    It wont help to post links. Kraftman has confessed he FUDs. Just read his post, and you will see where he wrote it.

    Regarding Linux on 1024 cpu machines and more. Such machines are basically just a cluster of nodes on a fast switch. Read here for more info.


    "Perhaps those benchmarks published by SGI finally deliver a few nails for the coffin of the reasoning of some fanboys that Linux scales better than Solaris, because there are systems with thousands of cores out there. Linux scales on this system exactly like a cluster."

    Not that it helps any, but the Rock chip was s'posed to have up to 256 threads per core and some code in OpenSolaris points to 8 cpu boxes planned on being delivered with Rock chips in them, which according to the register would give 2048 threads/cores:



    "Also of note, we've discovered that Sun's next version of Solaris has been tweaked to handle up to 256 cores with an option to stretch all the way to 2048 cores. (Sun seems to be interchanging cores and threads at this point.)"

    Yeah I know Rock never shipped, and was never ready in time to be the Intel killer it should have been</rant> but the code to deal with that amount of cores and threads is still in OpenSolaris, even if the rock identification specific code has been removed from OpenSolaris around build 122:



    Solaris 7 was the last version of Solaris to only scale to 64 cpu's, Solaris 8-10 scaled to 144 cpu's according to documentation I've seen, and older documents on Sun's website (links from the Oracle site seem to only burn my fingers)

    Yes, that's not talking about 4096 cpu's but the FUD of 64 processors limit on (a straight out of the box) Solaris just hasn't existed in about 11 years.

    Yes, I heard that too. But didnt have a reliable post to show Kraftman. He would just call me a liar and FUDer for writing this, without any links. Actually, it doesnt matter if I show links or research papers, he will still totally ignore them and call me a FUDer and liar. It has happened at several times.

    If you have links about this, please post them for me. Kraftman will just ignore your links and still spread FUD on the internet that Solaris only scales to 64 cpus - which is not true as both you and I have explained. There is no way someone can make him understand he is wrong, even if truth bit him in the back. He will continue to explain to everyone that Solaris only scales to 64 cpus. There is nothing you can do, to make him understand that is false. But if you have links, please show me. I will book mark that link and show it to other people. I want to always back up my claim with links when someone asks. I dont want to say false things, that would be bad.

    "... You can replace every component with the system running"

    Only when you have redundancy ;P

    Yeah, replacing CPU and memory on a running system.
    Hypothetically the NUMA hotplug support is there in Linux, but there isn't any hardware for it on x86. There is no support for the enterprise hotplug capabilities of non-x86 archs in Linux, either.
    When you scale up to big hardware you have no single points of failure... E10Ks, 25Ks, M9Ks, etc. You can replace every component with the system running.

    If we talk about the 1024 cpu Linux machine from SGI, it behaves exactly as a cluster - that is, a network with some PCs.

    Oh, to stop you're bull I say it different way:

    Solaris can scale only up to 64 physical CPUs on a single machine while Linux can scale up to 4096 physical CPUs. I don't care about hyper threading etc. I also don't care I could buy a 106CPUs server years ago and I don't care how many threads Solaris sees.

    The Sun Fire 15K supported up to 106 UltraSPARC III processors (up to 1.2 GHz)
    There's nothing about Solaris scaling up to 106CPUs, I could only buy server with such number of CPUs. Rhetoric and FUD as usual. Solaris scales to relatively small number of real CPUs compared to Linux. I don't care if you're replying me or not.
