Processors

[gregy4]

For Intel processors exists MBM (memory bandwidth monitoring) available in linux through linux perf utility so I can see actual memory bandwidth. Is similar utility available also for AMD processors, specifically threadripper ?  It would be very valuable for me to know that memory bandwidth affects in negative way my calculations or there's no such problem and I don't need to care about number of memory channels and used cores.

Not sure if this is what you are looking for. It works for Intel and AMD Zen and ARM processors from Github: GitHub - RRZE-HPC/likwid: Performance monitoring and benchmarking suite 

From above link WIKI: Home · RRZE-HPC/likwid Wiki · GitHub 

NOTE: If you already know about this program then disregard my reply or it doesn't do what you want.
