E-SCIENCE IN THE ARTS AND HUMANITIES: AN EARLY ADOPTERS’ FORUM NCSA, 1&2 June 2007

VOs for the Arts and Humanities: A shopping list Web 2.0 and the Grid - ‘mashups’ - infrastructural diversity - Interactive infrastructure Formal methods for defining, storing and accessing (i.e. reusing) workflows Project management Training Legal Reporting and documenting failure Development and enrichment of the relationship between A&H and Computer Science International coordination and collaboration Dealing with computational, semantic and human heterogeneity

Web 2.0 and the Grid

- ‘mashups’ - infrastructural diversity

- Interactive infrastructure

Formal methods for defining, storing and accessing (i.e. reusing) workflows

Project management

Training

Legal

Reporting and documenting failure

Development and enrichment of the relationship between A&H and Computer Science

International coordination and collaboration

Dealing with computational, semantic and human heterogeneity

Supporting collective research – virtual organizations

Foster/Kesselman: Virtual Organisation scenarios Highly multidisciplinary simulation with several proprietary software components Thousands of researchers at hundreds of laboratories work together on the same design and pool their resources A large scale computer game with multiple interacting virtual worlds Different number and types of participants, types of activities, scale of interaction and sharing of resources Common: Mutually independent participants would like to work together and share what they have VO: A set of institutions and/or individuals defined by resource sharing policies

Highly multidisciplinary simulation with several proprietary software components

Thousands of researchers at hundreds of laboratories work together on the same design and pool their resources

A large scale computer game with multiple interacting virtual worlds

 

Sharing relationships can vary over time Access rights Resources involved Participants Peer-to-peer Different usage of the same resource, no a priori definition Implementation must be flexible and user controlled in terms of varying policies, identities etc. Delegation of authority Some initial challenges

Sharing relationships can vary over time

Access rights

Resources involved

Participants

Peer-to-peer

Different usage of the same resource, no a priori definition

Implementation must be flexible and user controlled in terms of varying policies, identities etc.

Delegation of authority

VOs in Grids Ability to negotiate resource-sharing arrangements and then to use the resulting resource pool for some purpose. (Ian Foster)

Grid: VO management Before VOMS Remember the way to Athens User is authorized as a member of a single VO All VO members have same rights VOMS User can be in multiple VOs Aggregate rights VO can have groups Different rights for each Nested groups VO has roles Assigned to specific purposes

Before VOMS

Remember the way to Athens

User is authorized as a member of a single VO

All VO members have same rights

VOMS

User can be in multiple VOs

Aggregate rights

VO can have groups

Different rights for each

Nested groups

VO has roles

Assigned to specific purposes
