Abstract:
Discontiguous storage locations are prefetched by a prefetch instruction. Addresses of the discontiguous storage locations are provided by a list directly or indirectly specified by a parameter of the prefetch instruction, along with metadata and information about the list entries. Fetching of corresponding data blocks to cache lines is initiated. A processor may enter transactional execution mode and memory instructions of a program may be executed using the prefetched data blocks.
