BDSIM¶
Hostgroups
These features are available for the following hostgroups and their respective subhostgroups:
-
BDSIM in batch mode:
machine_protection/linux
-
BDSIM with the Qt visualizzer:
machine_protection/linux/ts
The prefered way to run BDSIM is to use the CVMFS builds that have been prepared and are compatible with CC7 and C8. The toolchain (compiler and libraries) is re-used from CVMFS as well. Batch and interactive modes are supported.
tl;dr¶
Source BDSIM for use in batch mode
source /cvmfs/beam-physics.cern.ch/bdsim/x86_64-centos7-gcc9-opt/bdsim-env-v1.6.0-g4v10.7.2.3.sh
Using BDSIM in interactive mode with the Qt visualizer
The sourced environment includes Qt5 by default and BDSIM can be used as is with the visualizer.
Some additional details to use BDSIM from CVMFS¶
The repository 'beam-physics.cern.ch' holds a 'bdsim' sub-repository which are available from any machine with access to CVMFS:
[chernals@mp-linux-ts-01 ~]$ ls /cvmfs/beam-physics.cern.ch/

[chernals@mp-linux-ts-01 ~]$ ls /cvmfs/beam-physics.cern.ch/bdsim

To use one of the builds, simply source the environment file. For example, to use BDSIM v1.5.1 with Geant4 v10.7.1.1; BDSIM and the associated tools will then be available in your path:
[chernals@mp-linux-ts-01 ~]$ source /cvmfs/beam-physics.cern.ch/bdsim/x86_64-centos7-gcc8-opt-lcg100/bdsim-env-v1.5.1-g4v10.7.1.1.sh
[chernals@mp-linux-ts-01 ~]$ which bdsim
/cvmfs/beam-physics.cern.ch/bdsim/x86_64-centos7-gcc8-opt-lcg100/bdsim-v1.5.1-g4v10.7.1.1/bin/bdsim
[chernals@mp-linux-ts-01 ~]$ which rebdsim
/cvmfs/beam-physics.cern.ch/bdsim/x86_64-centos7-gcc8-opt-lcg100/bdsim-v1.5.1-g4v10.7.1.1/bin/rebdsim
Using the BDSIM Python toolchain¶
The BDSIM Python toolchain (using Python 3.8 and ipython) is available via CVMFS as well and is automatically added to the $PYTHONPATH environment
variable when sourcing the above scripts:
[chernals@mp-linux-ts-01 ~]$ ll /cvmfs/beam-physics.cern.ch/bdsim/x86_64-centos7-gcc8-opt-lcg100/python-utils/
