Thank you! With latest commit now cluster/NUMA handling should work and the script should stop logging like crazy with multithreaded 7-zip benchmark on the 96 core machine. Please give it a try, preferably cpuminer scores included: sbc-bench -c :)

Interestingly the ThunderX in the 2nd socket performs slightly better.

Let's do another comparison just for fun since achieving same 7-ZIP-MIPS total score (kinda irrelevant though since the basic assumption that a host with twice the 7-ZIPS MIPS performs twice as fast with 'server stuff in general' is severely flawed with designs that wide and differing memory/individual performance)

That's your king-sized SBC with 2 x ThunderX CN8890 / DDR4-2133:

Now comparing with an Amazon m6g.8xlarge instance based on a 2nd gen Graviton2 (Neoverse-N1) limited to 32 N1 cores clocked at 2.5GHz with some virtualization overhead:

The N1 setup with 1/3 the cores is twice as fast when compressing but achieves 'only' 2/3 at decompressing compared to the dual CN8890 setup (the latter sucking here a bit: CPU utilization only 93% -> 8937/9600).

The Amazon setup really benfits from faster memory access and larger caches:

Interesting. Memory performance might increase a bit in a week or so when I have modules to populate the two remaining channels for each socket.
