NA62 Monte Carlo Simulations

This wiki describes how to set up and distribute the NA62 Monte Carlo simulation code.

Software

• Test tarball from Antonino Sergi: NA62MC.tar.zip

Code compilation

• Unpack tarball to NA62MC
• Fix libs path problems in GNUMakefile-s (Generator/ and Beam/)
• Make changes to env.sh: source 'offline' environment; clear XAWLIBS variable
• Rearrange paths (move system paths after NA62-specific paths)
• Type 'make' and be patient

Code distribution

• Create tarballs for geant4, root, X11 and sw (CreateTarballs.sh)
• Run special job (with an SGM Admin role) to wget and unpack these tarballs on sites (InstallSoftware.sh)
• Run test job

Job submission

• Run parameters given in the StandardRun.mac file: run number, number of events, random seed, root output file name
• Job environment parameters are set by sourcing the na62jobenv.sh script created by InstallSoftware.sh
• The .mac is modified using sed on the worker node to modify paths to LAV matrix files, which are installed in the software area by InstallSoftware.sh
• The actual job script is attached (needs editing and streamlining)

Bulk job submission (job splitting)

1. Create N .mac files using the template
2. Create one Ganga script including the list of N .mac files
3. Run this script via Ganga

Problems encountered

• DPM does not work properly
