Abstract
An information processing apparatus includes a memory and a processor coupled to the memory. The processor is configured to monitor each of loads of processor cores performing processes for which a parallel operation is inhibited. The processor cores are included in the information processing apparatus. The processor is configured to identify a first process that is being performed by a first processor core having a load that equals or exceeds a predetermined threshold value of a first load from among the processor cores based on a correspondence relationship between the processes and the first processor core.
Claims7
An information processing apparatus, comprising:
- a memory stores relation information indicating correspondence relationships between processes and processor cores;
- and
- a processor coupled to the memory, the processor configured to:
- monitor each of loads of the processor cores performing the processes for which a parallel operation is inhibited, the processor cores being included in the information processing apparatus;
- identify a first process that is being performed by a first processor core having a load that equals or exceeds a predetermined threshold value of a first load from among the processor cores based on a correspondence relationship between the processes and the first processor core;
- determine, upon the first process being started up by the first processor core, whether the first process is a non-parallel process based on information indicative of a non-parallel process, the non-parallel process being a process for which a parallel operation is inhibited;
- identify, upon determining that the first process is a non-parallel process, the first process based on the relation information stored in the memory;
- determine whether the load of the first processor core equals or exceeds a predetermined threshold value of a second load;
- and
- allocate, upon determining that the load of the first processor core equals or exceeds the predetermined threshold value of the second load, the first process to a second processor core of the processor cores, the second processor core being different from the first processor core;
- and
- update the relation information stored in the memory, based on a correspondence relationship between the first process and the second processor core.
