Grid Interoperability ShootoutGridPP and NGS

• GridPP 19 Ambleside
• 29-31 Aug 2007

2
Differences

• Physics
• Built for physics UCs
• SL4 (SLC4)
• gLite
• SRM
• ssh

• Non-physics
• Built for non-p UCs
• Various OS
• Globus, Condor,
• SRB
• GSISSH

3
Differences

• Command line
• Supported by specialised groups
• Big data volumes
• No need for secrecy

• Portals cmd line
• Supported by a single (loose) group
• Not so big data vol.
• Some confidential

4
The UI

• Site UIs
• User installable UI
• OS dependent

• Portals
• Specialised portals
• Workflow
• Or use GSISSH
• OS independent

5
Common stuff

• The CA
• MyProxy
• VOMS (sort of)
• BDII GLUE schema

• Big VO, small VO

6
Opportunities
7

• Need for capability computing
• GridPP has high priority for ops
• Data catalogues, file transfers
• Documentation

8

• Portal work
• GSISSH
• Research of the month
• ETF (or ETFs experience)
• Documentation, Training
• User group meeting

9

• How to make grids interoperate
• Standards
• Strong Expertise in UK(I)
• Influence external projects (priorities)

10

• Externalities
• EGEE
• OMII UK/Europe
• EGI and suchlike

• Standards
• OGF
• W3C
• OASIS
• Specialised industry or academic stds (e.g.
  archives)

15
MPI

• NGS providing MPI
• Took some effort
• NGS benefited from (and worked with) GridIreland
• Select MPI jobs via globus-job-submit

16
The ETF

• Engineering Task Force
• http//www.grids.ac.uk/ETF/ (out of date)
• Evaluates middleware
• E.g., SGE, DPM, Unicore,
• DPM was recommended as a useful storage solution

Conclusions

• Opportunities for collaboration
• Build on common areas
• Many individual areas
• Strong expertise in UK in many fields
• Sometimes there are differences for a reason
