MANY-BODY PROBLEM COMPUTING SYSTEM

摘要

PPROBLEM TO BE SOLVED: To compress an overhead of an external bus access for shortening a computing required time and hence for an improvement in usage performance of CPU time resources in a system connecting a many-body problem operation computer 2 to a host computer 1 via an external bus 3. PSOLUTION: The operation computer 2 for computing interaction force between particles based on particle data about multiple particles given by the host computer 1 for offering a computing result to the host computer 1 via the external bus 3 has a control procedure function for computing particle interaction force between particles while aiming at the all particles as target particles by changing the target particles sequentially in the particle data, and consequently, and computing on all the particles can be carried out autonomously. In this way, setting of the target particle can be carried out autonomously by means of the operation computer 2 without repeating setting of the target particle based on random access by the host computer 1, and the overhead is compressed for reduction in a computing required time.
