Heterogeneous many-core chip oriented quantized power consumption control method

Abstract

The invention discloses a heterogeneous many-core chip oriented quantized power consumption control method. The method comprises: obtaining reference power consumption data of a heterogeneous many-core chip in each state and establishing an external basic power consumption data table; obtaining a frequency grade table of all stable running frequencies supported by the heterogeneous many-core chip; and for all the stable running frequencies, establishing an existence relationship of chip power consumption of running same application codes in different frequencies, wherein the higher the frequency is and the higher the power consumption is, and the working power consumption of the lowest frequency grade is certainly smaller than the maximum stable running power consumption; establishing a power consumption management policy of the chip as a power consumption management basis; after a many-core operating system is started, initializing both a power consumption threshold register and a power consumption pre-warning register according to the maximum stable running power consumption; and when the operating system of the many-core chip runs, starting a power consumption management process by an external power consumption management system, and notifying the basic power consumption table, the frequency grade table and the power consumption management policy to the operating system of each heterogeneous many-core chip.

Description

technical field [0001] The invention relates to the field of computers, in particular to a quantized power consumption control method for heterogeneous many-core chips. Background technique [0002] The most prominent advantage of heterogeneous many-core processors is high performance, which is especially suitable for high-performance computing and is mainly used in large-scale practical systems such as ultra-large-scale parallel computers. At the same time, it also has the characteristics of high peak power consumption and large differences in power consumption in different working modes and operating states. [0003] Although the power consumption of a single slave core in a heterogeneous many-core chip is very low, its large number is the main body of the chip power consumption; the large number of slave cores in the chip accounts for most of the power consumption of the chip, which is the key to power management. main object. [0004] The operating status of the chip i...
