To localize accesses to input data for improving the performance by use of a cache memory at the time of performing simulation calculation of repeating random extraction of elements by use of random numbers from a set of input data on a computer having the cache memory.
The random number generation system 101 comprises a random number set generation part 102 generating random numbers; an access information recording part 115 acquiring access patterns to random numbers by parallel processing as a random number set storage table 109 and an access order storage table 111; and an alignment processing part 106 automatically aligning the random numbers in the random number set storage table 109 based on information acquired by the access information recording part 115. This system is connected to a simulation calculation system 114.
