  • Patent number: 10754792
    Abstract: Example implementations relate to persistent virtual address spaces. In one example, persistent virtual address spaces can employ a non-transitory processor readable medium including instructions to receive a whole data structure of a virtual address space (VAS) associated with a process, where the whole data structure includes data and metadata of the VAS, and store the data and the metadata of the VAS in a non-volatile memory to form a persistent VAS (PVAS).
    Type: Grant
    Filed: January 29, 2016
    Date of Patent: August 25, 2020
    Assignee: Hewlett Packard Enterprise Development LP
    Inventors: Izzat El Hajj, Alexander Merritt, Gerd Zellweger, Dejan S. Milojicic
  • Patent number: 10592431
    Abstract: According to examples, an apparatus may include a processor to address a physical memory having memory sections, in which a first set of memory sections may be shared between processes and a second set of memory sections may be specific to an individual process. The apparatus may also include a shared virtual address space register to provide translation for the first set of memory sections shared between processes and a process virtual address space register to provide translation for the second set of memory sections specific to the individual process. The translation for the second set of memory sections may be independent from the translation for the first set of memory sections.

  • Publication number: 20190095242
    Abstract: Techniques for a thread in client process to switch to a server virtual address space are provided. In one aspect, a process may attach to a server virtual address space. A request may be received from a client thread within the client process to switch from a virtual address space associated with the client thread to a server virtual address space. The client thread may switch from the client thread associated virtual address space to the server virtual address space.
