Top 5 processor-architecture Open-Source Projects

pcm

4 2,548 9.6 C++

Intel® Performance Counter Monitor (Intel® PCM)

Project mention: Zen 5's Leaked Slides | news.ycombinator.com | 2023-10-08

I don't know how often it's a problem, but I work for a company doing software video encoding, and we always fill up all the dimm slots on servers to have as much bandwidth as possible, even if we have only really use maybe 1/4 of the RAM.
I'm not sure any of the standard Linux tools can show you memory bandwidth usage easily (maybe perf), I know we use Intel PCM (https://github.com/intel/pcm) and AMDuProfPCM (https://www.amd.com/en/developer/uprof.html)
