Abstract

The invention relates to the technical field of I / O request processing, and provides an asynchronous I / O request scheduling method and device, electronic equipment and a computer readable storage medium. The method comprises the steps that in response to a detected newly-added I / O request, I / O request time information of the newly-added I / O request is generated, and the I / O request time information comprises expected pause time and expected processing duration; predicting and setting the expected pause time and the expected processing duration of the newly-added I / O request, and caching the newly-added I / O request and I / O request time information; and in response to the detected I / O request execution operation, screening out target I / O request time information from the cached at least one piece of I / O request time information, and processing a target I / O request corresponding to the target I / O request time information. According to the embodiment of the invention, through the steps, the technical problems that the processing efficiency is reduced and errors occur when the I / O requests are operated in a large quantity in a short time can be avoided.

Description

technical field [0001] The present application relates to the technical field of I / O request processing, and in particular, to a scheduling method, system, electronic device and medium for asynchronous I / O requests. Background technique [0002] With the development of application requirements and the improvement of computer processing capabilities, the scale of data processed by applications continues to increase, the amount of data read from or written to files increases sharply, and the overhead of data input / output (I / O) gradually increases. become the performance bottleneck of the application. The existing technology includes asynchronous I / O technology, that is, after the application starts the data I / O operation, it does not need to wait for the completion of the data I / O operation, and continues to perform other calculations of the program, so that the program calculation overlaps with the data I / O. conduct. Since the issuance of I / O requests is usually not uniform...
