How could I use mlc to do UPI stress and make the percentage utilization of UPI up to 100% ?

[1101claire]

Hi Developers,

I'd like to use PCM Tools to monitor UPI traffic and execute UPI stress on my server. There are two processors(Intel Sapphire Rapids) on my server.
I create a test.cfg and use "./mlc --loaded_latency -otest.cfg -d0 -T -t180" to run UPI stress. But the percentage utilization of UPI get only 54%.

I have some questions that need your help.

Q1:How could I use mlc to run stress and make total percentage of UPI bandwidth get close to 100%?

Q2:Why Max UPI link speed is 35.8 GBytes/second instead of 32 GBytes/second(16 GT *2Bytes/per channel) ?

Thanks.
