A Success

“The achievement of

something desired, planned, or

attempted”


Executive Summary I

• “The GridPP1 Project is now complete: following 3 years of development, a prototype Grid has been established, meeting the requirements of the experiments and fully integrated with LCG, currently the World’s largest Grid. Starting from this strong foundation, a more complex project, GridPP2, has now started, with an extended team in the UK working towards a production Grid deployed for the benefit of all experiments by September 2007.”

• We achieved (almost exactly) what we stated we would do in building a prototype…


Executive Summary II

• “2004 was a pivotal year, marked by extraordinary and rapid change with respect to Grid deployment, in terms of scale and throughput. The scale of the Grid in the UK is more than 2000 CPUs and 1PB of disk storage (from a total of 9,000 CPUs and over 5PB internationally), providing a significant fraction of the total resources required by 2007. A peak load of almost 6,000 simultaneous jobs in August, with individual Resource Brokers able to handle up to 1,000 simultaneous jobs, gives confidence that the system should be able to scale up to the required 100,000 CPUs by 2007. A careful choice of sites leads to acceptable (>90%) throughput for the experiments, but the inherent complexity of the system is apparent and many operational improvements are required to establish and maintain a production Grid of the required scale. Numerous issues have been identified that are now being addressed as part of GridPP2 planning in order to establish the required resource for particle physics computing in the UK.”

• Most projects fail in going from prototype to production…

• There are many issues: methodical approach reqd.

UK Grid

The whole is better than the sum of the parts..


ApplicationsThere is a (slightly wonky?)

wheelUse it to get to where you need

to beZEUS uses LCG•needs the Grid to respond to increasing demand for MC production• up to 6 million Geant events per week on Grid since August 2004

1. The system developed for the large LHC experiments works (more) effectively for other (less resource-intensive) applications

2. Experiments need to work together with deployment team/sites

3. The de-facto deployment standard is LCG – it ~works. We can add components as required, to meet each experiment’s needs
