Overview<\/span><\/h2>\n

Geant 4 is a toolkit for the simulation of the passage of particles through matter developed at CERN<\/a>. Its areas of application include high energy, nuclear and accelerator physics, as well as studies in medical and space science.<\/p>\n

Restrictions on use\/License information<\/h2>\n

Geant 4 is free software<\/em> as defined by the terms of the Geant4 software license<\/a>.<\/p>\n

There is no restriction on the number of simultaneously running programs on HTCondor.<\/p>\n

You can see which nodes have which GEANT4 versions available via:<\/p>\n

\r\nsubmitter ~]$ condor_status -long | grep GEANT\r\n<\/pre>\n

Set up procedure on submit node<\/span><\/h2>\n
To access the software you must first run the commands:<\/p>\n
module load gcc\/6.4.0\r\nmodule load geant4\/<Geant4 version>\r\n<\/pre>\n
Running the application<\/span><\/h2>\n
In order to run Geant4 jobs on HTCondor, it is first necessary to compile the Geant4 code on the HTCondor submit node. This is because the version of Geant4 deployed has been compiled using version 6.4.0 of the GNU Compiler suite.<\/p>\n
Step 1 \u2013 Compiling your Geant4 code<\/strong><\/p>\n
Geant4 requires its executable codes be built in a separate folder from the program source code. Assuming that the source code is in <source folder><\/tt> then from a linux terminal prompt, run the following commands from inside your <build folder><\/tt>:<\/p>\n
cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ <source folder>\r\nmake\r\n<\/pre>\n
