[Gems-users] configuration

["Íõ×ô" <qiushui@xxxxxxxxxx>]

I use the MESI_CMP_directory protocol.

And I get these configuration by ruby0.dump-stats:

Directory_cache_latency:6

Cache_response_latecy:12
L2_response_latency:6
L2_tag_latency:6
L1_response_latency:3

Directory_latency:80

what Directory_cache_latency means? I guess L2 holds directory information for L1,
so called directory cache, am I right?

Is there any difference between response latency and tag latency? Why L1 does not
give the tag_latency?

What is Cache_response_latency?

Directory_latency is referred to the off-chip directory, am I right?
