I used to work on a supercomputer with 128 cores on it that ran Linux (I actually seem to remember it had 256 cores, but someone said the kernel had a limit of 128). This was less than 15 years ago. There were surely many systems just like that one. Does that mean the kernel had been patched? But nobody thought to push that patch upstream?

Reading the other comments here it seems the title is stupid and wrong and my suspicion that this can't be right was correct.
