Title: Multi-threaded Geant4 on the Xeon-Phi with complex high-energy physics geometry

Abstract

To study the performance of multi-threaded Geant4 for high-energy physics experiments, an application has been developed which generalizes and extends previous work. Here, a highly-complex detector geometry is used for benchmarking on an Intel Xeon Phi coprocessor. Additonally, an implementation of parallel I/O based on Intel SCIF and ROOT technologies is incorporated and studied.

The total number of events processed is chosen as 100 times the number of threads. Nearly perfect scaling is observed up to the number of physics cores onmore » the chip (60, represented by the dashed vertical line), with increasing rate up to the maximum 4 threads per core.« less
