Last Updated 31.7.2007: Add plans for Atlas M4 cosmics run 23 August to 2 September.

Updated 25.06.2007: Split off 2006 plans into a separate linked page and remove LHC engineering run.

Updated 05.06.2007: Add in 3D database disk and server requirements and ATLAS quantitative requirements for 3Q.

Updated 6.3.2007: Add plans for ALICE p-p dress-rehearsal.

Updated 28.02.2007: Precise plans for Atlas February/March Data Distribution tests (see https://twiki.cern.ch/twiki/bin/view/Atlas/TierZero20071). Change Atlas share from 5.5% to 4.5%.

Updated 15.01.2007: Move the ATLAS Tier0 export tests from 15 Jan to new preliminary date of end Feb.

Updated 17.11.2006: For ATLAS revise (downwards, especially in disk) MC requirements for first half of 2007.

Updated 2.11.2006: For ATLAS revise 4Q2006 MC requirements, add MC plans up to mid-2007 and add January 2007 Tier-0 and export exercise.

Updated 27.10.2006: for ALICE add resource requirements for all of 2007.

Updated 21 August to continue ATLAS data export plan till end September. Currently NDGF is in a reorganisation phase and is not providing resources for LCG.

Updated 12 June to update Atlas June plans.

NDGF-Nordic Data Grid Facility Site Resource Requirements Timetable for 2007

Tier 1 NDGF- 3 Sites. To provide 9% of ALICE Resources (from 2007) To provide 4.5% of ATLAS resources  
Month ALICE Requirements ATLAS Requirements Tier 0 Requirements
January 2007 During first quarter build up to a data challenge of 75% of the last quarter (data taking) capacity using new site capacity as and when available. Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Provide 95 KSi2K of cpu each month and an additional 5.5 TB of permanent disk plus an additional 4 TB of permanent tape storage for this quarter for MC event generation. CERN background disk-disk top up to 60MB/sec
February During first quarter build up to a data challenge of 75% of the last quarter (data taking) capacity using new site capacity as and when available. Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Provide 95 KSi2K of cpu for MC event generation. CERN background disk-disk top up to 60MB/sec
March During first quarter build up to a data challenge of 75% of the last quarter (data taking) capacity using new site capacity as and when available. Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. From 26 March for 7 days participate in WLCG multi-VO 65% milestone so import at 7 MB/s from CERN. Provide 95 KSi2K of cpu for MC event generation. Preliminary plan: from 12 March begin 2 week data distribution tests. Rampup to full 2008 rate from Tier 0 during first week. Raw from Tier 0 to reach 14 MB/s, ESD to reach 18 MB/s and AOD to reach 20 MB/s. Raw data to go to tape then can be recycled. ESD and AOD to go to disk and can be recycled but during last two weeks AOD should be distributed to associated Tier 2, requiring up to 5.2 TB of disk buffer, before being recycled. From 26 March participate in all-experiment service challenge milestone taking 65% of the average 2008 rate as above but without AOD redistribution for the next 7 days. CERN background disk-disk top up to 60MB/sec
April Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Starting in April and continuing throughout the year build up to full-scale dress rehearsal of p-p running with raw data (at 11 MB/s) and ESD (an additional 10% of the raw) import from CERN, reconstruction at Tier-1 and user analysis and simulation at Tier-2. The data are to be stored in a Tape1Disk1 class storage but where ALICE will manage the disk space. Provide 190 KSi2K of cpu each month and an additional 11 TB of permanent disk plus an additional 8 TB of permanent tape storage for this quarter for MC event generation. Provide a permanent 300 GB of disk space and 3 DB servers for ATLAS conditions and event tag databases. CERN background disk-disk top up to 60MB/sec
May Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Provide 190 KSi2K of cpu for MC event generation. Repeat February/March data distribution tests. CERN background disk-disk top up to 60MB/sec
June Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Provide 190 KSi2K of cpu for MC event generation. CERN background disk-disk top up to 60MB/sec
July Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Start preparations/testing for full scale (2008 running) dress rehearsal. CERN background disk-disk top up to 60MB/sec
August Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Continue rampup of full scale dress rehearsal. From 23 August to 2 September take M4 cosmics data from Tier 0 for 50% of this time: peak rates of raw data at 6 MB/s, esd at 1 MB/s and whole aod at 4 MB/s. Total of 3 TB of raw to go to tape for recall in September reprocessing. Total of 3TB of esd+aod to go to permanent disk with aod redistribution to requesting Tier2. All data to be kept until M6 cosmics run at the end of December 2007. See PlanningM4 CERN background disk-disk top up to 60MB/sec
September Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Reach rates of full scale dress rehearsal. Take raw data from CERN (raw is to go to tape) at 14.4 MB/sec, ESD at 18 MB/sec and AOD at 20 MB/sec. Send and receive data from Tier-1 and Tier-2 according to the Megatable spreadsheet values (see link on first page of this Twiki). CERN background disk-disk top up to 60MB/sec
October Require up to 482 KSi2K cpu, 120 TB disk and 213 TB tape over NDGF. Export rate from CERN to NDGF will be 38 MB/s. Stable running of full scale dress rehearsal. CERN background disk-disk top up to 60MB/sec
November For eventual Data Taking startup require 643 KSi2K cpu, 159 TB disk and 284 TB tape over NDGF. Export rate from CERN to NDGF will be 50 MB/s. Provide a permanent 1000 GB of disk space and add DB servers if needed for ATLAS conditions and event tag databases. CERN background disk-disk top up to 60MB/sec
