The statement looks very misleading or even fraudulent. I used a system with 192 cores often and with GNU parallel, it did not stagnate at 8 parallel tasks for simple demonstrations. If we're talking about a case where 8 is intentionally the maximum (it's possible that some tasks should not parallelize more than 8), then the statement is misleading as well, since it gives the wrong impression. I have the service tag and the output from nproc and the exact version of everything where I used 192 CPUs. I suppose pseudoscience will always return and claim that the statement is true anyway, no matter what observations the rest of the world can give. There is pseudoscience forever who always says that the rest of the world is misunderstood.
