ANNOUNCEMENT AND CALL FOR PARTICIPATION

WORKSHOP ON DATA REPRESENTATIONS 
IN SCIENTIFIC COMPUTING

VILLA TASSAJARA
PLEASANTON, CALIFORNIA

TUESDAY AUGUST 16, 1994

HOSTED BY
THE CLIMATE SYSTEM MODELING GROUP
LAWRENCE LIVERMORE NATIONAL LABORATORY

Dear Colleague:

Large-scale interdisciplinary computations, such as those that arise 
in climate modeling, aeronautics, and many other fields, are driving 
scientific computations to ever higher levels of complexity. This is  
especially so on parallel computers. To manage this sort of 
complexity, scientists are becoming increasingly interested in data 
abstractions. A familiar example of a data abstraction in widespread 
use can be found in the netCDF portable binary file library which 
supports an abstraction of a multi-dimensional array variable. Higher 
levels of abstraction can be found in the data models used in IBM's 
Data Explorer to visualize the many kinds of grids in current 
scientific use.

As scientific models are becoming more complex, various 
abstractions, schema, and information models are being proposed to 
deal with the increasing amount of semantic information required to 
make sense of model data. For example, such things as grid 
representations, geometry, units, and a host of parameters and 
attributes, are currently being incorporated into scientific data 
management systems and code development environments.

The purpose of this workshop is to discuss strategies for representing 
scientific data in ways that would support building tools for database 
management systems, development environments, visualization 
tools, and data archives. A number of computational scientists and 
software developers have recently presented work aimed at solving 
these problems and these efforts have begun to show an encouraging 
degree of commonality. At this workshop we would like to discuss 
these ideas and look for common features. It is hoped that the 
workshop will contribute to a community consensus on what 
scientific data looks like in most cases and how to represent it 
generically. The list of invitees includes investigators from national 
and government laboratories, industry, and academia.

This workshop is being organized by e-mail and we welcome your 
participation. Please let us know at your earliest convenience if you 
would like to participate in the workshop and especially if you would 
like to present your own work in this area. Participation is limited to 
about 60 people because of the size our facility. If you will respond 
by June 30th, we will prepare a preliminary agenda to be circulated 
by July 11th. Please reply to either of us at the addresses below. We 
look forward to hearing from you.

Sincerely,
