Abstract: The present invention provides a scheduling system, etc., capable of more efficiently enabling the processing performance possessed by a resource to be exhibited. This scheduling system has a scheduler for reserving a second communication channel as a second communication resource in accordance with a fifth instruction for reserving the second communication channel from a first communication channel, the second communication channel being capable of transmitting/receiving first data between a memory and an accelerator memory, the first data being processed by a task, and the fifth instruction being included in tasks processed by a calculation processing device having such resources as a many-core accelerator, the accelerator memory, a processor, a memory, and the first communication channel, the first communication channel being capable of transmitting/receiving data between the many-core accelerator and the processor.

Abstract: 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.
