Method for managing memory pools

Abstract

The invention discloses a method for managing memory pools. The method comprises the step of controlling the first memory pool to provide a dynamic memory allocation operation and a memory release operation, and controlling the second memory pool not to provide a dynamic memory allocation operation or a memory release operation; when the number of memories allocated in the first memory pool is greater than a first threshold value and the number of memories used in the first memory pool is smaller than a second threshold value, controlling the first memory pool only to provide the memory release operation, and controlling the second memory pool to provide the dynamic memory allocation operation and the memory release operation; after the memories in the first memory pool are all released, clearing the first memory pool, controlling the second memory pool to provide the dynamic memory allocation operation and the memory release operation, and controlling the first memory pool not to provide the dynamic memory allocation operation or the memory release operation. The method for managing the memory pools solves the technical problem that in the prior art, since chunk addresses of memory pools are not continuous and entire blocks cannot be released, the memory occupancy is high, and achieves the technical effect that idle memories are automatically recycled.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method for managing a memory pool. Background technique [0002] During server development, sometimes you will encounter scenarios that require frequent applications to release memory. If you apply directly to the operating system every time, it will not only be inefficient, but also cause memory fragmentation. Many libraries have implemented memory pools for this. , That is to apply for a large block of memory (block) from the operating system, and then divide it into small blocks (chunk) for management. The user applies for memory from the memory pool, and returns it to the memory pool when it is released. The memory pool always retains a large block of memory, reducing and The interaction of the operating system improves the efficiency of dynamic memory allocation. [0003] In practical applications, in order to meet the high-efficiency characteristics of dynamic memory a...
