Abstract

See full text

A method for accessing memory locations includes translating, by a processor, a virtual address to locate a first page table entry (PTE) in a page table. The first PTE includes a marker and an address of a page of main storage. It is determined, by the processor, whether a marker is set in the first PTE. A large page size of a large page associated with the first PTE is identified based on determining that the marker is set in the first PTE. The large page is made up of contiguous pages of main storage. An origin address of the large page is determined based on determining that the marker is set in the first PTE. The virtual address is used to index into the large page at the origin address to access main storage.
