"Raw" reconstruction setting up - stagein from tape using 1-2 drives 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk. Monte Carlo from Tier 2 incoming sent on to CERN. Test Tier 2 to Tier 1 transfers at 10 MB/sec per Tier 2. Last 2 weeks take 'raw' data from CERN to tape at 20 MB/s Get 2.0 MB/sec of "raw" data from CERN and store 5 TB to tape. Reconstruct and strip these data on 21.5 KSi2K of cpu. Provide 172.5 KSi2K of cpu for MC event generation with 6.5 TB to tape CERN background disk-disk top up to 200 MB/sec
August Continue the July export tests until the 60 MB/s rate has been reached for a sufficient period. Provide 114 KSi2K of cpu for MC event generation. Two slots of 3 days of "raw" reconstruction - stagein from tape using 1-2 drives. Analysis tests - 20 MB/sec incoming - will include scalability tests and prefers to be only Atlas grid activity. T0 to T1 tests take 33.6 MB/sec "Raw" to tape (rate to be reported), ESD at 21.0 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 74.6 MB/s). These data can be deleted after 24 hours 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk. Monte Carlo from Tier 2 incoming sent on to CERN. Test Tier 2 to Tier 1 transfers at 10 MB/sec per Tier 2. Last 2 weeks (after high rate T0-T1disk-disk tests) take 'raw' data from CERN to tape at 20 MB/s (data can be deleted after 24 hours). Analysis of reconstructed data. Provide 194 KSi2K of cpu for MC event generation with 6.5 TB to tape CERN background disk-disk top up to 200 MB/sec
September Scheduled analysis tests. Provide 114 KSi2K of cpu for MC event generation. T0 to T1 tests take 33.6 MB/sec "Raw" to tape (rate to be reported), ESD at 21.0 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 74.6 MB/s). These data can be deleted after 24 hours 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk. Till mid-September take 'raw' data from CERN to tape at 20 MB/s (data can be deleted after 24 hours). From mid-September ramp up to 1 October start of CSA06 at 750 jobs/day (requiring 180 KSi2K of cpu and a total of 70 TB of disk storage). Provide 194 KSi2K of cpu for analysis of reconstructed data and MC event generation with 5.5 TB additional data to tape CERN background disk-disk top up to 200 MB/sec.
October Continue the data export tests until the 60 MB/s rate has been reached for a sufficient period. Scheduled analysis tests. Reprocessing tests - 20 MB/sec incoming 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk.
