1. LHCb planning for DataGRID testbed0 Eric van Herwijnen Thursday, 10 may 2001

2. Overview  Information & organization  Testbed0  Procedure for participating institutes: Planning of tests: admin Planning of tests: what to test Planning of tests: how to do it  Status so far  Timescale

3. Information and organization Mailing list:  lhcb-grid@listbox.cern.ch CVS repository:  to get Java production tools: cvs -d $NEWCVSROOT co GRID/productiontools  to get the DataGRID LHCb installation kits: cvs -d $NEWCVSROOT co GRID/installationkits  to get sample script and.dat files: cvs -d $NEWCVSROOT co GRID/scripts

4. Testbed0  Objective: deploy basic Globus services and test them

5. Procedure for participating institutes  CERN, Lyon, Marseille, RAL, INFN Bologna, Liverpool, Edinburgh, Imperial, Nikhef  others interested please contact me

6. Planning of tests: admin  Complete your entry in previous table and contact me (find out exactly what your local testbed0 is from local WP6 contact)  Decide which tests you want to do (e.g. Submit jobs from Bologna to Liverpool)  Get a national Grid certificate following the procedure on http://marianne.in2p3.fr  Get local accounts on the testbeds that you want to test  WP6 will add people to Grid map files

7. Planning of tests: what to test  Objective: run bb-bar inclusive generation and reconstruction job via Globus if possible send data to CERN update the bookkeeping database  For sites wishing to become part of LHCb production: installation of java production tools automate file transfer to CERN

8. Planning of tests: how to do it  Check out GRID files from cvs repository  uncompress (gunzip *.tar.z) and untar (tar -xvf *.tar) the installation kits  run the bbincl.job script, modify it until it works (don’t worry about java to start with)  when it works, do e.g.: globus-job-submit csflnx01.rl.ac.uk/jobmanager-pbs bbincl.job  try to recover output with other globus commands or ftp by hand  to install production tools (requires servlet runner) contact me

9. Status so far  RAL CSF and CERN testbed0 integrated with LHCb production tools  Jobs with 5 events run fine  Larger jobs can be run one at a time, problems with gass_cache under investigation  Problems interfacing to pbs (jobs always end up in M queue)  Problems with using sh or csh

10. Timescale  Tests of testbed0 should be done before september 2001 (testbed1 release)  LHCb Grid meeting Bologna 13-15 june 2001 progress on testbed0 tests security issues for testbed1 LHCb analysis model
