Problems solved by technology

Among them, there are many reasons why the last task is not executed, such as delay, terminal time is too long, etc., which may cause its execution time to exceed the expected time
If the previous task has not been executed, the next task will start according to the scheduled time, which will cause logical conflicts between serially executed timing tasks and even cause the system to crash; but if the timing interval is set too long, The execution efficiency of serial tasks will be reduced

Abstract

Embodiments of the invention disclose a task running method and apparatus. The method comprises the steps of judging whether process identifier files of other tasks exist or not currently before a target task runs, wherein the process identifier files are identifier files created during task running; if the process identifier files of other tasks do not exist, running the target task; and after the running of the target task is ended, deleting the process identifier file of the target task. According to the technical scheme provided by the method and the apparatus, the next task does not run before the task which is running currently is finished, so that the conflict in task running is avoided and the correctness and efficiency of task running are improved.

Description

Technical field [0001] The invention relates to the technical field of operating systems, in particular to a task running method and device. Background technique [0002] In the LINUX system, different tasks may need to share the same program function module. In this way, if the other tasks start before one of the tasks ends, it is likely to cause conflicts and errors between tasks, thereby affecting the efficiency and efficiency of task execution. Correctness. For example, for multiple serially executed timing tasks, if the timing interval is too short, it is likely that the next task will start before the previous task has been executed. Among them, there are many reasons for the failure of the previous task to be executed, such as delays, excessive terminal time, etc., which may cause its execution time to exceed the expected time. If the previous task has not been executed, the next task is started according to the scheduled time, which will cause logical conflicts between ...
