Full HTML Index
Successful conference held in 1997 and 1998 in Dayton with 1998 objectives of:
Provide an overview of multidisciplinary design and analysis environments.
Initiate interaction between multidisciplinary tool developers and users.
Stimulate thinking about potential multidisciplinary applications.
Explore advanced computing systems where multidisciplinary applications are likely to be executed.
Sessions on Integrated Frameworks and the building blocks for them; distributed and collaborative visualization; applications
  • included special workshop on MDICE -- a particular CFD framework
Organizing committee chair in 1998 was Dr. Ruth Pachter ASC

Full HTML Index
In 1999, PET leadership of MAPINT will be Dr. Richard Luczak and Geoffrey Fox
Basic Parameters as before : (end) Summer 1999 Dayton
Similar objectives but maturing of ideas allows some focussed sessions -- these are very preliminary suggestions
  • Tutorial on Gateway and using/building Problem Solving Environments
  • Session on same topic but emphasizing people outside our Gateway project
  • Session on emerging advanced algorithms
  • Strong applications session
  • Session on National Machine Room and PC Clusters
Help Please!

Foil 5 Java Grande Activity DATORR Desktop Access to Remote Resources

From Review of MAPINT and Gateway at ASC ARL ASC Joint Mid Year Review Aberdeen Maryland -- Feb 23-25 1999. *
Full HTML Index
Development of ASC Gateway coincides with DATORR standardization initiative
DATORR Could lead to definition of CORBA facilities or Java framework for computing services
DATORR Defines:
  • Abstract Task Specification ("user view")
  • Metacomputing Services API ("system view")
  • This includes definitions of properties of a computer/database/network and establishing Security Standards

Foil 6 Motivation for Datorr Why desktop access?

From Review of MAPINT and Gateway at ASC ARL ASC Joint Mid Year Review Aberdeen Maryland -- Feb 23-25 1999. *
Full HTML Index
Very many machines, platforms, Operating Systems
Though a good/necessary thing, using them in changing environment becomes difficult for users.
Goal:
  • Enable Uniform or seamless access to general backend compute, communication and information resources
  • Hide details and satisfy "majority of" customers
Datorr will help metacomputing but goals are focussed on a subset of issues and aimed at establishing interoperability standards -- reference implementations may follow but are not direct goal

Provides infrastructure supporting development of problem solving environments (PSE)
  • create user space
  • define problem
  • identify resources
Provides seamless and secure access to remote resources
  • allocate resources
  • monitor resources
Initial PSE is CCM and this will provide template for others -- early on CEA CEN

We will set up a process to define key properties of major HPCC machines as an XML database
  • IBM SP, SGI Origin 2000, Cray T3E, Cluster of Workstations/PC's, Tera MT, Sun E10000
  • Many projects currently have competing and incomplete databases which will include properties such as
  • number of nodes, memory size, network QoS, CPU Type ...
A unifying concept for resource database is www.datorr.org which web site(s) will support registration , lookup and display of world's compute resources
  • It will have XML search engine and
  • and a simple interface allowing one to query and display status of registered machines
  • Globus Condor Legion will provide richer interfaces

Foil 19 LMS: Changes in Vegetation

From Review of MAPINT and Gateway at ASC ARL ASC Joint Mid Year Review Aberdeen Maryland -- Feb 23-25 1999. *
Full HTML Index
A decision maker (the end user of the system) wants to evaluate changes in vegetation in some geographical region over a long time period caused by some short term disturbances such as a fire or human's activities.
  • One of the critical parameters of the vegetation model is soil condition at the time of the disturbance.
  • This in turn is dominated by rainfalls that possibly occur at that time
Components of Application Include:
  • Data retrieval
  • Data preprocessing
  • Simulation: two interacting codes
    • EDYS
    • CASC2D
  • Visualization
