Computer-readable recording medium storing control program, system, and control method

A system comprising:

• a resource pool;
• and
• an information processing device that executes an application that performs iterative processing, wherein
• the information processing device includes
• a prediction unit that predicts, based on completion time of a certain number of times of iteration obtained from the application and a total number of times of iteration, predicted completion time for a case where the iterative processing is executed as many times as the total number of times of iteration,
• a comparison unit that compares the predicted completion time with a time limit specified by a user,
• a performing unit that, based on a comparison result, causes the application to output a checkpoint, and after execution of the application is stopped, performs a configuration change of resources for the information processing device by using the resource pool, and
• a resumption unit that restarts the application in the information processing device and resumes execution from the output checkpoint.

A control method for causing a computer to execute a process comprising,

• in execution of an application in a system that includes a resource pool:
• predicting, based on completion time of a certain number of times of iteration obtained from the application that executes iterative processing and a total number of times of iteration, predicted completion time for a case where the iterative processing is executed as many times as the total number of times of iteration;
• comparing the predicted completion time with a time limit specified by a user;
• based on a comparison result, causing the application to output a checkpoint, and after execution of the application is stopped, performing a configuration change of resources for an information processing device that is used for execution of the application by using the resource pool;
• and
• restarting the application in the information processing device for which the configuration change has been performed, and resuming execution from the output checkpoint.
