Month ALICE Requirements ATLAS Requirements LHCB Requirements (See LHCb070529.xls) Tier 0 Requirements
March 2006        
April   Provide 134 KSi2K of cpu for MC event generation and 8 TB of disk and 20 TB of tape for MC data for this quarter Provide 75 KSi2K of cpu for MC event generation 3rd to 16th CERN disk-disk at 150 MB/sec. 18th to 24th CERN disk-tape at 75MB/sec
May   Provide 134 KSi2K of cpu for MC event generation Provide 75 KSi2K of cpu for MC event generation CERN background disk-disk top up to 150 MB/sec
June   Provide 134 KSi2K of cpu for MC event generation. From 19 June to 7 July T0 to T1 tests take 41.6 MB/sec "Raw" to tape (rate to be reported), ESD at 26.0 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 87.6 MB/s). These data can be deleted after 24 hours Get 5.3 MB/sec of "raw" data from CERN and store 5 TB on tape. Reconstruct and strip these data on 21.5 KSi2K of cpu. Provide 53.5 KSi2K of cpu for MC event generation with 2 TB to tape CERN background disk-disk top up to 150 MB/sec
July From 24 July to 6 August take 30 MB/s of raw and ESD data (10% of total) from CERN. These data can be deleted immediately. Provide 145 KSi2K of cpu for MC event generation and 11 TB of disk and 27 TB of tape for MC data this quarter. "Raw" reconstruction setting up - stagein from tape using 1-2 drives Get 5.3 MB/sec of "raw" data from CERN and store 5 TB on tape. Reconstruct and strip these data on 21.5 KSi2K of cpu. Provide 53.5 KSi2K of cpu for MC event generation with 2 TB to tape CERN background disk-disk top up to 150 MB/sec
August Continue the July export tests until the 30 MB/s rate has been reached for a sufficient period. Provide 145 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. Take 41.6 MB/sec "Raw" to tape (rate to be reported), ESD at 26.0 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 87.6 MB/s). These data can be deleted after 24 hours Analysis of reconstructed data. Provide 75 KSi2K of cpu for MC event generation with 2.5 TB to tape CERN background disk-disk top up to 150 MB/sec
September Scheduled analysis tests. Provide 145 KSi2K of cpu for MC event generation. Take 41.6 MB/sec "Raw" to tape (rate to be reported), ESD at 26.0 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 87.6 MB/s). These data can be deleted after 24 hours Provide 75 KSi2K of cpu for analysis of reconstructed data and MC event generation with an additional 2.5 TB to tape CERN background disk-disk top up to 150 MB/sec.
October Continue the data export tests until the 30 MB/s rate has been reached for a sufficient period. Scheduled analysis tests. Reprocessing tests - 20 MB/sec incoming Provide 235 KSi2K of cpu for reconstruction and analysis and MC event generation with an additional 1.4 TB of tape and 0.3 TB of disk. CERN background disk-disk top up to 150MB/sec
November Continue the data export tests until the 30 MB/s rate has been reached for a sufficient period. Scheduled analysis tests. Provide 169 KSi2K of cpu and an additional 2.2 TB of permanent disk and 2.0 TB of temporary (till reconstruction is run) disk plus an additional 3.1 TB of permanent tape storage for MC event generation. Analysis tests - 20 MB/sec incoming at the same time as reprocessing continues Provide 238 KSi2K of cpu for reconstruction and analysis and MC event generation with an additional 2.7 TB of tape and 0.9 TB of disk. CERN background disk-disk top up to 150MB/sec
December Continue the data export tests until the 30 MB/s rate has been reached for a sufficient period. Scheduled analysis tests. Provide 169 KSi2K of cpu and an additional 2.2 TB of permanent disk and 2.0 TB of temporary (till reconstruction is run) disk plus an additional 3.1 TB of permanent tape storage for MC event generation. Provide 384 KSi2K of cpu for reconstruction and analysis and MC event generation with an additional 4.2 TB of tape and 10.3 TB of disk. CERN background disk-disk top up to 150MB/sec
