Hi all, following
https://www.intel.com/content/www/us/en/developer/articles/technical/remove-memory-bottlenecks-using-advisor.html
in order to better understand whether memory accesses are killing my performance, it appears that I need cache characteristics in order to use the "cache simulation" option for --collect=map
This raises 2 questions
1) is there any option to get actual data rather than a "simulation"
2) where to find the required cache characteristic values (set associativity, cache line length, number of cache sets) for the given processor. I thought Intel Advisor itself would query this, or there would be something akin to /proc/cpuinfo file that has this info. However, I've not been able to find the info. (The processor is "Intel(R) Xeon(R) Gold 6230 CPU @ 2.10GHz")
With thanks, Michael

For the Integrated Roofline Model, Intel® Advisor collects integrated traffic data for all traffic types using cache simulation.
An article can be referenced as follows:
Cache characteristic values can be set in the GUI path below:
Project Properties > Analysis Target > Memory Access Patterns Analysis > Advanced > Enable CPU cache simulation
