, routinely disrupt transportation and commerce , and lead to economic losses averaging more than US$13 billion. 1 Although mitigating the impacts of such events would yield enormous economic and(More)
The design and prototype implementation of the XCAT Grid Science Portal is described in this paper. The portal lets grid application programmers easily script complex distributed computations and package these applications with simple interfaces for others to use. Each application is packaged as a "notebook" which consists of web pages and editable(More)
—This paper describes an approach to building Grid applications based on the premise that users who wish to access and run these applications prefer to do so without becoming experts on Grid technology. We describe an application architecture based on wrapping user applications and application workflows as web services and web service resources. These(More)
GGF DOCUMENT SUBMISSION CHECKLIST (include as front page of submission)The GGF document format to be used for both GWD's and GFD's is available in MSWord, RTF, and PDF formats. (note that font type is not part of the requirement, however authors should avoid font sizes smaller than 10pt). Status of This Memo This memo provides information to the Grid(More)
Within a decade after John von Neumann and colleagues conducted the first experimental weather forecast on the ENIAC computer in the late 1940s, numerical models of the atmosphere became the foundation of modern day weather forecasting and one of the driving application areas in computer science. This article describes research that is enabling a major(More)
Copper electrodeposition in submicron trenches involves phenomena that span many orders of magnitude in time and length scales. In the present work, two codes that simulate electrochemical phenomena on different time and length scales were externally linked. A Monte Carlo code simulated surface phenomena in order to resolve surface roughness evolution and(More)
