| Outline of Final Research Achievements |
We investigated properties of the realized volatility calculated with various sampling times. The hybrid Monte Carlo algorithm that infers the realized stochastic volatility model was developed. Since the hybrid Monte Carlo algorithm can be parallelized we made a program that executes the GPU calculation. We find that the GPU calculation is faster than the CPU calculation on a personal computer. We also use the OpenACC that enables us to make a GPU program easily, and find that the computational speed of the OpenACC is comparable with that of the CUDA.
