<P>PROBLEM TO BE SOLVED: To improve the rate of the computing speed improvement of parallelization processing by eliminating restriction that it is necessary for the number M of computers in particle behavior analysis to which a force division method is applied to fulfill the relation of N^2. <P>SOLUTION: When the number M of available processors fulfills the relation of N(N+1)+1≤M≤(N+1)^2-1 (S212-YES), the force matrix of vertical (N+1) and horizontal (N+1) is used (S216). As for (N+1)^2-M of dummy processor parts in the force matrix of extended vertical (N+1) and horizontal (N+1), the information of particles is distributed so that a substantial process existing in the (N+1) th line is in charge as an alternative processor (S220). The speed improvement rate of the computing speed is made higher in carrying out parallel processing by the (N+1)^2 of computers than that in carrying out parallel processing by the N^2 of computers. <P>COPYRIGHT: (C)2008,JPO&INPIT |
