Scheduling method and system for shared storage space

Abstract

Embodiments of the present invention provide a scheduling method and system for a shared storage space, which relate to the technical field of data processing. The shared storage space is adjusted according to the resource block information of the shared storage space, and the shared storage space can be dynamically scheduled according to the size of the data stream to achieve The effect of neither losing data nor wasting shared storage space. The method includes acquiring resource block information of each shared storage space, the resource block information including the number of free resource blocks in each shared storage space, the number of access times of readable resource blocks, and the last access time of readable resource blocks , at least one of the state of each resource block; according to the resource block information, perform an operation on the shared storage space, the operation includes allocating a new shared storage space, changing the state of a readable resource block, and reclaiming the shared storage space At least one of the spaces. The technical solutions provided by the embodiments of the present invention are applicable to the management process of shared storage space in data storage.

Description

【Technical field】 [0001] The invention relates to the technical field of data processing, in particular to a scheduling method and system for a shared storage space. 【Background technique】 [0002] In the field of medical technology, in the image processing process of the imaging system, it is often necessary to realize the interaction of data streams between processes through shared memory. For example, in an X-ray imaging system, after the tablet process collects images, it needs to be sent to the Pipeline process for image optimization. After the tablet process creates the shared memory, it interacts with the data stream of the Pipeline process through the shared memory. [0003] In the prior art, a memory with a fixed size is only created by processes that interact with data streams in the imaging system. During the use of shared memory, the size of the shared memory cannot be changed with the size of the data stream. When the memory is insufficient, a new shared memor...

AI Technical Summary

Problems solved by technology

During the use of shared memory, the size of the shared memory cannot be changed with the size of the data stream. When the memory is insufficient, a new shared memory cannot be created, and when the memory is excess, the excess memory cannot be deleted. Currently, it can only be changed by reconfiguring parameters. Shared memory size

[0004] When the size of the data stream that needs to be interacted cannot be specified, a shared memory of a corresponding size cannot be established according to the configuration parameters, thus causing the following problems in the prior art. During the use of the shared memory, if the shared memory is too small, data may be lost. , and waste memory space when the shared memory is too large
