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?)."
They have an one-off error in their math, it's actually 9 times a 6 core CPU. So, at 42 cores a rewrite is needed.
640 cores ought to be enough for anybody . . .

What does "(Windows?)" even mean?
I read that as saying "Windows is the new Linux!". Clearly the submitter is trying to incite violence in the Slashdot community.
Take it to the limit, everybody to the limit, come on, everybody fhqwhgads.
I'm still waiting for Windows to work well on ONE.
... from the original MIT article it sounds like there is lock contention on shared memory reference counts. ... but I'm making that up.

Don't bother checking the box, RMS, we know who it is.
Nobody's every going to need more than 640 cores

Stay tuned for some shock and awe coming right up after this messages!
Fuck, dude, we hurd you the first time. and "GNU Plus Linux" is terrible marketing.

it's to give the reader enough information to decide whether reading the full article is worth it.
We are supposed to read the articles? Why didn't anyone tell me about this before?!!
Well, there's spam egg sausage and spam, that's not got much spam in it.

Windows, the new Linux.

Lets drive the greenhorn OUT! No filthy high UID's with their spelling and gramar and solid well researched non-sensationlist writing. I want my editors to rape the language (bonus points if it is several languages at once) and sent my heart racing by raising my bile and fear of the unknown and known.

Wow, you've convinced me. I'm canceling all my plans to migrate to OS/2. Thanks.

However, posting your own post in your own post is a bit excessive, and there could have been better ways to do this than just repost your entire freakin story as the first comment.
Yo dawg, I heard you liked my post so I put a post inside my post so you could enjoy it while you're enjoying my post!

SGI runs Single System Image Linux systems with over 1000 cores, that's not the problem.
640 cores should be enough for anyone.

If you have 4,096 CPUs I don't think that "smooth flash playback" is a problem.
4,095 CPUs however...

Nah, jokes like "64xx should be enough for anybody" actually suck the humor out of the reader due to old age. The GP is probably an inmate in the Home for the Terminally Bland.

Calling someone a "hater" only means you can not rationally rebut their argument.
