Program conversion device and method, process switching method, method of determining execution scheme and program storage medium therefor, processor system, and parallel execution scheme

摘要

Provided is to a program conversion device which can use processor resources of a system to the utmost and enhance performance ability. The program conversion device includes: specific process determining unit which determines a range of a partial program to perform a specific process in a target program which includes a first execution scheme specifying program which can be executed in parallel with a first ratio of being a usage ratio of a first usage quantity with respect to a first resource of a first processor and a second usage quantity with respect to a second resource of a second processor; and process converting unit which converts the partial program into a second execution scheme specifying program which can be executed in parallel with a second ratio of being the usage ratio different from the first ratio.

1. A program conversion device, comprising:
a memory; a processor; storing a specific process determining unit in the memory which determines a range of a partial program to perform a specific process in a target program which includes a first execution scheme specifying program which executes in parallel with a first ratio of being a usage ratio of a first usage quantity with respect to a first resource of a first processor and a second usage quantity with respect to a second resource of a second processor; and storing a process converting unit in the memory which converts the partial program into a second execution scheme specifying program by the processor in which the first processor and the second processor operate simultaneously with a second ratio of being the usage ratio different from the first ratio and generating a converted program, wherein the converted program includes a process switching program which switches from the first execution scheme specifying program to the second execution scheme specifying program and vice versa based on a command from outside.
