Hi everyone, I am running the pagerank algorithm that is provided by the GAP Benchmark, and it is well known that pagerank has very bad cache utilization. But when I run the code in GEM5 on one level of cache i get a very low missrate, i.e. approximately 1% and it goes to a maximum of 3% for a graph with 16000 nodes. I test it using the se.py config that is provided with a cache size of 16kb using the TimingsimpleCPU, and the cache missrates are not as expected.
I also use the pseudo-instuctions m5_reset_stats and and m5_dump_stats to test just part that involves the actual pagerank implementation and I still get a very low cache missrate. Would someone be kind enough to explain why this is so, as I am quite confused or is there something that I might be doing wrong? Any help would be appreciated. Thanks, Aamir
