ATLAS Distribution of activities over 2007

Month Atlas Requirements
April 2006 Internal Tier 0 tests (may now include external components - under discussion). Distributed production of 7M MC physics events and 2.5M single particles requiring 2500 KSi2K. Approximately 40% at T1 sites with slightly different site percentages to the above and 60% at T2 and T3. Events stay on T1 and T2 disks.
May Distributed production of 7M MC physics events and 2.5M single particles requiring 2500 KSi2K. 40% at T1 sites
June 29 May to 4 June ramp up file transfers to Tier 1 sites to 25% of June 19 target. 5 June to 11 June ramp up file transfers to Tier 1 sites to 50% of June 19 target. 12 May to 18 June ramp up file transfers to Tier 1 sites to 75% of June 19 target. 19 June till 7 July send 772 MB/sec "Raw" (at 320 MB/s), ESD (at 252 MB/s) and AOD (at 200 MB/s) from Tier 0 to Atlas Tier 1 sites, a total of 90K files per day. The "raw" to go to tape which must be unloaded before tapes are recycled and the data rate to tape should be reported. All disk and tape data can be recycled after 24 hours. Distributed production of 7M MC physics events and 2.5M single particles requiring 2500 KSi2K. 40% at T1 sites
July Continue the data export at 772 MB/sec for the whole of July. Distributed reconstruction setting up using local stagein from tape (1-2 drives required). Continuous distributed production of 2M MC events/week requiring 2700 KSi2K. 40% at T1 sites with slightly different site percentages to the above
August Continue the data export at 772 MB/sec for the whole of August.Two 3-day slots of distributed reconstruction using local stagein from tape (1-2 drives required). Distributed analysis tests - 20 MB/sec incoming at each Tier 1 - will include scalability tests and prefers to be only Atlas grid activity. Possibly pause the continuous distributed production of 2M MC events/week
September Tier 0 internal tests. From mid-September continuous distributed production of 2M MC events/week requiring 2700 KSi2K. 40% at T1 sites. Repeat June Tier 0 raw data processing and raw data plus ESD plus AOD export to Tier 1 sites at 772 MB/sec. Scheduled for mid-September and to last 2-3 weeks.
October Distributed reprocessing tests - 20 MB/sec incoming at each Tier 1. Continuous distributed production of 2M MC events/week requiring 2700 KSi2K. 40% at T1 sites
November Distributed analysis tests - 20 MB/sec incoming at each Tier 1 at the same time as distributed reprocessing continues. Continuous distributed production of 10M MC events/month requiring 3246 KSi2K of which 40% to be at T1 sites. An additional 22 TB of permanent disk and 20 TB of temporary (till reconstruction is run) disk plus an additional 32 TB of tape storage are required over the T1 sites.
December Continuous distributed production of 10M MC events/month requiring 3246 KSi2K of which 40% to be at T1 sites. An additional 22 TB of permanent disk and 20 TB of temporary (till reconstruction is run) disk plus an additional 32 TB of tape storage are required over the T1 sites.
