Apparatus and method to configure an optimum number of circuits for executing tasks

A method for controlling an information processing device including a programmable circuit configured to configure circuits for executing tasks, the method comprising:

• estimating an execution time-period required for executing a first task by first circuits configured in the programmable circuit;
• determining a configuration number indicating a number of second circuits that are to be configured, in the programmable circuit, for executing a second task to be executed after the first task, based on the estimated execution time-period and a configuration time-period required for configuring the configuration number of the second circuits in the programmable circuit;
• causing the programmable circuit to configure, during execution of the first task, the configuration number of the second circuits;
• adjusting the number of second circuits that are to be configured, based on a relationship between a time at which the first task is completed and a time at which configuration of the second circuits in the programmable circuit is completed;
• determining a second configuration number indicating a number of the second circuits for which a total time period from a start time at which configuration of the second circuits in the programmable circuit is started to an end time at which execution of the second task by the second circuits is completed is reduced;
• and
• in a case where the first task is completed before configuration of the first configuration number of the second circuits in the programmable circuit is completed:
• causing the programmable circuit to stop configuration of a new circuit for the second circuits when a third configuration number indicating a number of the second circuits that are configured in the programmable circuit until completion of the first task is equal to or greater than the second configuration number, and
• causing the programmable circuit to configure the second configuration number of the second circuits in the programmable circuit when the third configuration number is smaller than the second configuration number.
