1 results about "Two-level scheduling" patented technology

Two-level scheduling is a computer science term to describe a method to more efficiently perform process scheduling that involves swapped out processes. Consider this problem: A system contains 50 running processes all with equal priority. However, the system's memory can only hold 10 processes in memory simultaneously. Therefore, there will always be 40 processes swapped out written on virtual memory on the hard disk. The time taken to swap out and swap in a process is 50 ms respectively.

An unmanned aerial vehicle cluster simulation scheduling method for time-sensitive target tasks

The application relates to a UAV cluster simulation scheduling method for time-sensitive target tasks, belonging to the field of UAV clusters. The method comprises the following steps: receiving a cluster situation input frame and writing the frame into a time-sensitive cache area; the time-sensitive cache area extracts the latest input frame in a scheduling cycle, and updates a data center according to the latest input frame; a group-cluster two-level scheduling architecture is adopted, the UAV state information of the data center is called, the task area is divided into a plurality of sub-task areas, the UAV cluster is clustered according to the sub-task areas and reaches the sub-task areas in a formation, the UAVs in each cluster cooperatively search in different sub-task areas, when any UAV discovers a time-sensitive target, the remaining UAVs in the cluster are immediately assembled and a surrounding task for the time-sensitive target is issued; the UAV cluster completes the surrounding task according to scheduling output information and the time-sensitive target, and waits for the next task execution. The application solves the problem that the prior art cannot realize a low-lag, sustainable and scalable hierarchical scheduling closed loop.
