We present a massively parallel application for sampling secondary particles in high energy physics (HEP) simulation on a Graphics Processing Unit (GPU). HEP experiments primarily uses the Geant4 toolkit (Geant4) to simulate the passage of particles through a general-purpose detector, which requires intensive computing resources due to the complexity of the geometry as well as
physics...

GooFit is a thread-parallel, GPU-friendly function evaluation library, nominally designed for use with the maximum likelihood fitting program MINUIT. In this use case, it provides highly parallel calculations of normalization integrals and log (likelihood) sums. A key feature of the design is its use of the Thrust library to manage all parallel kernel launches. This allows GooFit to execute on...

The search for matter-antimatter asymmetries requires highest precision analyses and thus very large datasets and intensive computing. This contribution discusses two complementary approaches where GPU systems have been successfully exploited in this area. Both approaches make use of the CUDA Thrust library.
The first approach is a generic search for local asymmetries in phase-space...

The Pierre Auger Observatory is the currently largest experiment dedicated to unveil the nature and origin of the highest energetic cosmic rays. The software framework 'Offline' has been developed by the Pierre Auger Collaboration for joint analysis of data from different independent detector systems used in one observatory. While reconstruction modules are specific to the Pierre Auger...
