Hadronic Energy Resolution of a Combined High Granularity Scintillator Calorimeter System
/ CALICE Collaboration
This paper presents results obtained with the combined CALICE Scintillator Electromagnetic Calorimeter, Analogue Hadronic Calorimeter and Tail Catcher & Muon Tracker, three high granularity scintillator-SiPM calorimeter prototypes. The response of the system to pions with momenta between 4 GeV/c and 32 GeV/c is analysed, including the energy response, resolution, and longitudinal shower profiles. [...]

Stochastic optimization of GeantV code by use of genetic algorithms
/ Amadio, G (Sao Paulo State U.) ; Apostolakis, J (CERN) ; Bandieramonte, M (CERN) ; Behera, S P (Bhabha Atomic Res. Ctr.) ; Brun, R (CERN) ; Canal, P (Fermilab) ; Carminati, F (CERN) ; Cosmo, G (CERN) ; Duhem, L (Intel, Santa Clara) ; Elvira, D (Fermilab) et al.
GeantV is a complex system based on the interaction of different modules needed for detector simulation, which include transport of particles in fields, physics models simulating their interactions with matter and a geometrical modeler library for describing the detector and locating the particles and computing the path length to the current volume boundary. The GeantV project is recasting the classical simulation approach to get maximum benefit from SIMD/MIMD computational architectures and highly massive parallel systems. [...]

An intensive R&D; and programming effort is required to accomplish new challenges posed by future experimental high-energy particle physics (HEP) programs. The GeantV project aims to narrow the gap between the performance of the existing HEP detector simulation software and the ideal performance achievable, exploiting latest advances in computing technology.

Performance of GeantV EM Physics Models
/ Amadio, G (Sao Paulo State U.) ; Ananya, A (CERN) ; Apostolakis, J (CERN) ; Aurora, A (CERN) ; Bandieramonte, M (CERN) ; Bhattacharyya, A (Bhabha Atomic Res. Ctr.) ; Bianchini, C (Sao Paulo State U. ; Mackenzie Presbiteriana U.) ; Brun, R (CERN) ; Canal P (Fermilab) ; Carminati, F (CERN) et al.
The recent progress in parallel hardware architectures with deeper vector pipelines or many-cores technologies brings opportunities for HEP experiments to take advantage of SIMD and SIMT computing models. Launched in 2013, the GeantV project studies performance gains in propagating multiple particles in parallel, improving instruction throughput and data locality in HEP event simulation on modern parallel hardware architecture.
