UK & Japan N+N Meeting @ The Montague Hotel, London 3rd Oct. 2003

Overview of Grid ASP

Grid ASP provides users PSE( Grid services )Portal system hides Grid environment from users

UserGridASP(Grid Service Provider)

PSE components(Grid Services)•Application service•Storage service•Computing service•DB service :

Portal

Main service is a batch job

3


Activities @ GTRC, AIST

Software toolkit for constructing portalGrid PSE Builder (GridLib)

Grid application portalsISV software( Gaussian, Phoenics, ... )user programming application

Experiment of Grid ASP (planning)Feasibility study with real business players

4


Overview of the Grid PSE Builder

Framework for building an application portal on a grid environment

Globus Toolkit 2.x (MDS, GRAM, GSI)

5


Single-sign-on/session manager

SSL client server mutual authentication Session management at SSL/TSL layerX.509 certificate based client authentication

Proxy certificate based on GSI using portal ID( Single user account on grid environment )

Batch job / Data staging manager

In/Out file management for jobsUpload and download input parameters and files between client and PortalTransfer files from portal server to specified resources using GridFTP

Job execution managementSubmit/ cancel jobs using globus GRMMonitor status of jobs

Future work for Grid PSE Builder

Individual accounting modelProxy certificate for individual userUsers don’t need globus on their clients

Workflow controlUser : describe workflow of their jobsProvider : combine several applications as a single service
