Embodiment Construction
[0018] The present invention will be further described below in conjunction with drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.
[0019] Please refer to figure 1 as shown, figure 1 It is a flowchart of a lock-free multi-thread data synchronization method provided by an embodiment of the present invention.
[0020] In this embodiment, the lock-free multi-thread data synchronization method specifically includes the following steps:
[0021] Step S101, the main thread receives a message, and dispatches and processes the message.
[0022] Step S102, the main thread judges whether the sub-thread is in a suspended state or a dormant state (sleep), if yes, execute step S103, otherwise...

Abstract
The invention discloses a lockless multithread data synchronization method. The method includes the following steps that A, a main thread receives information and dispatches and processes information; B, whether child threads are in the suspended state or not is judged, if yes, the step C is executed, and if not, no operation is executed; C, the main thread creates a queue 1, files in the queue 1 are copied to a queue 2, and then data in the queue 1 are eliminated; D, a signal object is set through the main thread to be in the state with signals; E, the child threads obtain signals, traverse files in the queue 2 and circularly call and load objects, and the created objects are inserted into a queue 3; F, whether the child threads are in the suspended state or not is judged, if yes, the step G is executed, and if not, no operation is executed; G, data in the queue 3 are copied to a queue 4 through the main thread, and the data in the queue 3 are eliminated; H, the created objects are inserted into the queue 1, and the signal object is set to be in the state with signals. By means of the lockless multithread data synchronization method, the problem that deadlock phenomenon happens to access objects of the main thread and the child threads is solved.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a lock-free multi-thread data synchronization method. Background technique [0002] With the development of computer systems, the rendering function of a graphics processing unit (Graphic Processing Unit, GPU) is liberated from a central processing unit (CPU). This greatly improves the speed of graphics drawing. In the past, all calculations for image rendering were done by the CPU, and the reconstruction speed was slow, making it difficult to meet the requirements of real-time rendering. However, the continuous improvement of computer graphics hardware performance has made it possible to use graphics processing units to perform real-time interactive operations on data. In the application program, each application program is a process, and the process is composed of one or more threads. Without threads, the resources of the process cannot be utilized by the CPU. For an appli...
