Notes of the meeting of the Applications Research Group (APPS-RG),
held at GGF9 in Chicago, October 6, 2003
Notes taken by: Shantenu Jha, <s.jha@ucl.ac.uk>
Session chaired by: Thomas Hinke
Introduction:
Reviewed goals of APPS-RG, as discussed at [Oct 2002, GGF6]
1. Goal: Apps Workshop
Reviewed accomplishments e.g. GGF5 in Glasgow, GGF7 in Tokyo andGGF8 in Seattle.
One thought- In general, summer GGF for workshops
Simon Cox: Should we investigate possiblity of holding WS inFrankfurt with GGF10? (rationale similar to Tokyo).
Action Item: Simon Cox to contact Mark Parsons for one lastattempt at organizing a WS at GGF10 (Frankfurt).
Ray Bear: Challenges of Large Applications in DistributedEnvironments [CLADE]. Lastyear was published seperate to HPDC (held in Seattle). Hinke: Do we needanother WS if CLADE is already happening in the time frame of Honolulu?
Rob Hood: Mentioned UPDT will be having a WS at GGF11.
Cox: If jointly done with CLADE, usual registration relatedproblems.
Hinke: 1 workshop a year, logistics- offsite? venue?
Cox: Possibility of any off-track events to be held at NeSC(Edinburgh,UK)
Dave Berry seconded it.
Hinke: Closing remarks: needs further thought.
2. Goal: Grid technology assessment
"Build a set of grid applications to evaluate the currentstate of the grid and document the results. Collect statistics of current gridstatus with links to different grids... "
Demo-based Grid Assessment Issues:
Need clear objective and assoc. metric for demo such as one ormore of the following:
e.g. Ability toeasily use grids
???
Desirable:
....
Discussion:
Where do we want to go with this?
Volunteers to lead and contribute?
** Don't do anassessment **
3. Case Studies
Collect case studies of grid applications with a focus on what theapplication does and how it uses the grid to accomplish its goals.
Collect 3 types of case studies:
Make recommendations that go back to the other GGFresearch/working groups
Cox: make the case studies as a basis for the workshop; anddocument derived from individual contributions for the workshop.
classification: compute intensive, data intensive...
Franz: contributeenvironment risk analysis
MPI code, weather
Peggy: industrial application (engineering) used at EFBL, France.
Kum Won Cho : CFD
** consensus: explorepossibility of having this in Frankfurt. **
Dave Barry: mentioned OGSA use case document. Explore overlap?
Action: Dave Barry to dig out the template of the OGSA Use caseand email to some people...
4. Goal: Identitify and assess burning issues that applicationdevelopers have that could either facilitate or hinder the development of gridapplications
Hinke: GT3 problems (Astronomy BoF)
Susan: insufficient documentation
5. Goal: Application-unique requirements --
discussion: mailing list.
what do we expect to come out of the mailing list?
6. Goal: Identify and classify application-orientedcapabilities that grids currently facilitate
Cox: to be used in an executive summary?
Hinke: What else would people have liked to see?
concentrate not so much on the application but focus on the gridtechnology e.g. used globus run, grid-ftp.
Hinke: quickpresentations not necessarily in a workshop context
Remarks: Best practises possible only when 'hardened architecture'
Hinke: not necessarily 'best practises', but 'a practise'?
e.g. which grid commands
Remarks: akin to design patterns, which are best practises fromcommonly recurring problems
e.g. recurring problem: job submission (JS)
possible solution: JS service factory
** Use APPS-Gas a forum for discussion between end users and tool
developers.Structure meetings like a show and tell?**
