Hi,
In the cache configuration files such as l2_cache.conf, there is a
parameter "LATENCY" for each level. What is the unit of the parameter, CPU
cycle or ns? I guess it is CPU cycle for caches, and ns for memory option
after reading the source codes. If I am right, the latencies for L2 (5
cycles) and L3 cache (8 cycles) shown in the example configuration, have big
difference from real machine which are about 10 cycles for L2 cache and
about 38 cycles in Nehalem architecture. Since most people use the default
configuration, it is valuable to make sure of this issue.
Thanks.
