Gentoo/PPC64 Beta Live CDs Released

pvdabeel writes "Gentoo/PPC developer, IBM employee and former PPC64 kernel maintainer Tom Gall has announced beta-level live CDs and stages for ppc64. The hardware supported by gentoo-ppc64 is PowerMacintosh G5, IBM pSeries, older IBM 64 bit RS/6000s (such as the model 260, 270, F80, H80, see linuxppc64.org for a complete list) and soon IBM iSeries hardware. Gentoo-ppc64 is the other side of the ppc equation, it is a 64-bit kernel as well as a 64 bit user space. We are the first linux distribution to offer a 64-bit top-to-bottom solution which is not a toy environment. This is a significant and exciting step as there is interest in cluster computing circles, users of java, and more generally those who have needs of large address spaces. It's fairly exciting to be on the forefront and continue to push the capabilities of linux on ppc64 forward."

    Apple never advertised fastest computer, they clearly said the 'first 64-bit/fastest personal computer ever'

    in that sense they are right, Sun, Alpha never made PC's.

    And depending on who's benchmarks you look at, they are the fastest pc's.

  3. Now if IBM had something comparable to a G5 system by Zetta+Matrix · · Score: 4, Interesting

    I don't quite understand why IBM doesn't want to create something like a G5, only "more serious". I'm sure the pSeries machines are excellent, but if they could just lower the price a bit by dropping some of the enterprise features that drive the price up, they could sell quite a lot of them. For people like myself, it's a chance to use a superior architecture in a not-quite-so-proprietary setting (Apple hardware is very proprietary in some areas). We could benefit from the commodity market for all the standardized components and interconnects (DDR RAM, SATA, PCI-X, PCI Express, AGP, USB, IEEE 1394, whatever) without being forced to buy Apple hardware or pay the MS tax. Commodized G5 system running an open source operating system like Linux or *BSD... that's where it's at.

    I know I would like to buy such a machine for myself, and try to convince my employer to buy one for me...

    I am REALLY getting sick of Apple Zealotry about 64bit or fastest computer or best interface or what have you.

    Why, exactly, do you find this so disturbing? Go use Windows or Linux or whatever you prefer and quit stressing. ;-)

    Apple's marketing hype aside, the G5 is a really sweet machine. It'll be even nicer when OS X is 64-bit native. In the meantime, it will be fun trying some of these 64-bit PPC Linux distros in dual boot.

    While I'm proud to hear that Linux has come a long way and now supports more architectures and most other OSes, I'm starting to wonder what's the point. We have Sparc, iAMD64, Power, Itanium, PA and another dozen uncommon architectures out there - and the further you get away from the "standard" i386 the worse support gets. Look at Fedora Core 2 for AMD64 - mysql is 32bit... Try get a JDK1.4 for Sparc Linux... How about Oracle for Linux/Power4?
    While we have dozens of distributions there is not a single 64bit Linux out there that is even close to being as full-featured as debian, fedora, redhat, mandrake,... on i386 are...
    Since 64bit porting is pretty much the same for all platforms, wouldn't it make sense for the distributions to work together in that aspect?

    Why do you need the OS to be "64 bit native"? Fundamentally, all you really need is for the memory APIs to support the full 64 bit addressing mode; the ABIs to support the 64 bit registers; and not much more that I can think of offhand (feel free to correct me).

    User-space utilities don't need to be 64 bit native. In fact, taking Solaris as an example, there's a lot of utilities that are 32 bit apps. Why? They're faster that way. If you only need to manipulate 32 bit numbers, compiling them in 64 bit mode means moving twice as much data as you need to, be it for pointers, integers, or similar.

    It's a different story on x86. There, you have a paucity of general purpose registers; because the 64 bit platform brings additional registers to the table, you gain by compiling in 64 bit mode in order to be able to access those registers. That's the only reason, though. POWER, PowerPC, and SPARC were all designed in such a way that there's no drawback to using 32 bit mode in this regard; they already have adequate registers available.

    In short: know what the cost/benefit of something is before you jump on it, body and soul. Having 64 bit capability is good. Knowing when to use it, and when not to, is better.

    Apple is your best bet for a non server workstation.

    Yes IBM, SUN, SGI, and HP all have taxes on proprietary hardware. Either way your screwed and are paying a tax. Hell I remember installing HP kayaks and telling the user they would have to wait for 3 weeks for special tracks just to mount the cd-rw drives?? (The cdrom-rw was also made by HP)

    Ask anyone who bought ram for an SGI or Sun workstation?

    I was under the impression that new world macs are more open. Jobs saw to that to make more peripherals available to the macs when he returned. This is why Linux runs on them and not older world macs.

    The trick to save money is this. Don't buy the upgrade options from Apple's website. By the ram at compusa or from micron direct. If you want gigantic storage, buy a mac with teh smallest hard drive and purchase the big ones seperately.

    All the macs have affordable 3d opengl cards, SATA, dvd drives -rw, USB and firewire support, flashdrive support, and MacOSX.

    Things a Pseries would not have anyway.
    Its great to use shockwave or photoshop on occasion or to see what a webpage will like like on IE. The dual boot option is nice.

    If you want the IBM because of scsi you can also buy an adeptec scsi adapter or buy one from apple with scsi hardware including raid. They are pricey of course with that installed. Or buy the mac adeptec card yourself and buy the scsi drives seperately like I mentioned above.

    There is nothing these machines wont have that the pseries has. The exception is server oriented features like hot swappable hardware and special more professional 3d cards and ECC ram. But even then I am sure the true 3d support will only be available for AIX.

    Intel might become proprietary too if palidium comes into existance. MS would love to use the hardware to defeat Linux... all in the name of security of course.

    IBM probably wants you to go out and buy a G5 system if you're a home user.

    Think of it, with Apple selling G5's by the boatload, IBM makes cash, plus they don't need to support PEBKAC lusers.

    If IBM sold cheap(ish) G5 rigs running Linux, they would need to support every single moron who calls them up, probably not something they want to do.

    There is nothing wrong with learning a new system. It will make you more well rounded as a computer user and for those doing support and other IT jobs, it can be valuable. If I had a G5 and a few GB of disk space to spare, I would probably install this just to check it out, figure out the differences between it and OS X, etc.

    Now, I imagine there is little reason to replace OS X with Linux, but there is nothing wrong with using both.

    If the G5s had support for ECC memory, then we could use them for modelling without taking a gamble that a flipped bit screws the results.

    When days of computation go into making a calculation, the last thing you want to do is to run it again because there's a non-negligable chance that there was an uncaught bit error.

    Luckily Apple have since seen the light and the new Xserve G5 at least supports ECC RAM. Before that, for affordable scientific computing, dual Opteron machines had no real competition.

    Yes, SLES and RHEL have been around quite a while, and both of them work great. The big difference is "top to bottom 64-bit enviroment". On SLES and RHEL, most of userspace is 32-bit.

    It can be argued that there's any value in having a fully 64-bit userspace. You don't need a 64-bit ls or bash. But you can have them, it's not much slower than 32 bit and it works.
