Atlas:Functionnal-test-lyon-oct06
The goal of this test is to check that data produced can be moved between sites (functionnalities are working). It is not a performance measurement yet.
News and actions
- Check disk space availability in LYONDISK (300 GB) and Tier2S (100-200 GB)
- 15 October : Start of the test
Summary
mail from Alexei Klimentov (7 October 2006)
- The next DDM functional test is scheduled for October 2006 after SC4
- We will start to generate data in a week from now (Oct 15th)
- Please update table 'Sites' (DDM ops WiKi Functional test) for your site. Data will be generated only for the sites listed in the table. (DDM ops WiKi : https://twiki.cern.ch/twiki/bin/view/Atlas/DDMOperations)
- Test duration 7 - 10 days
- The test scope (preliminary) :
- repeat Step1 and Step2 of the previous test
- Step 1: CERN->Tier1->Tier2s data transfer
- Step 2: Tier2s->Tier1 data transfer
Bulk data transfer
- CERN -> Tier1s
- Tier1->Tier2s (2-3 Tier-2s per cloud)
- Data transfer of large 2+GB files (if available)
- Evaluation of data transfer robustness vs dataset size
- FTS open access (data transfer between different clouds)
- Two more functional tests are already scheduled Year 2006 (week 47-48, TBC), and Jan 2007. Probably in January we will try to evaluate data transfer performance.
- several suggestions, comments, questions
- will we use DDM ops mailing list to discuss test scope or HyperNews ?
- Tier-1s will need 200-300GB disk space for the October test
- Tier-2s (if they will participate in bulk data transfer) will need 100-200 GB disk space for the October test
- There are no special requirements for the SW installation. Run what you are using for SC4
