Overview

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


Information and organization

Information and organization

Mailing list:

  • [email protected]

    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


Testbed0

Testbed0

  • Objective: deploy basic Globus services and test them


Procedure for participating institutes

Procedure for participating institutes

  • CERN, Lyon, Marseille, RAL, INFN Bologna, Liverpool, Edinburgh, Imperial, Nikhef

  • others interested please contact me


Planning of tests admin

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


Planning of tests what to test

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


Planning of tests how to do it

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


Status so far

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


Timescale

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
