How to control the application
DaVinci is controlled via jobOptions as any Gaudi
application. In the subdirectory options there is an
example joboptions file
options/DaVinci.opts
is to be modified and customized. It includes DaVinciCommon.opts that defines the services and DLLs to be loaded and are common to any job. Default options for algorithms and tools in the DaVinciTools & DaVinciSicb libraries are loaded automatically, but can be overwritten in DaVinci.opts later on.
To run the L0 trigger simulation uncomment the corresponding line in DaVinci.opts
Options for the example selection routines are provided in separate files included in DaVinci.opts
Comments in DaVinci.opts are provided to give an indication of how to modify the options.
An example of a script of how to run a job (both interactively and in batch) is provided in the subdirectory job
job/DaVinci.job
You must provide as argument the dbase version corresponding to the files you want to process.
Three possibility are given to provide the jobOptions to a DaVinci application and are taken in the following order of priority:
lxplus> DaVinci.exe myDaVinci.opts
> setenv JOBOPTPATH myDaVinci.opts
$DAVINCIROOT/options/DaVinci.opts
