Fine-granularity resource control method and apparatus

A fine-grained resource control apparatus, comprising a processor and a memory, wherein the memory stores processor-executable programs, and the programs comprise:

• a configuration module, a judgment module and a control module,
• wherein
• the configuration module is arranged to:
• define, for a function of which resource usage is needed to be restricted, a license item in a license file, wherein the license item is used for representing a resource restriction number for supporting the function;
• the judgment module is arranged to:
• judge whether a preferential support command is preset for resources of the function;
• and
• the control module is arranged to:
• control the resources of the function according to the preferential support command, a value of the license item and an actual resource number for supporting the function if the judgment module determines that the preferential support command is preset for the resources of the function, or control the resources of the function directly according to the value of the license item and the actual resource number for supporting the function if the judgment module determines that the preferential support command is not preset for the resources of the function,
• wherein the preferential support command specifies P resources for preferentially supporting the function, assuming the value of the license item is N and the actual resource number for supporting the function is M,
• the control module is arranged to control the resources of the function according to the preferential support command, the value of the license item and the actual resource number for supporting the function in the following manners:
• B. if N≥P, the control module controls the P resources to preferentially support the function, and the number of the occupied resources is not released even if the resources are not initiated or are damaged;
• and then, the control module selects N−P resources that come online first, to serve as the resources for supporting the function, from the remaining M−P resources according to the online sequence, wherein, when N−P≥M−P, all the M−P resources support the function, and when N−P<M−P, the N−P resources that come online first are selected to serve as the resources for supporting the function.
