Milestone |
Date |
|
1 |
Baseline plan for Phase 2 agreed (Tier-0 & Tier-1s) |
October 2004 |
|
|
A document will describe the level of service to be provided by the Tier-1 and Tier-0 centres. This document will provide the basis for the TDR and for the MoUs. |
|
|
2 |
Agreed AA 1-2 year development & support plan available. |
May 2004 |
|
|
With the LCG-funding of manpower in the applications area running down during 2004 and 2005, a plan is required to establish the level of support that is required for the products that are essential for the experiments. This plan will lead to the definition of more detailed milestones. |

AA development & support plan & resources through 2008 |
September 2004 |
|
|
Same as above with a longer term view. |

4 |
Distributed batch environment using grid service - four experiments using LCG-2 level of functionality – (general service beyond centralized MC production) |
December 2004 |
|
|
Reliable service capable to do data movement, synchronizing metadata catalogues |
|
|
5 |
Distributed end-user interactive analysis prototype ARDA available and successfully tested in four experiments |
December 2004 |
|
|
Four instances of end-to-end solutions implementing the ARDA middleware into the experiments’ frameworks are operational in the form of prototypes. |
|
|
6 |
Coherent operation of the LHC computing Tier-1 centres |
July 2005 |
|
|
The Tier-1 centres for LHC computing have installed middleware that operates such that for the end user physicists it appears as a single system providing transparent access to all allocated resources. |
|
|
7 |
Computing service TDR |
July 2005 |
|
|
The Computing Service TDR will specify the requirements for the Grid that will be used for the first production services for the four LHC experiments. It will include details of the architecture, functionality, capacity, performance, throughput and availability. It will include the Regional Centre plans that will have been developed to meet these requirements, and will provide cost estimates and an overall installation and verification schedule. It is assumed that the TDR will be approved by the LHCC within three months following its availability, and may be used to provide data for the Memorandum of Understanding for Phase 2 of the project. The full process from acquisition to service verification is expected to take 12-18 months (according to the administrative procedures of the Regional Centres). The initial service must be in full production by September 2006 (6 months before data taking). The TDR will therefore be approved after the acquisition procedures have started, but before orders are placed. |

Initial production LCG middleware providing the functionality for the first LHC data taking in operation (Tier-0, Tier-1 Tier-2) |
April 2006 |
|
|
The middleware required for the first data taking at LHC must be available at Tier-1 and Tier-0 centres one year before the start of the run. |
|
|
11 |
Initial LCG system functionality for first LHC run complete (T0&T1s) |
October 2006 |
|
|
Tier-1 and Tier-0 centres are fully operational and prepared to increase the capacity as required for data analysis. |
