PURPOSE: To enable blocking for guaranteeing the bucket write/read performance of a memory capacitance with an ordinary range and to drastically improve the bucket write/read performance in a parallel processor system such as a parallel computer system for executing a prescribed job by parallelly operating plural processors at the same time. CONSTITUTION: When transmitting data from a first processor group 2 to an intermediate processor group 4, a first dividing means 5 divides the data of a processing object into plural pairs of bucket groups as the assembly of respective plural classes of tuples and temporarily stores them in the intermediate processor group 4, and when transmitting data from the intermediate processor group 4 to a second processor group 3, a second dividing means 6 reads the plural pairs of bucket groups for each bucket group, divides them into buckets as the assembly of only the same class of tuples and stores them in the second processor group 3. |
