[0125] figure 1 It is an overall flow chart of the present invention, specifically including:
[0126] The first step, initialization: initialize the waiting task set WT to be empty; initialize the active host set H a and off the set of hosts H o ;
[0127] In the second step, after the task dynamics is achieved, cancel the mapping relationship between the waiting task and the virtual machine, and update each virtual machine vm jk The time rt to complete the scheduled task jk , and take the newly arrived tasks and the tasks waiting to be executed as the task set WT to be assigned;
[0128] The third step, according to the task deadline (d i ) in the order of earliest priority, select an unscheduled task t from WT i ;
[0129] The fourth step is to assign tasks to the virtual machines that have been turned on, such as figure 1 A medium-thin dashed box encloses the section by:
[0130] 4.1 assign task t i with each started virtual machine vm jk Pair one by one, and ca...
