Abstract

The embodiment of the invention provides a method and a device for obtaining an optimal number of threads, which relate to the technical field of data processing. The method is applied to optimizing the number of threads. The method includes: obtaining the thread switching loss ci of each step; and according to the relationship of the thread loss ci of each step, the time consumption ti of a single thread and the total time consumption T of steps, the optimal number ni of threads of each step is obtained by calculation. According to the relationship of the thread loss ci of each step, the timeconsumption ti of a single thread and the total time consumption T of steps, the optimal number of threads of each step is obtained, so that the number of threads can be automatically allocated, therunning time of each step is shortened, the conversion time is shortened, and the efficiency is improved.

Description

technical field

[0001] The present invention relates to the technical field of data processing, in particular to a method and device for calculating an optimal number of threads. Background technique

[0002] Existing technologies include multiple conversion processes during data processing. Each conversion process includes multiple steps. The steps are generally executed sequentially through certain logic. Each step will enable a separate thread by default, and each step runs simultaneously. , if a part of the data is processed in the first step, it will be directly passed to the next step for processing. When processing the conversion, you can perform single-threaded processing for each step or manually add the number of threads, but the complexity of the steps will lead to unreasonable resource usage, and complex steps will block the entire process.
