WebWe propose an adaptive scheduling technique to schedule highly dynamic multimedia tasks on a CPU. We use a combination of two techniques: the ﬁrst one is a feedback mechanism to track the resource requirements of the tasks based on “local” observations. The second one is a mechanism The CPU Manager policy is set with the --cpu-manager-policy kubeletflag or the cpuManagerPolicy field in KubeletConfiguration.There are two supported policies: 1. none: the default policy. 2. static: allows pods with certain resource characteristics to begranted increased CPU affinity and exclusivity on the node. … See more Since the CPU manager policy can only be applied when kubelet spawns new pods, simply changing from"none" to "static" won't apply to … See more The static policy allows containers in Guaranteed pods with integer CPUrequests access to exclusive CPUs on the node.
