Re: [Gems-users] MESI_SCMP_bankdirectory: cache and memory timing parameters

["Ying Wang" <ying.wng1@xxxxxxxxx>]

Thank you Mike!

 

how about these TIMING PARAMETERS in ruby/config/rubyconfig.defaults file? arent they applicable to MESI_SCMP_bankdirectory  protocol?
 
DIRECTORY_CACHE_LATENCY: 6
ISSUE_LATENCY: 2
CACHE_RESPONSE_LATENCY: 12
L2_TAG_LATENCY: 6
DIRECTORY_LATENCY: 80
TBE_RESPONSE_LATENCY: 1

what do these latencies represent?
 
thank you!

MEMORY_LATENCY is defined as a macro in RubyConfig.C (or .h).  It
takes MEMORY_RESPONSE_LATENCY_MINUS2 or something like that and adds a
random value to it to create some variability in the system
