+description: |
+  [SixTrack](http://cern.ch/sixtrack) is a software for simulating and analysing
+  the trajectory of high energy particles in accelerators. It has been used in
+  the design and optimization of the LHC and is now being used to design the
+  High-Luminosity LHC (HL-LHC) upgrade that will be installed in the next decade.
+  Sixtrack has been adapted to take advantage of large scale volunteer computing
+  resources provided by the
+  [LHC@Home](http://lhcathome.web.cern.ch) project.
+  It has been engineered to give the exact same results after millions of
+  operations on several, very different computer platforms. The source code is
+  written in Fortran, and is pre-processed by two programs that assemble the code
+  blocks and provide automatic differentiation of the equation of motions. The
+  code relies on the `crlibm` library,
+  careful arrangement of parenthesis, dedicated input/output and selected
+  compilation flags for the most common compilers to provide identical results on
+  different platforms and operating systems. An option enables the use of the
+  Boinc library for volunteer
+  computing. A running environment SixDesk is used to generate input files, split
+  simulations for LHC@Home (link sends e-mail) or CERN cluster and collect the
+  results for the user. SixTrack is licensed under LGPLv2.1.

+title: Hardware acceleration of scattering routines in SixTrack
+layout: gsoc_proposal
+project: SixTrack
+year: 2019
+organization: CERN
+---
+
+## Project Description
+
+When high energy protons in the LHC are intercepted by the collimator jaws, they undergo scattering due to the interactions of the incoming protons with either the electromagnetic field of the atoms, or the strong potential of the nucleus. Presently, a physics model for the scattering mechanisms is implemented in SixTrack using a Monte-Carlo code. The interactions fall into four categories: nuclear interaction, coulomb scattering, ionization and hard electromagnetic processes (e.g. pair production).
+
+A strong background in computer science and programming languages as well the
+interest to understand computational physics methods implemented in the code are
+sought. The unique challenge will be offered to work with a high-performance
+production code that is used for the highest energy accelerator in the world -
+and thus the code's reliability and backward compatibility cannot be
+compromised. There will be the opportunity to learn about methods used in
+simulating the motion of particles in accelerators.
+
+
+
+## Expected results
+Demonstrate that the C code running on a GPU can run the scattering routines at the same speed or faster than on CPU, while keeping bit-level identical results.
