PreFetch for Intel Xeon Phi – Part 2
by MichaelS from High-Performance Computing News Analysis | insideHPC on (#15WFB)
"An interesting aspect to prefetching is the distance ahead of the data that is being used to prefetch more data. This is a critical parameter for success and can be defined as how many iterations ahead to issue a prefetch instruction, and can be referred to as the distance. A compiler will automatically determine the distance to prefetch, and can be determined by looking at the compiler optimization reports."
