Summary: HEP CG WP3 Distributed Interactive Data Analysis
Partner: LMU (Atlas), GSI (Alice)
unfunded: Uni Karlsruhe (CMS), MPI Heidelberg (LHCb), LRZ, MPI M, RZ Garching
Optimise application specific job scheduling
Analyse and test of software environment required
Job management and Bookkeeping of distributed analysis
Distribution of analysis, sum-up of results
Interactive Analysis:
Creation of a dedicated analysis cluster
Dynamic partitioning of Grid analysis clusters

3. Start with Gap Analysis
LMU:
Investigating Job-Scheduler requirements for distributed and interactive analysis
GANGA (ATLAS/LHCb) project shows good features for this task
Used for test MC production on LCG
J. Elmsheuser
GSI:
Analysis based on PROOF
Investigating different versions of PROOF clusters

“static” use of resources
jobs frozen: 1 job / worker node
“manual” splitting, merging
limited monitoring (end of single job)

farm perceived as extension of local PC
same macro, syntax as in local session
more dynamic use of resources
real time feedback
automated splitting and merging

6. Deliverables: Interactive Analysis for Atlas: LMU advanced
Interactive Analysis for Alice: GSI advanced
Automated Jobmanagement System: LMU on track
Application specific Scheduling: GSI in a very early stage, we learned a lot during this WS
