Hi I am trying to run ghb prediction applied over L3 cache. While running the simulation, I have following configuration on L3 cache which is depicted on config.ini which I got after simulation.
Part of config.ini containing info for L3 cache where I have used prefetch_policy to be ghb ::: type=BaseCache addr_range=0:18446744073709551615 assoc=16 block_size=64 cpu_side_filter_ranges= hash_delay=1 latency=8000 lifo=false max_miss_count=0 mem_side_filter_ranges= mshrs=30 prefetch_access=false prefetch_cache_check_push=true prefetch_data_accesses_only=true prefetch_degree=10 prefetch_latency=800000 prefetch_miss=true prefetch_past_page=true prefetch_policy=ghb prefetch_serial_squash=true prefetch_use_cpu_id=true prefetcher_size=1000 prioritizeRequests=false repl=Null size=2097152 split=false split_size=0 subblock_size=0 tgts_per_mshr=12 trace_addr=0 two_queue=false write_buffers=8 cpu_side=system.tol3aBus.port[0] mem_side=system.membus.port[1] I am getting the statistics for l3 cache overall miss rate. But the point is its showing the same value unchanges on both the cases - when I have applied ghb prefetch technique and and when I haven't applied any prediction technique. I am in whimsical situation *why the two simulations(one with prediction technique and other without the prediction technique) gives the same value for l3 cache miss rate*...... Thanks is advance -- Ashutosh Jain
