| The map above shows current traffic flows and traffic patterns across GLORIAD - as measured in Chicago. In the map, triangles show source of traffic; inverted trianges, destination. Sites connected by arcs are the heavist current consumers. Colors indicate network protocols and can be discovered by the listing of top users at the right. The small charts show traffic volume by application during the last two hours. Clicking on any of them takes you to a larger display. | ||
Project: AeroDB Trials
Description: The objective of this work, led by scientists at NASA Ames Research Lab, is to build a prototype software system to automate the process of running computational fluid dynamics (CFD) jobs on Grid resources. This objective was motivated by scientists and aerospace engineers at NASA who are working on advanced aerospace designs and who require large numbers of parametric simulations to evaluate designs prior to physical construction and testing. AeroDB is a set of scripts that execute and monitor simulation test cases for a given design problem. AeroDB was designed to take advantage of the uniformity offered by current Grid infrastructures, enabling it to easily use authorized resources from any Globus Toolkit-based Grid. In its initial trial, AeroDB scripts were used to execute and monitor cases for a large parameter study on a Liquid Glide-back Booster (LGBB) vehicle. This trial, conducted in 2002, used computing elements provided by NASA's Information Power Grid (IPG), NSF's NPACI Grid, and NSF's Alliance Grid. Within 72 hours, more than 1,000 Cart3D and 100 Overflow cases had completed, having run on 13 distinct systems at NASA Ames, NASA Glenn, NCSA, and USC ISI.
