post-ap 0.1.5

Project with code needed to filter, trim and slim ntuples produced by AP

Description

This project is used to:

• Filter, slim, trim the trees from a given AP production
• Rename branches
• Download the outputs

This is done using configurations in a YAML file and through DIRAC jobs.

Check this for installation instructions and for instructions on how to setup an environment to use this project.

Submitting jobs

Check latest version of virtual environment

All the jobs below require code that lives in a virtual environment, there should be multiple versions of this environment and the latest one should be obtained by running:

dirac-dms-user-lfns -w dcheck.tar -b /lhcb/user/${LXNAME:0:1}/$LXNAME/run3/venv

currently, the latest is 023. Unless you have made your own tarballs, LXNAME=acampove.

Submit jobs

To run the filtering, after properly installing the project, as shown here do:

# Local will create a local sandbox, use wms to send to the grid

# For data, this will process a single PFN locally
job_filter -n test_job -p rd_ap_2024 -s       data -c /home/acampove/Packages/config_files/post_ap/v3.yaml -e 025 -u acampove -m local -t

# For data, this will process all the PFNs in the grid 
job_filter -n data_job -p rd_ap_2024 -s       data -c /home/acampove/Packages/config_files/post_ap/v3.yaml -e 025 -u acampove -m wms

# For MC, this will process all the PFNs in the grid 
job_filter -n mc_job   -p rd_ap_2024 -s simulation -c /home/acampove/Packages/config_files/post_ap/v3.yaml -e 025 -u acampove -m wms

where the options mean:

  -h, --help            show this help message and exit
  -n NAME  --name NAME  Name of job, needed for dirac naming and to name output
  -p PROD, --prod PROD  Name of production, e.g. rd_ap_2024, this shoudl be the same as in the config section.
  -s SAMP, --samp SAMP  Sample nickname found in the config section `samples`
  -c CONF, --conf CONF  Path to config file, which should be a YAML file and a few examples are linked below.
  -e VENV, --venv VENV  Index of virtual environment, e.g. 023
  -u USER, --user USER  User associated to venv, currently acampove should be the only choice, but if you author your own virtual environment and upload it, then this should be your user name
  -d DRYR, --dryr DRYR  If used, submission will be skipped, needed for debugging.
  -M MAXJ, --maxj MAXJ  Maximum number of jobs, default 500. If 1000 PFNs are found, will do 500 jobs, if 100 PFNs are found, will do 100 jobs
  -m {local,wms}, --mode {local,wms} Run locally (for tests) or in the grid
  -t       --test       If used, will send only one job

Regarding the name, the output will go to a directory in EOS named JOBNAME_SAMPLENAME, e.g. test_001_data if -n test_001 is used on the data sample. Some config files can be found here

Downloading ntuples

A test would look like:

run3_download_ntuples -j dec_06_2024_data -n 20 -r 1 -m 5 [-d $PWD/files]

where:

-j: Is the name of the job, which has to coincide with the directory name, where the ntuples are in EOS, e.g. /eos/lhcb/grid/user/lhcb/user/a/acampove/flt_004.
-n: Number of ntuples to download, if not pased, will download everything.
-d: Directory where output ntuples will go, if not passed, directory pointed by DOWNLOAD_NTUPPATH will be used.

A real download would look like:

run3_download_ntuples -j dec_06_2024_data -m 40

Where -m denotes the number of threads used to download, -j the name of the job.
