Abstract
Virial coefficients for various molecular models are calculated up to B 8 using the Mayer Sampling Monte Carlo method and implemented on a graphics processing unit (GPU). The execution time and performance of these calculations is compared with equivalent computations done on a CPU. The speedup between virial coefficient computations on a CPU (w/optimized C code) and a GPU (w/CUDA) is roughly two orders of magnitude. We report values of B 6, B 7, and B 8 of the Lennard-Jones (LJ) model, as computed on the GPU, for temperatures T = 0.6 to 40 (in LJ units).
