Information processing device and resource allocation method

A resource allocation method executable by an information processing device that includes a plurality of arithmetic processing units provided with a plurality of arithmetic processing unit cores and that creates a plurality of virtual machines represented by setting information, the resource allocation method comprising:

• 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 stored by a storage which has stored therein setting information that specifies, for each virtual machine to be created, a number of arithmetic processing unit cores 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,
• referring to, by a virtual machine monitor, 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 are associated with a failure occurring in any of the arithmetic processing units provided with the arithmetic processing unit cores, wherein,
• the referring to includes
• assigning, by the virtual machine monitor, a priority to each of the number of arithmetic processing unit cores according to an allocation-priority determination policy that assigns a first priority to an arithmetic processing unit whose arithmetic processing unit cores have not been allocated any virtual machine, a second priority to an arithmetic processing unit whose arithmetic processing unit core has been allocated a virtual machine that belongs to a same group as the first virtual machine, and a third priority to an arithmetic processing unit whose arithmetic processing unit core has been allocated a virtual machine that does not belong to the same group as the first virtual machine, and
• allocating, by the virtual machine monitor, according to the rule and the allocation-priority determination policy, arithmetic processing units including the arithmetic processing unit cores to be allocated to the first virtual machine, in an order of priority of the first priority, the second priority, and the third priority, wherein the second priority is lower than the first priority and the third priority is lower than the second priority.

A non-transitory computer-readable recording medium having stored therein a program for causing an information processing device that includes a plurality of arithmetic processing units provided with a plurality of arithmetic processing unit cores and that creates a plurality of virtual machines represented by setting information to execute a process comprising:

• 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 stored by a storage which has stored therein setting information that specifies, for each virtual machine to be created, a number of arithmetic processing unit cores 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,
• referring 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, wherein
• the referring includes
• assigning, by a virtual machine monitor, a priority to each of the number of arithmetic processing unit cores according to an allocation-priority determination policy that assigns a first priority to an arithmetic processing unit whose arithmetic processing unit cores have not been allocated any virtual machine, a second priority to an arithmetic processing unit whose arithmetic processing unit core has been allocated a virtual machine that belongs to a same group as the first virtual machine, and a third priority to an arithmetic processing unit whose arithmetic processing unit core has been allocated a virtual machine that does not belong to the same group as the first virtual machine, and
• allocating, by the virtual machine monitor, according to the rule and the allocation-priority determination policy, arithmetic processing units including the arithmetic processing unit cores to be allocated to the first virtual machine, in an order of priority of the first priority, the second priority, and the third priority, wherein the second priority is lower than the first priority and the third priority is lower than the second priority.
