DescriptionGalactic cosmic rays are the high-energy particles that stream into our solar system
from distant corners of our Galaxy and some low energy particles are from the Sun which are associated with solar flares.
The Earth atmosphere serves as an ideal detector for the high energy cosmic rays which interact with the air molecule nuclei causing propagation of extensive air showers.
In recent years, there are growing interests in the applications of the cosmic ray
measurements which range from the space/earth weather monitoring, homeland
security based on the cosmic ray muon tomography, radiation effects on health via
air travel, etc.
A simulation program (based on the GEANT4 software package developed at CERN)
has been developed at Georgia State University for studying the cosmic ray showers
in atmosphere. The results of this simulation study will provide unprecedented
knowledge of the geo-position-dependent cosmic ray shower profiles and significantly
enhance the applicability of the cosmic ray applications. In the paper, we present the
computational challenges and the opportunities for carrying out the cosmic ray
shower simulations at the global scale using various computing resources including XSEDE.
