Concurrent task asynchronous scheduling system, method and device

The invention relates to the technical field of computers, and discloses a concurrent task asynchronous scheduling system, method and device, and the key point of the technical scheme is that the system comprises a scheduling manager, a token manager, a task manager, a ring buffer and a consumption thread group; the scheduling manager responds to the calling instruction sent by the calling end and receives a scheduling task; performing token application according to the number of subtasks in the scheduling task; the token manager issues tokens according to the number of the subtasks; the task manager is used for judging the scheduling mode of the scheduling task to be serial execution or total concurrent execution or grouped concurrent execution according to the number of the issued tokens, and executing the corresponding scheduling mode; the annular buffer provides an annular buffer area, and when the scheduling mode is full-amount concurrent execution or grouped concurrent execution, the scheduling task is
