      Quickly googled up a link from eWeek [eweek.com]:

      As Apple Computer Inc. draws up its game plan for the CPUs that will power its future generations of Mac hardware, the company is holding an ace in the hole: a feature-complete version of Mac OS X running atop the x86 architecture.

      There have been rumors of the move to x86 for a while. I'm not sure if I buy them -- that's a ton of QA overhead for a potential move down the line, and hopefully the G5 negates any reason for them to move. Not to mention if Apple swapped processors, all the AltiVec-optimized code would be worth creee-ap without having multiple processor *types* in each new, partially x86 powered Mac. And any way you cut it, Apple would still, I'd assume, stick some hardware dongle in there to do what Open Firmware does now: stop cheap generic hardware (or expensive hardware when you talk Pegasos [pegasos-uk.com]) from running OS X easily. Apple is a hardware company too, you know. Solutions, not just software, etc.

      But the point of the article stands, even if the author was overhyping. Anil (the author) really has two outs:

"Vanderpool doesn't eliminate the need for virtualisation software, but it's going to make it perform a lot better," says Mike Ferron-Jones, Intel's manager of advanced technology marketing at Hillsboro, Oregon.

      Certain properties of the x86 architecture make it a hard chip to "virtualize" (sort of partition the processor into two virtual processors), which is what VMWare does. Chips can be designed specifically to be easily virtualizable, making applications like VMWare almost trivial to code while being much, much faster. If Intel does somehow retrofit virtualization capabilities onto a x86 chip, it could be a big boon for Linux. An open-source VMWare clone could be written quite easily, and it would run Windows almost as fast as it would run natively.

      Why would this require a hardware solution?
      Speed and better transparency. Dedicating hardware to a process will usually relieve resources used by the system as well. Think of it like the advances in graphics. It used to be that OpenGL was rendered by software for most Windows NT users. I remember getting GLQuake to run at 12.5 frames per second and being stoked. Then along came the dedicated hardware (to the consumer at least). Suddenly 12.5 FPS was a joke and new and shiny features were added/enabled (GLQ runs at 300+ FPS on my GF2 card now and has blended shadows, colored lighting and fog).

      I believe that this architecture may do the same for virtualization and make it truly reasonable to run real-time apps under multiple OSs without the hickups of today. I could then theoretically run Apache/POP3/DNS on the very same box as Active Directory/SQL Server/.Net without many problems - great for a small test environment. Eventually, the hardware might become small/portable and you could start to think of hand-held devices with multiple operating systems or functionalities. The manufacturing and testing industries would love such a device.

    • Why do I need a floating point processor? Using integer math, I can emulate floating point operations. Why do I need protected memory? I could write software to do that. Why do I need hyperthreading? My OS already multitasks.

      Though all of the above can be accomplished in software, sometimes it's more efficient to implement a solution at least possibly in hardware. VMware is notorious for taking performance hits.
    • > You mean like WMWare [vmware.com]? Why would this require a hardware solution?

      No, not like VMware, like a CPU.

      VMware will not pass most hardware through to the guest system. It generally emulates hardware no less (NIC, sound, graphics) and thus if you cannot support vmwares hardware, or need to use hardware not in vmwares list, you are screwed.

      A real CPU will not have these problems.
    • You mean like WMWare? Why would this require a hardware solution?

      Hardware solutions are almost invariably faster. If you can natively run two OS's at once, why wouldn't you, compared to running one in hardware and putting a VM wrapper around the other? Whenever you virtualize hardware, you'll lose speed and, to a degree, incompatibility. For a trivial example, try gaming through vmware. As of 3.0, directX wouldn't even run (Win 2K vm in a linux host).

    this may be the reason for earlier story about MS wanting to control the BIOS too. So now the competition is between MS and Intel. This looks an interesting fight as both are titans and closely interdependent. Having killed other CPUs by promising a lot and delivering little, MS has put itself in a tight position. It can't fight with intel in the same way it fought with Digital. This is one of the reasons, why MS won't release 64 bit OS until intel gives go ahead (according to some newsgroup articles, people had seen 64-bit windows demo in 1997).

Today, most pre-installed XP machine create single partition covering the entier the disk (many people think this is dangerous specially if the partition goes bad, you could loose all data).

    Intel processors have supported the TSS (Task State Segment) for years. This is an architectural feature that enables true task switching in the processor. No OS or other software I'm aware of has ever used this feature of the architecture. The stated reason why it's not used in Windows is "performance". I can see why that would have been a concern 4 or 5 years ago, but it's not very well quantified. I have no idea at all if Linux makes use of the TSS in a way that differs from Windows.

      Linux used TSS to do task switching in older version like 2.2. The switch to software has been made because : * you can check the data between task switching (E.G. segmentation registers), which cannot be done with far jmp * the time to switch task is about the same, but I it easier to optimize software than hardware...

    Such a hyper-OS would allow people using ordinary PCs to try out alternative operating systems, such as Linux, and the applications that run on them, without giving up Windows.

    Wow. If hyper-OS lets us do such wonderful technological feats, we should all bow down and worship Intel now!

    Or instead we could go back to some really freaking old technology called a "boot disk" to accomplish the same thing. Oh, wait, Knoppix and Lindows, among others, already allow this. Today.

    Perhaps we are going to be able to go back to multi-user computers. This would actually be a real benefit for many people. An AS/400 for the home, replacing all the boxes with a single central box again. Thin clients with wireless networking around the place. If a virus hits OS Instance 1, bring it down and fix it in the background while work is transferred to OS Instance 2. One user can crash and burn without anyone else knowing or caring. Load sharing means that the heavy and light users can peacefully coexist. And small businesses are going to love it. Life was easier in the 80s when they had a single Unix box and half a dozen dumb terminals. Life is going to be easier again when there's a single big reliable box with all the external connections and massive storage, and a few screens and keyboards around the place. No fun for case modders, but then for those of us who believe computing should be as ubiquitous as plumbing, and as unobtrusive, case modding is deeply sad.

    Microsofts security lacks somewhat and this would allow sandboxing via virtual hardware. So I could have one virtual machine running IE in slut mode and my critical apps safe on another virtual machine.


    This will have interesting implications with Microsofts licensing mechanisms. All the virutal machines *should* look the same, and Microsoft shouldn't really care if I run multiple copies of their workstation version on the same desktop. That way, I can clone the OS, apply the latest patches, see if they work without blue screening the system, and then put that system into "production". Just like how they use VM on mainframes.

    • Runs multiple OSes? So what?

      How about running multiple copies of the same OS? Let's say that I'm running a 24/7 application like a webserver. It can run on it's own OS because it always has to be on. It can run totally isolated from the other copy of the OS.

      I can run another copy of the OS on the other virtual CPU to do my daily work. If I happen to screw up something on my work CPU and I need to reboot, I can reboot the work-CPU, leaving the webserver happily running along on the first virtual CPU.

    Vanderpool is the codename for Intel's hardware virtualization technology. It is independent of and different from Intel's plans to put multiple processor cores on a single die. You do not need Vanderpool technology to have multicore, or vice versa.

    I do not speak for Intel. My opinions are not necessarily those of Intel's.

  • The limiting factor in virtualization is that two different VMs cannot get access to the same hardware seamlessly, the drivers just aren't designed that way. You would need your drivers to either be based around a client-server architecture such that one OS ran the server, and a client, and others just ran the client, or to have the hardware support some kind of context switching and locks so that only one OS could get access to the video card at a time, and when you switched between them, the video card w

    Nevermind the fact that to pull off such a claim, you would need to duplicate or time-share every other resource in the system, such as video card, sound card, hard disk, motherboard chipset, yadda yadda yadda. It's just so much easier to wave your hands, get people excited, and claim that this new chip can si

    Disclaimer: I work for Intel (in an area having nothing whatsoever to do with Vanderpool), but the comments here are my own personal opinion. That said...

    I saw a demo of Vanderpool at Intel Developer Forum last month. In the demo, the system with a single processor was simultaneously running some version of Windows playing a media clip (a Simpsons episode) while at the same time on another monitor, another copy of Windows was running and was rebooted in order to update a device driver. The video clip played on.

    My take on this (having never heard of it before I saw the IDF demo) was some sort of hardware-assisted VM. It is definitely nothing to do with multicore, as another Intel compatriot noted here.

    You can read the transcript of Paul Otellini's Keynote where he presented Vanderpool at http://www.intel.com/idf/us/fall2003/conf_info/key notespeakers.htm#tuesday

    I don't know if there were specific presentations on Vanderpool Technology at IDF - if there were, you'll be able to find them at http://www.intel.com/idf/us/fall2003/index.htm after November 2.

    Vanderpool technology is not tied to a multi-core implementation. It's a set of extensions to x86 that make virtualization easier.

    Currently, programs like VMWare need to play some extremely ugly tricks to get virtualization to work due to various issues with x86. This technology will make life easier for those wanting to virtualize the CPU.

    So, just to be clear... Vanderpool and multicore are completely orthogonal.
