Abstract

An image forming apparatus includes a hardware processor including CPUs each including cores, a process being executed by the CPUs, wherein the hardware processor managing the cores causes a first process or a second process to be executed, when the first process is executed, while electric power is uniformly supplied to the cores, allocates a pre-process in which sequential processing is performed to a part of the cores and a post-process in which parallel processing is performed to another part of cores, and when the second process is executed, for a part of the CPUs, allocates the pre-process to a part of the cores while electric power is supplied thereto and causes electric power supply to another part of cores to be stopped, and for another part of the CPUs, allocates the post-process to at least a part of the cores while electric power is uniformly supplied to the cores.

Dependent claims

An image forming apparatus comprising a hardware processor including a plurality of central processing units (CPUs) each including a plurality of cores, a process being executed by the CPUs, wherein

the hardware processor that manages the plurality of cores
causes either one of a first process or a second process to be executed,
when causing the first process to be executed, while causing electric power to be uniformly supplied to the plurality of cores included in each of the CPUs, allocates a pre-process in which sequential processing is performed to a part of cores among the plurality of cores and allocates a post-process in which parallel processing is performed to another part of cores, and
when causing the second process to be executed, among the plurality of CPUs,
for a part of the CPUs, allocates the pre-process to a part of cores among the plurality of cores while causing electric power to be supplied to the part of cores and causes supply of electric power to another part of cores to be stopped, and
for another part of the CPUs, allocates the post-process to at least a part of the plurality of cores while causing electric power to be uniformly supplied to the plurality of cores.
