Abstract

The embodiments of the present application disclose a memory allocation method, device, storage medium, and electronic device, wherein the embodiments of the present application count the number of historical requests for memory allocation requests received in the past preset time period at each preset time period, and determine the historical memory request amount corresponding to each historical memory allocation request; determine the expected memory request amount and the expected number of requests according to the number of historical requests and the historical memory request amount corresponding to each historical memory allocation request; perform memory fragmentation Arrange to obtain a continuous memory space whose memory amount is not less than the expected memory request amount, wherein the number of the continuous memory space matches the expected number of requests; when a memory allocation request is received, based on the continuous memory Space for memory allocation, which improves the performance overhead caused by memory fragmentation and improves the efficiency of memory allocation.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a memory allocation method, apparatus, storage medium, and electronic device. Background technique [0002] During the memory allocation process of the Linux kernel, if the system memory does not meet the requirements, it will wake up the memory reclamation thread and try to reclaim a certain number of page frames. The memory reclamation thread wakes up another defragmentation thread and specifies the required amount of memory while waking up the thread. In the execution of the resize operation, this thread will continue to scan the entire memory domain until enough page frames are obtained to piece together a high-level memory block that meets the required amount of memory. However, during the running process of the system and the application, there are often multiple consecutive memory allocation requests. This allocation scheme is difficult to meet the...
