Minutes of the GGF-9 Session 

Introduction and Business: 

Judith Utley opened the meeting and introduced the Intellectual Property statement. The group needs a Secretary. Ian 
Bird agreed to serve temporarily. 

Judith briefly discussed the direction of PGM-RG: Complete the documents that the group committed to at GGF-6. By taking
 the writing of these documents outside of the sessions will help to move these documents forward faster as well as free
 time for new issues of concern to the group. By making use of gridforge for drafts and circulation everyone the group 
can review the work being done. GGF meetings will be used to host workshops and leave sessions open to discuss current 
issues related to grid management. PGM should host at least one workshop a year. 

Best Practice document status: 

There have been problems finding authors with time to devote to this work. Some authors who wanted to contribute found 
they had copyright issues. These concerns have been resolved. The Best Practice document can refer to papers the author 
or others have published elsewhere. 

Another problem is that potential authors are asking for an outline. Three outlines have been presented. None were 
accepted. The group voted earlier to not use outlines, giving authors more freedom. This is creating a document that is 
becoming too large. Judith is trying to cut this down as well as give authors the freedom that some believe is required.
 Each section will now have an outline of areas to cover; more of a summary of the topic. Links to other, perhaps longer
 documents, produced both internally or externally can be referenced. This seems to be a compromise between producing a 
document that will be accepted and still allow authors the freedom that some in the group believe they should have. The 
group agreed to this approach. 

Contributions for the document so far: 
Doru Marcusiu on accounting at GGF9 
John Towns on User Services for GGF9 
Steve Chan on security for GGF8 
Bruce Barkstrum on capacity management for GGF8 
Judith is pulling this document together as the document editor 

Doru Marcusiu Grid Account Management (presentation and discussion) 
Doru presented a case study on Grid Account Management to illustrate various aspects of what is meant by account 
management, and accounting as well as showing existing solutions and suggestions for the future. 
Goals for Grid Account Management: 
Salability 
Non intrusive interface to existing policies/services? 
Dynamic 
Secure 
Extensible 
Automation 
What is accounting? 
Collection, collation and reporting of resource usage 
Multiple accounting systems need to be coordinated 
Tracking by DN 
Distributed, cross-domain resources 
There was a discussion on who is responsible for DNs being unique. It was clear in the discussion that this must be the 
CA even if the CA is part of the grid operation (and is unique). In the general case where a grid accepts several CAs, 
uniqueness within a CA guarantees uniqueness in the grid. 

Grid account management issues: 
Each site has account management system and policies 
Must work without central authoritative source of information 
Use std extensible exchange mech 
Support management of cert DNs 
Questions on multiple DNs to 1 account means cannot have definite account reporting; - would need to track which DN maps
 to local account + policy issues e.g. at DOE sites 


Doru commented that there would probably never be a need for cross-domain resources, but in fact this will already be 
essential for projects such as EGEE. There was a discussion on mapping of users to accounts vs job level mapping. Try to
 avoid multiple credentials. A focus on supporting a single organization grid was seen as too simplistic. There was 
agreement that it is essential to keep informed on standards. 

Various different accounting systems already exist (discussion) and no one-size-fits all exists there should be several 
case studies to illustrate different possibilities in different...
