Method and related device for determining shared virtual memory page management mode

Abstract

The embodiment of the invention discloses a method and related equipment for determining the management mode of shared virtual memory pages. Wherein, a method for determining the management mode of the shared virtual memory page may include: monitoring the access characteristics of the process to the shared virtual memory page; if the monitored access characteristics meet the first setting condition, and the current management mode of the shared virtual memory page For the distributed shared memory mode, change the management mode of the shared virtual memory page to the shared physical memory mode. The technical solution provided by the embodiment of the present invention is beneficial to improving the access performance of the shared virtual memory.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and related equipment for determining a shared virtual memory page management mode. Background technique [0002] Moore's Law, proposed by Gordon Moore, one of the founders of Intel, has been guiding the development of the semiconductor industry and the speed of information technology progress for nearly half a century. Judging from the information disclosed by Intel, Moore's Law will continue to be effective in the next 10 years, and it is expected that more than 1.024×10 chips will be integrated on a single chip in 2022. 12 transistors. [0003] However, the current era of improving computing performance solely by increasing the main frequency has passed, and the performance growth of the central processing unit (CPU, Central Processing Unit) has encountered the limitations of physical laws such as power consumption, interconnection delay, and design complexity. . ...

Problems solved by technology

In the process of research and practice, the inventors found that in some application scenarios, the access performance of shared virtual memory pages fixedly adopting DSM mode as its management mode cannot well meet the actual needs, while in other application scenarios, The access performance of the shared virtual memory page that uses the SPM mode as its management mode cannot meet the actual needs very well.
