Prefetch line
Cache prefetching is a technique used by computer processors to boost execution performance by fetching instructions or data from their original storage in slower memory to a faster local memory before it is actually needed (hence the term 'prefetch'). Most modern computer processors have fast and local cache memory in which prefetched data is held until it is required. The source for the prefetch operation is usually main memory. Because of their design, accessing cache … WebAug 2, 2024 · Transfer the file to your local system and import the nvprof profile into the NVIDIA Visual Profiler.
