Description
Validation of hadronic physics processes of the Geant4 simulation
toolkit is a very important task to ensure adequate physics results for
the experiments being built at the Large Hadron Collider. We report on
simulation results obtained using the Geant4 Bertini cascade
double-differential production cross-sections for various target
materials and incident hadron kinetic energies between 0.1-10 GeV [1, 2].
The cross-section benchmark study in this work has been performed using
a Linux cluster set up with the Red Hat Linux based NPACI Rocks Cluster
Distribution. For analysis of the validation data we have used the
Parallel ROOT Facility (PROOF). PROOF has been designed for setting up a
parallel data analysis environment in an inhomogeneous computing
environment. Here we use a homogeneous Rocks cluster and automatic class
generation for PROOF event data-analysis [3].
