Job assignment apparatus, job assignment method, and network system

A job assignment apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and the processor configured to:
• determine whether a first job is allocated to at least one arithmetic devices among a plurality of arithmetic devices which connects to a switch,
• when the first job is not allocated to the at least one arithmetic devices, perform assignment of the first job to a first arithmetic device and a second arithmetic device among the plurality of arithmetic devices in such a way that data is transmitted in a first direction, the first job being processed in a process algorithm in which a plurality of arithmetic devices sequentially transmit data, the first arithmetic device being connected to the second arithmetic device via a first switch and a second switch, the first direction being a direction from the first switch to the second switch, and
• when the first job is allocated to the at least one arithmetic devices, perform assignment of a second job which is assigned after the first job to a third arithmetic device and a fourth arithmetic device among the plurality of arithmetic devices in such a way that data is transmitted in a second direction, the second job being processed in the process algorithm, the third arithmetic device being connected to the fourth arithmetic device via the first switch and the second switch, the second direction being a direction from the second switch to the first switch.
