NCSA's goal is to create a balanced system that fully supports high-end computing as well as: 1) high-end data management and
analysis; 2) visualization of massive, highly complex data collections; 3) large databases; 4) geographically distributed
Grid computing; and 5) collaboratories, all based on a secure computational environment and driven with workflow-based
services. To this end NCSA has defined a new technology path that includes the integration and provision of cyberservices in
support of data analysis, mining, and visualization.
NCSA has begun to develop and apply a data mining system-NCSA Data-to-Knowledge (D2K)-in conjunction with both the
application and research communities. NCSA D2K will enable the formation of model-based application workflows and visual
programming interfaces for rapid data analysis. The Java-based D2K framework, which integrates analytical data mining methods
with data management, data transformation, and information visualization tools, will be configurable from the cyberservices
(web and grid services, tools, ..) viewpoint to solve a wide range of important data mining problems. This effort will use
modules, such as a new classification methods for the detection of high-risk geoscience events, and existing D2K data
management, machine learning, and information visualization modules. A D2K cyberservices interface will be developed to
seamlessly connect client applications with remote back-end D2K servers, providing computational resources for data mining
and integration with local or remote data stores. This work is being coordinated with SDSC's data and services efforts.
The new NCSA Visualization embedded workflow environment (NVIEW) will be integrated with D2K functionality to tightly couple
informatics and scientific visualization with the data analysis and management services. Visualization services will access
and filter disparate data sources, simplifying tasks such as fusing related data from distinct sources into a coherent visual
representation. This approach enables collaboration among geographically dispersed researchers via portals and front-end
clients, and the coupling with data management services enables recording associations among datasets and building annotation
systems into visualization tools and portals, giving scientists a persistent, shareable, virtual lab notebook.
To facilitate provision of these cyberservices to the national community, NCSA will be providing a computational environment
for large-scale data assimilation, analysis, mining, and visualization. This will be initially implemented on the new 512
processor shared memory SGI's recently purchased by NCSA. In addition to standard batch capabilities, NCSA will provide
on-demand capabilities for those projects requiring rapid response (e.g., development of severe weather, earthquake events)
for decision makers. It will also be used for non-sequential interactive analysis of data sets where it is important have
access to large data volumes over space and time.
