Abstract

Disclosed are a method and a relevant device for determining a mode of managing a shared virtual memory page. The method for determining a mode of managing a shared virtual memory page comprises: monitoring an access characteristic of a process to the shared virtual memory page; and if the monitored access characteristic conforms to the first set condition and a current mode of managing the shared virtual memory page is a distributed shared memory mode, modifying the mode of managing the shared virtual memory page to a shared physical memory mode. The technical solutions provided by the embodiments of the present invention facilitate the improvement of 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 individual 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 comp...
