Cascade:
a collaboration between Cray Inc, JPL/Caltech, Notre Dame,
and Stanford, aimed at developing a commercially available system
capable of sustained performance in excess of one petaflops (a
million billion calculations per second. This work is funded by
DARPA's HPCS program, formed to sponsor development of the next
generation of high productivity computing systems - systems which
are more broadly applicable, much easier to program, and more
resistant to failure than currently available high performance
computing systems. The JPL/Caltech part of this project builds on
the successful work on the Gilgamesh project.

Common Component Architecture:
a demonstration of the CCA Forum
technologies applied to applications being developed in the ESTO CT Project.
The objective of the CCA Forum is to define a minimal set of standard interfaces that a high-performance component framework has to provide to components, and can expect from them, in order to allow disparate components to be composed together to build a running application. Such a standard will promote interoperability between components developed by different teams across different institutions.

Digital Light Table (DLT):
a visualization tool designed to interactively explore terabyte-scale terrain
(image and elevation) data sets on multi-screen power walls or desktop displays.

Earth and Space Science Applications on the Information Power
Grid (IPG):
Tuning 3 separate applications to the IPG and executing in a Grid environment:
National Virtual Observatory, creating an all-sky set of 'science-grade'
virtual plates in the optical and IR at 1 arc-sec;
SRTM Data Analysis, developing continental-scale stream network maps using the
SRTM DEM (topo) data; and Ocean Modeling, establishing an angoing IPG
capability for ocean simulation using high-resolution coastal modeling with
tri-level 3D ocean models, with ultimate focus on detailed modeling of the
West Coast carbon exchange process. For information on this task,
contact Dave Curkendall.

EOS Data Visualization Using Self-Organizing Map:
A visualization system for multispectral and multivariant EOS datasets.
Sponsored by JPL's R&TD fund in 2003, the PAT group teamed up with a
MISR scientist and developed a
prototype interactive visualization and analysis system for 36-channel
MISR images. The team applied the Self-Organizing Map (SOM) algorithm and
Voronoi diagram to reduce a multi-dimensional EOS dataset into a small set of
colors. The system is able to extract features visible in only a few
channels and identify subtle differences among channels.
For more information see: the project web page.

Gilgamesh:
The Gilgamesh prototype board, conceived and developed by Caltech and
JPL, provides a hardware testbed critical in evaluation of efficiency
and functionality of various Processor-In-Memory (PIM) implementation
concepts. The board, based on Field Programmable Gate Array (FPGA)
technology, allows unlimited reconfigurability and rapid prototyping in
which new or modified logic structures can be quickly instantiated and
tested with no more than an order of magnitude penalty with the respect
to the projected target clock frequency.
For more information on the PAT group's work on this project,
contact Gary Block.

Global Earth Mosaic:
A seamless, global, half-arc-second resolution Earth Landsat 7 mosaic.
Combining about 8000 individual Landsat 7 scenes (each 500 Megabytes in size)
into a seamless, browsable mosaic. The mosaic will
be provided on the web using the OpenGIS WMS protocol, providing a
rich source of background imagery for many other applications. A further
refinement of the MapUS project, the server will
provide on-demand
spectral band combinations, various projection systems, and basic image
control such as brightness, gamma correction and sharpening. The web
server address is
http://OnEarth.jpl.nasa.gov/.

|
Grist:
a grid-technology based system and prototype research
environment for data mining with massive and complex astronomical
datasets. When complete, this knowledge extraction system will consist
of a library of distributed grid services controlled by a workflow
system, compliant with standards emerging from the grid computing, web
services, and virtual observatory communities. The Grist services will
include data access, federation, mining, source extraction, image
mosaicking, catalog federation, data subsetting, statistics, and
visualization. For more information:
http://grist.caltech.edu/.

MapUS:
an internet front end to a one arc-second LandSAT map of the US.
LandSAT images have been mosaicked to form one large seamless image of
the continental US, and the WMS protocol allows you to interactively
explore the resulting image. You can select which of the six LandSAT
bands you map to the red, green and blue components of the image.
Selected geopolitical information from the National Atlas can be drawn
on top of the image, and a three arc-second elevation map can be used
to add shadow effects.
The MapUS server is at http://MapUS.jpl.nasa.gov/.

Montage:
a production-level, data-agile, Grid-aware, and science-quality
astronomical image mosaicking and serving component of the National
Virtual Observatory (NVO). Montage is being designed and developed
under "High Performance Cornerstone Technologies for the NVO", a Round 3
Grand Challenge project, sponsored by NASA Earth Science Technology
Office (ESTO), Computational Technologies (CT) Project.
The Montage home page is at http://montage.ipac.caltech.edu/.

Multi-Surface Light Table (MSLT):
a portable tool to display earthquake faults as translucent underground
surfaces with the associated 3D terrain. This tool is based on the
DLT. It is funded by ESTO CT and is being developed for use
by the
QuakeSim project
(one of the ESTO-CT Round III application teams.)

OurOcean:
a web-based end-to-end system for data retrieval, archiving, processing, and
distribution with a focus on the East Pacific Ocean wind.

SAR:
The SAR Imaging and Interferometric Science Applications Project was
one of the 2nd Round Grand Challenge Projects sponsored by the
NASA High Performance Computing and Communication (HPCC) Program, Earth and
Space Science (ESS) Project (now known as the
ESTO Computational Technologies
Project.) It was a three-year project from 1996 - 1999, managed by
Dave Curkendall.
The project achieved performance milestones of 10, 50, and 100 gigaflops, and
designed and implemented the Scalable SAR Software Suite (S4), a
publicly available set of software for high performance SAR image and
interferometry processing (InSAR).
