If the linux kernel is modified first and tightly-coupled with this SGI machine, then the scalability of that Linux for commercial purposes can be nullified. WHY? because all OS in this universe can perform good scalability when it has been specially modified first to specific H/W. “Linux scales to some of SGI’s 4096 processor SSI supercomputers.”

And running on, and detecting, 64 CPUs / cores does not mean "scaling". With Solaris and OpenSolaris (and calling it "Slowaris" is really quite counter-productive, and simply makes you look like someone who is only interested in ad hominum attacks and not reasoned debate), you can use the same installation CD to go from a lowly desktop up to a or x4650 or T5440 or E25k.<em>That</em> is scalability: the same, non-special code goes from big to small in a fairly linear fashion. The original post deals with updating the default kernel so Linux can do the same thing. Hopefully in the near-future you'll be able to pop in any random RH/Fedora/SuSE/Slackware DVD and get the same results.

How long has solaris scaled that far? Actually... Has solaris scaled up to SSI computers with > 1025 cpus? I've certainly never heard of it. SLUB was written for these monster SGI machines. Linux scales to some of SGI’s 4096 processor SSI supercomputers.

It was meant to show the blending of philosophies behind the two. What is happening now, is that Linux is trying to gain the major features that Solaris has had, and Solaris is trying desperately to open itself up to the developer community Linux has enjoyed. How long has Solaris needed a package / patch architecture simular to RPM or DEB? OpenSolaris responded with IPS integrated with ZFS. How long has Solaris dropped binary files all over the file system, instead of placing into /usr/bin? How long has Solaris had outdated utilities that didn't come up to par like the GNU utilities? Check out the 2008.05 release of OpenSolaris, and you'll find /usr/gnu/bin in front of the traditional /usr/bin in the default PATH. I bet in the next releases, it will be collapsed all together into /usr/bin. The point of this article, is that not only is Solaris trying to become more "linux like" but Linux is trying to do the same as well. We're seeing a blend of the two philosophies behind the O/S and everyone is going to benefit. It wasn’t meant to be a troll. It was meant to show the blending of philosophies behind the two.

Linux has run on 64 CPU's for years, and just like Slowlaris, it has its share of bottlenecks. What they've done is to remove one of them. As for direct i/o, if you happen to actually use it, it's also been in Linux for years. Again, it's just being *enhanced* here. Sorry, but this article is an obvious troll.
