This is Anthony & me battling it out for five days. Then Crunchi blowing by both of us like a Space X rocket. 🚀



Ah , good old Ryzen(s) :) Just give him good cooler and there is no limit :)

Anthony and I are neck-and-neck:

I have been following our toggle back and forth every few hours. LOL !

Last one to report a unit wins. That is where this is headed. :-)

I dont think I will catch you... but I try :)

It seems that when you have more than 4 workers, your L3 cache usage has exceeded your 32 MB of L3 cache.
So your 8 workers are causing the memory subsystem to thrash and all memory requests are going to slow memory, instead of fast L3 cache.

I have no problem with that, and I use 4 workers. But if as you say memory subsystem "fail" why then few cores are double faster then others?

My race fellows are Lord and Crun-chi :)

I put six new instances , but still without my main computers. And we are in the middle of challenge...

I run all tests under Linux and using mprime. Found strange timings but only on 640K and 8 workers, one cpu core per worker (SMT is disabled, Linux is OS) and found no explanation. Any idea?

This machine is dedicated just for crunching and nothing else. Also as you can see in red color, not always same core are faster then rest of them.
