Allocating method, allocating apparatus, and computer product

An allocating apparatus comprising:

• a first transmitter that transmits to any one given apparatus among a plurality of apparatuses capable of executing an identical process and respectively having a different processing performance, a command for the process;
• a second transmitter that duplicates the command and transmits resulting duplicated commands to an apparatus group that is not executing the process and among the plurality of apparatuses;
• a measurer that measures for the given apparatus and each apparatus of the apparatus group, a utilization rate acquired when the command is executed;
• an identifier that based on the utilization rate for the given apparatus, identifies an apparatus to be switched among the apparatus group;
• and
• a switcher that switches a transmission destination of the command, from the given apparatus to the apparatus to be switched.

A computer-readable medium storing therein an allocating program that causes a computer to execute a process, the process comprising:

• transmitting to any one given apparatus among a plurality of apparatuses capable of executing an identical process and respectively having a different processing performance, a command for the process;
• duplicating the command and transmitting resulting duplicated commands to an apparatus group that is not executing the process and among the plurality of apparatuses;
• measuring for the given apparatus and each apparatus of the apparatus group, a utilization rate acquired when the command is executed;
• identifying based on the utilization rate for the given apparatus, an apparatus to be switched among the apparatus group;
• and
• switching a transmission destination of the command, from the given apparatus to the apparatus to be switched.
