The goal of this project is to simulate the energy spectrum observed with a scintillator (http://en.wikipedia.org/wiki/Scintillator) placed next to a point gamma source (http://en.wikipedia.org/wiki/Gamma_ray) by Monte Carlo simulation (By following the path and interactions of a large number of individual photons). The GPU enables the simulator to run on average 10x faster than on a CPU.
The project builds upon the nVidia CUDA API.
The simulation consists of a point gamma source and a box shaped scintillator. Most physical properties, like positioning, cross sections,
as well as simulation parameters are configurable via command line or the input-data.txt configuration file.
The simulation then runs on the GPU (and optionally on CPU with fewer number of photons, to be able to verify the GPU results).
The three source files include the scintillator.cu which defines the main entry point, and scintillator_gold.cpp which runs the simulation
on CPU, and scintillator_kernel.cu which runs the simulation on GPU.
You can either build the source with the included Makefile or import the project in Visual Studio with the included sln project file.
This was actually my thesis, and you can find the (unfortunately only hungarian) paper under docs.
