Submitting Belle2 jobs from KEK and UVIC

Login into KEK (login and computer systems) or the belleuser VM on beaver

ssh sshcc1.kek.jp
ssh login.cc.kek.jp

Running interactive jobs

source /cvmfs/belle.cern.ch/sl6/tools/setup_belle2
setuprel release-00-07-02
cd working/basf2/
cp /cvmfs/belle.cern.ch/sl6/releases/release-00-07-02/reconstruction/examples/example.py .

Add the following lines into the example.py script:

from ROOT import Belle2
use_local_database(Belle2.FileSystem.findFile("data/framework/database.txt"), "", True, LogLevel.ERROR)

Run the MC generation example job from the command line

basf2 ./example-new.py
(note that the "new" version has extra lines for a database fix)

Run the Analysis example job (my_ana.py) from the command line.

(belleuser)$ setuprel release-00-07-02  (required for this data set)
(belleuser)$ basf2 ./my_ana.py -i ~/mdst_000113_prod00000223_task00000113.root

(kek)$ basf2 ./my_ana.py \
-i /ghi/fs01/belle2/bdata/MC/release-00-07-02/DBxxxxxxxx/MC7/prod00000223/s00/e0000/4S/r00000/signal/sub00/mdst_000113_prod00000223_task00000113.root

Running grid jobs

Initialization of Belle2 environment

(belleuser)$ source /opt/gbasf2KEK/BelleDIRAC/gbasf2/tools/setup
(kek)$ source /sw/belle2/gbasf2/BelleDIRAC/gbasf2/tools/setup

gb2_proxy_init g belle

Run example job on the grid

cd working/gbasf
(belleuser)$ gbasf2 example.py -p myproject -s release-00-07-02 

Add option to run on UVIC cloud (--site=DIRAC.UVic.ca)

Locate the data samples

gb2_ds_list /belle/MC/release-00-07-02/DBxxxxxxxx/MC7/prod00000223/s00/e0000/4S/r00000/signal/sub00

Run the analysis example job on the grid (over 100 jobs are submitted, one per mdst file)

cd working/gbasf2
gbasf2 ./my_ana.py -p rjs1 -i /belle/MC/release-00-07-02/DBxxxxxxxx/MC7/prod00000223/s00/e0000/4S/r00000/signal/sub00
(same command on belleuser or kek)

Monitoring the jobs

gb2_job_status -p <ProjectName> --site DIRAC.UVic.ca 
gb2_site_summary --site DIRAC.UVic.ca --date 2016-04-10
gb2_job_status --site DIRAC.UVic.ca --status Waiting
