INFORMATION PROCESSING DEVICE AND RESOURCE ALLOCATION METHOD

摘要

A device includes a storage which has stored therein setting information that specifies, for each virtual machine to be created, the number of arithmetic processing unit cores that have to be allocated to a virtual machine, and group information that represents a plurality of virtual machines operating in cooperation as a group, from among the virtual machines represented by the setting information, and a virtual machine monitor, when a first virtual machine has been created, from among the virtual machines represented by the setting information, which refers to the setting information and the group information so as to allocate as many arithmetic processing unit cores as the setting information specifies to the first virtual machine, according to a rule that takes account of a decrease in operation performance of all the operable virtual machines that is associated with a failure occurring in any of the arithmetic processing units.

1. An information processing device comprising:
a storage which has stored therein setting information that specifies, for each virtual machine to be created, the number of arithmetic processing unit cores that have to be allocated to a virtual machine, and group information that represents a plurality of virtual machines operating in cooperation as a group, from among the virtual machines represented by the setting information; and a virtual machine monitor, when a first virtual machine to which the arithmetic processing unit cores are to be allocated has been created, from among the virtual machines represented by the setting information, which refers to the setting information and the group information so as to allocate as many arithmetic processing unit cores as the setting information specifies to the first virtual machine, according to a rule that takes account of a decrease in operation performance of all the operable virtual machines that is associated with a failure occurring in any of the arithmetic processing units provided with the arithmetic processing unit cores.
