This paper describes by example a strategy for plotting and interacting with data in multiple metric spaces. The example system was designed for use with time-varying computational fluid dynamics (CFD) datasets, but the methodology is directly applicable to other types of field data. The central objects embodied by the tool are portraits, which show the(More)
We describe a concurrent visualization pipeline designed for operation in a production supercomputing environment. The facility was initially developed on the NASA Ames "Columbia" supercomputer for a massively parallel forecast model (GEOS4). During the 2005 Atlantic hurricane season, GEOS4 was run 4 times a day under tight time constraints so that its(More)
This paper describes the hyperwall, a visualization cluster that uses coordinated visualizations for interactive exploration of multidimensional data and simulations. The system strongly leverages the human eye-brain system with a generous 7x7 array of flat panel LCD screens powered by a Beowulf cluster. With each screen backed by a workstation class PC,(More)
by in situ and remotely sensed observations have become routinely available during the past five years, and they are being applied to myriad scientific and operational problems [Stammer et al., 2002]. Under the Global Ocean Data Assimilation Experiment (GODAE), several regional and global estimates have evolved for applications in climate research, seasonal(More)
[1] It is known that General Circulation Models (GCMs) have insufficient resolution to accurately simulate hurricane near-eye structure and intensity. The increasing capabilities of high-end computers have changed this. The mesoscale-resolving finite-volume GCM (fvGCM) has been experimentally deployed on the NASA Columbia supercomputer, and its performance(More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract. Up to 1920 processors of a cluster of distributed shared memory machines at the NASA Ames Research Center are being used to simulate ocean circulation globally at horizontal resolutions of 1/4, 1/8, and 1/16-degree with the(More)
1 Basic Concept The NASA Ames " hyperwall " consists of a 7 ¡ 7 matrix of flat panel displays driven by 49 rackmounted dual-CPU nodes, each with its own high-end graphics card. It is similar to so-called " pow-erwalls " in that a cluster of computers drives a cluster of displays. However, the hyperwall's visualization utility, and hence its design(More)
