pid_scripts

Quick information

---

It is a simple example of scripts/macros sets suitable for work on the MEPhI (basov) cluster.

Setting environment

Copy from a git repo:

    git clone https://devel.mephi.ru/PEParfenov/pid_scripts.git

Change paths accordingly:

• 1 In set_env.sh: Change ST_FEMTO_DST_INC_DIR to standard one. It's the directory where libStFemtoDst.so is stored.
• 2 In scripts/run.sh: change path to a last line to one where your build will be.
• 3 In scripts/start.sh: change path to output directory (OUTPUT_DIR).

Installation

Source required environment variables:

    cd pid_scripts/
    . set_env.sh

Make new build directory. For example:

    mkdir build/
    cd build/

Generate makefile & install:

    cmake ../macro/
    make

Keep in mind that one has to do make command after changing FemtoDstAnalyzer.C in order to compile new code.

Generate filelists

Use GenerateLists.sh to make filelists:

    . GenerateLists.sh FEMTODST_DIR N_FILES_IN_LIST

where FEMTODST_DIR - path to the directory with femtoDst.root files. And N_FILES_IN_LIST denotes the maximum number of femtoDst.root files in each filelist. Basic example:

      . GenerateLists.sh /mnt/pool/rhic/2/nigmatkulov/femtoDst/auau/200gev/12135/ 100

Resulting filelists will be in the hpc_scripts/lists/ directory.

Usage

Interactive mode

To use FemtoDstAnalyzer_PID.C in interactive mode:

    cd build/
    ./pid -i INPUTFILE -o OUTPUTFILE

To use FemtoDstAnalyzer_PID.C in interactive mode:

    cd build/
    ./pid -i INPUTFILE -o OUTPUTFILE -pid PID_FILE

where INPUTFILE - is input file or filelist with femtoDst.root. OUTPUTFILE - is resulting root file and PID_FILE - is fitted sigma values in m^{2} distribution. Basic workflow example:

    ./pid -i ../lists/StRuns1.list -o ./test_pid.root
    root.exe '../macro/CalcPID.C("test_pid.root","test_pid_fit.root",1)'
    ./pidQA -i ../lists/StRuns1.list -o ./test_pid_QA.root -pid ./test_pid_fit.root

Batch mode

To send jobs to basov cluster, use scripts/start.sh:

    . start.sh INPUT_FILELIST_DIR MODE_NUM

where INPUT_FILELIST_DIR - is the directory where you store filelists. MOD_NUM - is mode number: 0 - run pid, 1 - run pidQA. Basic example:

    . start.sh /mnt/pool/rhic/4/parfenovpeter/STAR/Analysis/pid_scripts/lists 0
