CNET: Penguin on 24 CPU StarFire

According to Steve Shankland at CNET, Linux 2.4 scales to 24 processors on Sun E10K, on work performed by LinuxCare but not, apparently, funded by Sun.

The article doesn't cite benchmarks, though Dave Sifry of Linuxcare is quoted saying "They are seeing near-linear scaling [...] the roof's about to get blown out when it comes to Linux 2.4". SMP performance has been one area in which Linux has lagged proprietary Unices, and even Microsoft cites this a shortcoming in their (increasingly dated) Linux Myths page.

24 is great, how about 1? (2.33 / 6) (#20)

Scaling up to 24 processors is supa-kewl and all (well, -cool, even). Unfortunately, I'm probably not going to be able to afford a 24-processor box for at least six months, maybe -- so how does 2.4 perform on a single-processor machine? Does the new locking scheme bog down 1p machines, or is most of the locking overhead reserved for SMP builds only?

For that matter, how does 2.4 do with 2 or 4 processor boxes? More MLP, anyone?

technology wise.. (2.20 / 5) (#22)

technology wise this is pretty cool. seeing the kernel scale to 24 processors.. even if it is an expensive set of 24 processors. =)
