How to get each numa node memory bandwidth using vtune command line?

[LisaJ]

Hello,

I want to get the memory bandwidth of each numa node using vtune. I tried the GUI way, which shows me the bandwidth timeline graph in the bottom-up tab under memory usage. Can I also get the raw data through command line?

Something like this: 

`vtune -report timeline -r r000macc/ -report-knob column-by=OvertimeBandwidth -report-knob bin-count=100`

But this is for overall bandwidth instead of each numa node's bandwidth.

Hi,

Good day to you.

Thanks for posting in Intel Communities.

We are checking with the internal team to verify if such a NUMA node filtering is available for timeline reports via CLI. We will get back to you with an update shortly.

Hi,

Good day to you.

Sorry for the delay in getting back to you.

Kindly use the below command for grouping the results based on package (NUMA nodes) and/or DRAM memory channels:

vtune -report timeline -r r001macc/ -report-knob column-by=OvertimeBandwidth -report-knob bin-count=100 -report-knob group-by=UncorePackage

vtune -report timeline -r r001macc/ -report-knob column-by=OvertimeBandwidth -report-knob bin-count=100 -report-knob group-by=DRAMChannel

vtune -report timeline -r r001macc/ -report-knob column-by=OvertimeBandwidth -report-knob bin-count=100 -report-knob group-by=UncorePackage/DRAMChannel

Sample Result:
