Hey Smiley

there are some errors or outdated infos in the README.md:

Another exclusive feature of JCE!
❗️ The no-cache mode is available only in the Windows version.
This is the reciprocal of multi-hash: for cases when your have wasted CPU cores, typically when mining Cryptonight Heavy. If you have a Ryzen 1700, 8 physical cores, 16 logical CPUs, 16M cache, the naive configuration would be 4 threads on 4 cores, 4M cache each, total 16M.

"cpu_threads_conf" : 

     { "cpu_architecture" : "ryzen", "affine_to_cpu" :  1, "use_cache" : true },
     { "cpu_architecture" : "ryzen", "affine_to_cpu" :  5, "use_cache" : true },
     { "cpu_architecture" : "ryzen", "affine_to_cpu" :  9, "use_cache" : true },
     { "cpu_architecture" : "ryzen", "affine_to_cpu" : 13, "use_cache" : true },
]
But 8 logical CPUs would be unused. Enabling them would flood the cache and lead to worse performance. What to do is making them mine, but with no cache, direct to memory.
When the Ryzen 7 1700 has 16 logical cores and only 4 are used, then not 8 logical cores are unused, but 12! Wink Perhaps you got confused by your own Ryzen 5 1600. There indeed 8 cores are unused.

Sumokoin, Loki, Ombre, Italo, Bloc, Niobio, Saronite are now Cryptonight-Heavy,
Sumokoin is not Cryptonight-Heavy anymore. They went back to original Cryptonight to be ASIC-friendly, whereas the existing Cryptonight-Heavy chain was renamed to Ryo-currency or simple Ryo.  Shocked
