Transcript DAME Overview/Introduction - Department of Computer Science

The DAME project
Professor Jim Austin
University of York
Origins
• Funded by EPSRC under the governments eScience
initiative.
• Total government funds in eScience exceeds £220M
• Started as a result of existing work at the
collaborators sites
• Built on the WRG metropolitan Grid
• Few of us were Grid experts at the start!

Project Partners
• EPSRC Funded, £3.2 Million, 3 years, commenced
Jan 2002.
• UK pilot project for e-Science
• Aims to show the utility of Grid computing for data
and compute intensive engineering problems
• A generic system applicable in many domains

DAME Grid Challenges
• Building a demonstration system as proof of concept
for Grid technology in the aerospace diagnostic
domain.
• Two primary Grid challenges:
– Management of large, distributed and heterogeneous data
repositories;
– Rapid data mining and analysis of fault data;
• Other key (commercial) issues:
– Remote, secure access to flight data and other operational
data and resources;
– Management of distributed users and resources;
– Quality of Service issues (and Service Level Agreements)

The Data
• Each flight could produce up to 1GB of vibration data
• This is archived in distributed data repositories (EDS)

Demonstrator Objectives
The DAME demonstration system provides a
diagnosis workbench (portal) which brings together a
suite of analysis services via Grid technology;
– Provides access to a range of analysis tools for the engine
diagnosis process
– Will act as central control point for automated workflows
– Manages issues of distributed diagnosis team and virtual
organisations
– Manages issues of security and user roles.
