Submission + - Linux May Need A Rewrite Beyond 48 Cores (

An anonymous reader writes: There is interesting new research coming out of MIT, which suggests that current operating systems are struggling with eth addition of more cores to the CPU. It appears that the problem, that affect 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?).
