Webb3 feb. 2024 · Abstract: The last-level cache (LLC) is the last chance for memory accesses from the processor to avoid the costly latency of going to main memory. LLC management has been the topic of intense research focusing on two main techniques: replacement and prefetching. However, these two ideas are often evaluated separately, with one being … Webbprefetching on SMT processors. Unlike SMT and VMT, which share many critical resources, Chip Multi-processing (CMP) processors limit sharing, for example, to only the L2/L3 cache. While the restricted resource sharing moderates the benefit of helper threading to only L2/L3 cache prefetching, it also avoids the drawback of hard-to- lego friends olivia tree house
