Linux May Need a Rewrite Beyond 48 Cores

An anonymous reader writes "There is interesting new research coming out of MIT which suggests current operating systems are struggling with the addition of more cores to the CPU. It appears that the problem, which affects the available memory in a chip when multiple cores are working on the same chunks of data, is getting worse and may be hitting a peak somewhere in the neighborhood of 48 cores, when entirely new operating systems will be needed, the report says. Luckily, we aren't anywhere near 48 cores and there is some time left to come up with a new Linux (Windows?)."

The very act of summarization constitutes an act of commentary. You're saying "I think the pertinent parts of this story are these, and the most important questions raised are those."

A good summary invites commentary and frames the questions in a way which makes for better discussion, but don't for a second imagine the OP ought to be value-neutral (if such a thing could even exist.)
