SPEC CPU2000 Benchmark Description File
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.
Programming Language
Fortran 77
Known portability issues
None
