Abstract
A computer-implemented method includes pseudo-invalidating a first Dynamic Address Translation (DAT) table of a DAT structure associated with a workload. A page fault occurring during translation of a virtual memory address of data required by the workload is detected. Responsive to the page fault, the DAT structure is traversed. The DAT structure includes one or more DAT tables, and each DAT entry in each of the one or more DAT tables is associated with an in-use bit indicating whether the DAT entry is in use. Traversing the DAT structure includes pseudo-invalidating each of one or more DAT entries in the DAT structure that are involved in translating the virtual memory address for which the page fault occurred; and identifying a first page frame referenced by the virtual memory address for which the page fault occurred. The data in the first page frame is processed responsive to the page fault.
