The cache simulator can be used to analyze the stream of last-level cache (LLC) miss addresses. This can be useful when looking for patterns that can be utilized in software prefetching. The current analyzer can only identify simple stride patterns, but it can be extended to search for more complex patterns. To invoke the miss analyzer, pass
miss_analyzer to the
-simulator_type parameter. To write the prefetching hints to a file use the
-LL_miss_file parameter to specify the file's path and name.
For example, to run the analyzer on a benchmark called "my_benchmark" and store the prefetching recommendations in a file called "rec.csv", run the following:
