Abstract:
A method and apparatus for reducing TLB shootdown operation overheads in accelerator-based computing systems is described. The disclosed method and apparatus may also be used in the areas of near-memory and in-memory computing, where near-memory or in-memory compute units may need to share a host CPU's virtual address space. Metadata is associated with page table entries (PTEs) and mechanisms use the metadata to limit the number of processing elements that participate in a TLB shootdown operation.
