N-DIMENSIONAL TORUS TYPE DISTRIBUTION PROCESSING SYSTEM, GROUP COMMUNICATION METHOD AND GROUP COMMUNICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce a transfer time and transfer frequency in an n-dimensional torus type distribution processing system.;SOLUTION: A plurality of processes arrayed in a two-dimensional direction successively transfer at least a portion of data carried by themselves to processes adjacent to a first direction, and make all processes lined up in a first direction carry preliminarily carried original data (S12 to S16), and successively transfers at least a portion of the data carried by themselves to processes adjacent to a second direction, and make all the processes lined up in the second direction carry at least a portion of the data carried by themselves after the previously performed data transfer processing (S18 to S22). Thus, generation of a transfer standby time due to data collision on a system can be prevented. In this case, even when n-dimensional (n2), the similar data transfer can be achieved by repeating the similar data transfer by (n-1) times while making the directions different from each other in addition to the two directions.;COPYRIGHT: (C)2010,JPO&INPIT
