    Abstract: A computer includes a processor and multiple components directly or indirectly connected to the processor. Each component is coupled to a control device, and is configured to provide resources for one or more application programs running in the computer. The processor, when executing an application program, attaches a tag to an application request, and sends the tag-attached application request to a control device coupled with a component to which the tag-attached application request is directed. The control device receives the tag-attached application request, determines, based on the tag and a resource allocation policy, an amount of resources in the component and instructs the component to allocate the amount of resources and process the application request in accordance with the amount of resources allocated for the application request.

  • Patent number: 10241919
    Abstract: A data caching method and a computer system are provided. In the method, when a miss of an access request occurs and a cache needs to determine a to-be-replaced cache line, not only a historical access frequency of the cache line but also a type of a memory corresponding to the cache line needs to be considered. A cache line corresponding to a DRAM type may be preferably replaced, which reduces a caching amount in the cache for data stored in a DRAM and relatively increase a caching amount for data stored in an NVM. For an access request for accessing the data stored in the NVM, corresponding data can be found in the cache whenever possible, thereby reducing cases of reading data from the NVM. Thus, a delay in reading data from the NVM is reduced, and access efficiency is effectively improved.
