Congratulations! :-) I am looking after AMD Threadripper with 64 cores 2 threads each that will give 128 CPU to the system.. maybe this year I could afford that beast then I will report back after testing :-) In upcoming years variations of RISC-V will provide unheard before number of CPU in a single SoC (i.e. 1000 CPU) at amazing power efficiency and I saw reports of prototype with 3 x SoC of this kind on a single board :-) https://spectrum.ieee.org/risc-v-ai --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
