INTENSIVE OPERATION EXECUTING METHOD, AND COMPUTER SYSTEM THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method for executing plural intensive operations in parallel at a high speed. SOLUTION: In the computer system where plural processors connected by a network can use self-memory areas and the self-parts of a data base containing data which can be divided into one or plural groups, (a) a space for storing M(integer of not more than N)-pieces of operation results in N-pieces of intensive operations is secured in the self-memory area (210). (b) M-pieces of intensive operations are collected and they are executed for the self-part of the data base (220). (c) The operation results in the respective processors of M-pieces of intensive operations are transmitted to the processor which is to integrate them and the processor which is to integrate them calculates a final result (230). (d) Steps (a)-(c) are repeated until N-pieces of intensive operations terminate (240).
