Hi, How do you simulate only for ROI? GEMS used to have "magic break points" but I don't think this exists for gem5? Does anyone know how this can be done in gem5? Thanks very much, Carole On Fri, Aug 5, 2011 at 1:01 PM, biswabandan panda <[email protected]>wrote:Hi, i ran the benchmark named blackscoles with the 2 core detailed model . This is the statistics i was getting for the ROI. Without prefetching ---------------------------- system.cpu0.fetch.CacheLines 61605122 # Number of cache lines fetched system.cpu1.fetch.CacheLines 57299220 # Number of cache lines fetched with prefetching (ghb) --------------------------------- system.cpu0.fetch.CacheLines 185709899 # Number of cache lines fetched (order of 10x) system.cpu1.fetch.CacheLines 203241772 # Number of cache lines fetched (order of 10x) Similarly more misses to L2 . The # Number of cache lines fetched = # Number of accesses to instruction cache Could someone tell me what's the reason behind this which causes this increase in instruction fetches. -- _______________________________________________ gem5-users mailing list [email protected] http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
