Abstract: The vision of this resource is that many TeraGrid users will gain material benefit from access to a set of purposely designed and supported visualization and analysis services hosted on the TeraGrid hardware operated by the UChicago/Argonne resource partner. These services will be made available via Web and Grid service interfaces in a manner that enables end users (and those supporting end users) to include them in existing applications or to use them directly via Web-based portals or other client-based tools. Our goal is to have users routinely include visualization and analysis tools as part of their production workflow. An important design consideration is that although computing centers often have large-scale and high-end visualization infrastructure, the TeraGrid end user typically does not have access to such resources. Therefore, the primary design point for services delivery needs to be aimed at the average user via a modest networking. The goal of the VDAR is to reach a larger community, reduce the barrier to entry, and to enable both users and developers by exposing applications through Web/Grid services. |
