Mapping calculation units by dividing a calculation model which can be calculated in parallel on an application program

摘要

This invention aims to perform mapping in a user space without concern for an architecture of a parallel computer and to obtain a high- speed mapping pattern. An N-dimensional model is divided by a user into a plurality of calculation units. The calculation units and physical processors are assigned with an identification code. Correspondence therebetween is held on an address conversion table. By accessing the address conversion table, the user can freely perform a mapping operation. Thereafter, interprocessor communication is carried out by the use of the identification code assigned to the calculation units.
