I am new to pcm-memory utility and I am using it for sandybridge E5-2670 processor in linux.
The measured bandwidth in MB/s is the bandwidth for cache access or DRAM access?? I can see that the value shoots up for memory intensive benchmarks but I am confused between cache and DRAM.
Thanks in advance.
It may depend on the version of PCM that you are using, but the source code to the versions I have looked at use the memory controller DRAM read and write counters for memory bandwidth reports.
