SUMMARY:Charged Particle Reconstruction Using SYCL with the Traccc Project
DESCRIPTION:Minisymposium\n\nAttila Krasznahorkay and Andreas Salzburger (
 CERN); Beomki Yeo (Lawrence Berkeley National Laboratory); Stephen Nichola
 s Swatman (University of Amsterdam, CERN); Joana Niermann (University of G
 öttingen); and Guilherme Metelo Rita De Almeida (University of Lisbon, CER
 N)\n\nReconstructing the tracks left by high energy, electrically charged 
 particles in specialised particle detectors is one of the most challenging
  software tasks in modern High Energy Physics. In recent years several pro
 jects took it on themselves to find and implement track reconstruction alg
 orithms suitable for hardware accelerators. In many cases this lead to alg
 orithmic compromises, using simplified descriptions of the detector geomet
 ry, input data and magnetic field. The traccc project was started as an R&
 D initiative of the ACTS common track reconstruction project. It aims to d
 emonstrate the feasibility of a complete track reconstruction algorithm ch
 ain on both traditional CPU, and GPGPU hardware architectures. A large emp
 hasis in the development is put on sharing as much code between the CPU an
 d GPGPU implementations as possible, and avoiding algorithmic and physics 
 performance compromises. In this talk I will present the state of the art 
 of this R&D project. I will describe its components dedicated to handling 
 well defined sub-tasks in the track reconstruction, and I will present per
 formance results with the code. As run on a variety of hardware, with the 
 help of the SYCL programming language.\n\nDomain: Computer Science, Machin
