<p>A parallel processor apparatus, which enables a blocking work for assuring a bucket write/read performance with a storage quantity in an ordinary range so as to largely improve the bucket write/read performance, has a first dividing unit (5) for dividing data that is an object of a process into plural sets of bucket groups each of which is a set of tuples of plural sorts when the data is transmitted from a first processor group (2) to an intermediate processor group (4) to temporarily store the data in the intermediate processor group (4). The parallel processor apparatus further includes a second dividing unit (6) for reading each of the plural sets of bucket groups to divide it into buckets each of which is a set of tuples of the same sort when the data is transmitted from the intermediate processor group (4) to a second processor group (3), and storing the data in the second processor group (3). The parallel processor apparatus is applicable to a parallel computer system having plural processors concurrently operating in parallel to execute a predetermined task. <IMAGE></p> |
