  • Parallelization of random number generation processing by employing GPU
    Patent number: 8786617
    Abstract: A method of carrying out random number generation processing uses a GPU including a plurality of blocks each including at least one core, the random number generation processing including update processing of updating state vectors and conversion processing of converting the updated state vectors into random numbers having another distribution. The method includes carrying out, by one of the plurality of blocks, the update processing (S3), and carrying out, by the plurality of blocks, the conversion processing in parallel based on results of the update processing (S9). Therefore, it is possible to more efficiently generate a random number sequence which is the same as the one obtained through random number generation processing performed in a serial manner, by parallelizing a single random number generator in a GPU.
