detailed description

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

The technical innovation of the embodiment of the present invention lies in: mainly based on the current workload and taking the current service workload as input, the scheduling cycle for service optimization is calculated, wherein the scheduling cycle fluctuates between the minimum value of the cycle MIN_INTERVAL and the maximum value of the cycle MAX_INTERVAL.

The system works with the initial scheduling period. When the system workload is high, the scheduling period tends to be adjusted to MIN_INTERVAL; when the system workload is low, the scheduling period tends to be adjusted to MAX_INTERVAL.

By calculating the service-optimized scheduling period, the self-adaptive adjustment of the scheduling period is realized, and the resource utilization rate is effectively improved while ensuring the service response.

in particular:

First, the daemon service sets the initialization scheduling cycle, which mainly includes creating a Load object and completing the initial scheduling cycle setting;

Secondly, the daemon service calls the update_load() method of the Load object to update the scheduling cycle according to the current workload;

When the workload value is greater than the warning value, it indicates that the current service workload is high, and the scheduling period is adjusted to MIN_INTERVAL; otherwise, the current service workload is indicated to be low, and the scheduling period is adjusted to MAX_INTERVAL;

Finally, the daemon service processes the current business request, calls the Load object get_load() method to obtain the scheduling period, and executes the waiting sleep operation to release CPU resources.
