Physical resource management method and device and intelligent terminal

The embodiment of the invention discloses a physical resource management method and device and an intelligent terminal. The method includes the steps that the total resource usage amount of physical resources occupied by a control group is detected, wherein the physical resources include any type of memory resources, CPU resources, disk storage resources and network bandwidth resources; when the total resource usage amount is larger than a preset first resource limit value, the resource usage amount of physical resources occupied by tasks of the control group is detected; the resource usage amount of the tasks is compared with a preset second resource limit value, and if a comparison result meets an interruption condition, the tasks are interrupted and the resources occupied by the tasks are released. By means of the method, the physical resources can be flexibly interrupted so as to carry out corresponding task isolation or removal operations, and therefore the utilization ratio of the physical resources is effectively improved.
