  • Patent number: 11474952
    Abstract: Methods, systems, and computer readable media for performing page fault handling are disclosed. According to one method, the method includes: after a translation lookaside buffer (TLB) miss associated with a virtual memory page occurs, identifying, in a page table, a page table entry (PTE) associated with the virtual memory page; determining, using a first indicator in the PTE, that the virtual memory page is not present in a main memory; determining, using a second indicator in the PTE, that the virtual memory page is associated with a valid memory address and that the virtual memory page is capable of using pre-allocated pages; obtaining, from a pre-allocation table, a page frame number associated with a pre-allocated page; and updating the PTE to indicate the page frame number.

  • Patent number: 9571399
    Abstract: The present disclosure relates to an example of a method for a first router to adaptively determine status within a network. The network may include the first router, a second router and a third router. The method for the first router may comprise determining status information regarding the second router located in the network, and transmitting the status information to the third router located in the network. The second router and the third router may be indirectly coupled to one another.

  • Patent number: 8180997
    Abstract: A method, system and computer program product for dynamically composing processor cores to form logical processors. Processor cores are composable in that the processor cores are dynamically allocated to form a logical processor to handle a change in the operating status. Once a change in the operating status is detected, a mechanism may be triggered to recompose one or more processor cores into a logical processor to handle the change in the operating status. An analysis may be performed as to how one or more processor cores should be recomposed to handle the change in the operating status. After the analysis, the one or more processor cores are recomposed into the logical processor to handle the change in the operating status. By dynamically allocating the processor cores to handle the change in the operating status, performance and power efficiency is improved.
