Abstract: Geant4 is an open-source toolkit library for Monte Carlo particle transport simulations at high energies (from few eV), developed by CERN and maintained by a large, international collaboration. Thanks to...
We ported on the GPU with CUDA the Gaia Astrometric Verification Unit-Global Sphere Reconstruction (AVU-GSR) Parallel Solver. The code aims to find the astrometric parameters of ~10^8 stars, the attitude and the instrumental settings of the Gaia satellite, and the global parameter 𝛾 of the PPN formalism, by solving a system of linear equations, 𝐀 × 𝒙=𝒃, with the LSQR iterative algorithm. The...
