Benchmark Name: SIXTRACK Benchmark Author: Frank Schmidt Benchmark Program General Category: High Energy Nuclear Physics Accelerator Design Benchmark Description: The function of the program is to track a variable number of particles for a variable number of turns round a model of a particle accelerator such as the Large Hadron Collider (LHC) to check the Dynamic Aperture (DA) i.e. the long term stability of the beam. Input Description: The input data defines the number of particles (60) to be tracked, the LHC accelerator components and geometry, the initial conditions of the accelerator and particles , and the number of turns to be tracked (variable according to required workload, test, train or ref). Output Description: The output starts with a report of the input data describing the accelerator components and topology. The initial conditions and tracking parameters follow. Next come the results of the pre-processing including the closed orbit and a check on the symplectic condition. The initial and final co-ordinates of each particle are then reported, with a possible intermediate report every 50,000 turns. A binary file is written, one per particle, reporting the initial, intermediate, and final co-ordinates.
