The Linux kernel has been accidentally hardcoded to a maximum of 8 cores for the past 15 years and nobody noticed (thehftguy.com)

From HN:

This article is clickbait and in no way has the kernel been hardcoded to a maximum of 8 cores. If you read the commit [0], you can see, that a /certain/ scaling factor for scheduling can scale linearly or logarithmically with the number of cores and for calculating this scaling factor, the number is capped to 8. This has nothing to do with the number of cores that can actually be used.

Thank you for clarification. I just use RSS feed from HN not the actual site, so I don't see the comments.
