John McCalpin's blog » Blog Archive » Optimizing AMD Opteron Memory Bandwidth, Part 3: single-thread, read-only
Following up on Part 1 and Part 2, it is time to look at adding explicit prefetching to try to increase read bandwidth. About Prefetching The AMD Opteron Family10h processors have two different “hardware†prefetch mechanisms, and also allow “software†prefetch instructions. The “core prefetcher†is (as the name implies) located in the processor core, and monitors L1 Data Cache misses. (There is a
