PROBLEM TO BE SOLVED: To provide a parallel simulation device which does not require estimation of the number of random numbers necessary for execution of one trial prior to execution of any trial to ensure repeatability of the trial or exclusive access for generation of random numbers.SOLUTION: A parallel random number generation part 3 determines an update frequency of a state variable in an initial generation of random numbers on the basis of different identification values each of which is given for parallel trial execution parts 2-1 to 2-n by using a seed value common to the parallel trial execution parts 2-1 to 2-n, and an update frequency of a state variable in generation of random numbers after the initial time on the basis of a parallel number which is the number of the parallel trial execution parts 2-1 to 2-n. A trial execution part 4 executes a trial by using the random numbers generated by the parallel random number generation part 3.SELECTED DRAWING: Figure 1 |
