This analysis compares performance metrics of GPU-accelerated photon propagation in optical TPC, suggesting significant speed improvements over CPU-only simulation.
We investigate the performance of , a 7.5 GPU-accelerated photon propagation tool compared with a single-threaded simulation. We compare the simulations using an improved model of the gaseous time projection chamber. Performance results suggest that improves simulation speeds by between 58.47± 0.02 58.47 ± 0.02 and 181.39± 0.28 181.39 ± 0.28 times relative to a CPU-only simulation and these results vary between different types of GPU and CPU. A detailed comparison shows that the number of detected photons, along with their times and wavelengths, are in good agreement between and .
