Hi,
I ran the latest version of Platform Profiler with the Optane DC Persistent memory in Memory mode and uploaded the result file to the platform profiler webpage (localhost:6543).
In Memory view, I can see the 'Read Hit Ratio / Write Hit Ratio' graphs in 'Persistent Memory Traffic (per DIMM)'.
But What is Read Hit Ratio / Write Hit Ratio?
Memory mode metrics (read miss rate of DRAM Cache) are already shown separately in Memory view.
Also, what is '% of Non-Inclusive Writes to Near Memory' in Memory mode? I'm guessing this is writes which are evicted from CPU LLC (Last-level cache) and entering DRAM Cache. Is this correct?
Q1. What is Read Hit Ratio / Write Hit Ratio in Persistent Memory Traffic (per DIMM)?
Q2. What is % of Non-Inclusive Writes to Near Memory?
Best regards,
Minjae Kim
