Network system, information processing apparatus, and computer product

A computer readable storage medium comprising code that, when executed, causes a computer, in a network system including a data transfer device that transfers data and a plurality of information processing apparatuses connected to the data transfer device, to implement:

• a master information processing apparatus being one of the information processing apparatuses including
• a controlling unit that controls an order and a timing in and at which the information processing apparatuses including the master information processing apparatus transmit data to each of the information processing apparatuses, and
• a transmitting unit that transmits the data to each of the information processing apparatuses in the order and at the timing controlled by the controlling unit;
• and
• a slave information processing apparatus other than the master information processing apparatus including a transmitting unit that transmits the data to each of the information processing apparatuses in the order and at the timing controlled by the controlling unit.

An information processing apparatus connected to another information processing apparatus through a network, the information processing apparatus comprising:

• a storage unit that stores therein a table of a list of information processing apparatuses as data transmitters and a list of information processing apparatuses as transmission destinations of data, in which the data transmitters are associated with the transmission destinations, respectively, the table being received from the other information processing apparatus;
• a receiving unit that receives a data transfer instruction from the other information processing apparatus;
• a controlling unit that refers to the table according to the data transfer instruction, and identifies an information processing apparatus associated as a transmission destination with the information processing apparatus in the table;
• and
• a transmitting unit that transfers data to the information processing apparatus identified as the transmission destination by the controlling unit.
