Microsoft to Launch 64-bit Windows on Monday 484

maotx writes "Several news outlets are reporting that Microsoft will officially roll out 64-bit versions of its Windows operating systems on Monday. As compared with existing 32-bit versions: 64-bit Windows will handle 16 terabytes of virtual memory, as compared to 4 GB for 32-bit Windows. System cache size jumps from 1 GB to 1 TB, and paging-file size increases from 16 TB to 512 TB."

      There are a million follow up jokes to this one, but the sad fact is that anyone would engineer a system where this is either possible or necessary. I had a long discussion with a Windows tester one day about code bloat in Windows and he argued that it wasn't a problem because "we got lots of virtual memory and stuff just gets paged out".

    Just wondering. Obviously Solaris, IRIX, Linux, AIX, Mac OS X and whatever other UNIX flavors are out there (well, except for maybe SCO...) have had 64-bit support for some number of years now.

    Is Windows the last major commercial OS to add 64-bit support, or are there others I'm missing?

    (Even if it is the last one, I'm sure Microsoft will tout this as supremely innovative. :)

    • Is Microsoft going to have a similar problem, in that it has a nice OS, but few apps to run on it?


      You know, I was expecting application support to be poor for a while, but as it turns out, XP64 seems to have as much if not more currently available software than NT 3.51 for PowerPC.

      And here I was thinking that I was going to be running the worst-supported Windows platform out there. Heck no. Second worst for me.
    • Is Microsoft going to have a similar problem, in that it has a nice OS, but few apps to run on it?

      I think the idea behind AMD's x64 platform is that you don't have to recompile for it. 32 bit appllications should run on x64 the same as they do on 32 bit versions of XP.

      This also has a lot to do with why Itanium didn't sell. It required new software top to bottom.

      This is a short-comming of the design of 64-bit debian systems. The way Solaris does it is to have 32-bit and 64-bit user-land libraries and utilities side-by-side so that you can run 32-bit and 64-bit binaries on the same 64-bit system at the same time. The debian people chose to break backwards compatibility when they went to 64-bit.

    The submission is absolutely misleading.

    Windows Server 2003 has supported 64-bits (Enterprise Edition and Datacenter edition) since its launch on IA64(Itanium). Before that, they also had 64-bit versions of Windows 2000 Server.

    Windows XP Professional also had a 64-bit version since 2003, again running on the Itanium. However, XP on Itanium was discontinued as no one was using it outside MS testing labs.

    Whats gonna be launched are x64 editions of XP and 2003 Server.
    • The submission is absolutely misleading. Windows Server 2003 has supported 64-bits (Enterprise Edition and Datacenter edition) since its launch on IA64(Itanium).

    With kernel 2.6.11 I had no problem malloc()'ing 2^47 bytes (128TB) ! Memory overcommitting is on, of course. While it seems like an unneeded feature now, remember that W$ limitation means you cannot mmap() stuff >16TB, and this will be a painful limitation in a year or two (1TB IDE disks will soon be launched, I heard).

    In addition, I was _really_ surprised to see that Intel's compiler still keeps "long" to 4 bytes on windows (didn't check, but so says their doc). With NO standard integer type for 64 bit, programming is set to be no fun on x86_64 under windows.

      Well, if you need an int of a particular size, you need to typedef yourself a compiler/platform specific one anyway; this has always been that way. I believe 'int' used to be 2 bytes on most 16-bit DOS compilers. If you're talking about pointer arithmetic and array indexing, you should have been using size_t for those uses all along.

      By the way, the GCC sizes for i386 and x86_64 are:
      int: 4 bytes, 4 bytes
      long: 4 bytes, 8 bytes

        For C99-compliant compilers (and gcc), there is <stdint.h> [opengroup.org] which defines:

        int_least{N}_t uint_least{N}_t

        Where {N} can be 8, 16, 32, and, if supported, 64

        As somebody else noted, c99 also supports long long. Of course older compilers don't have stdint.h. I don't think Microsoft C does either, although I don't have the latest version.

    4-bit microprocessor by a
    2-bit company that can't stand
    1-bit of competition
  • The big reason for going to 64-bit Windows has nothing to do with the word size. The main reason is that AMD64 has shed another chunk of the 8086 instruction set legacy. The IA32 has 8 32-bit general purpose registers, about the same total register storage as the Cosmac 1802... a 4/8 bit microprocessor from the '70s. AMD64 gives you 16 64-bit registers, which is pretty small for a 64-bit machine (Alpha and Power have 32) but big enough to give the compiler room to work in, especially since it's also doubling the number of SSE registers.

    Here's some other computers for comparison:

    PDP-11, late '60s... 8 16-bit general purpose registers.
    VAX, '70s... 16 32-bit GPRs.
    68000, ~'80... 8 32-bit GPRs, 8 32-bit index registers.
    z8000, ~'80... 16 16-bit registers.
    8086, late '70s, 8 16-bit GPRs.
    MIPS, '80s, 32 32-bit registers.
    SPARC, ~'90... 32 32-bit GPRs, but only 8 were really usable as GPRs for the optimiser. Thus has hurt the Sparc's performance.
    Power PC, '90s, 32 32 or 64-bit GPRs
    Alpha, '90s, 32 64-bit registers

    I would say the 4x register-file space increase is going to be far more important than the larger virtual memory.

      Why?

      Because it's a logical step in the advancement of computers.

      I can remember a good 17 years ago debating with a "computer expert" about hard drives. He said that nobody would ever need anything bigger then a one megabyte HDD. I still think about that and smile.

      Back then, nobody could predict the way computers would shape our lives. Now, of course, we know.

      Small steps in the advancement of hardware and software typically don't revolutionize our use of computers, but putting them all together has a dramatic effect. So we've started a shift towards 64 bit. We've got the hardware, and now we're getting the software. Yes, at first it won't be a big deal to the end users, but that leap will ultimately give us more power and flexibility to do more advanced things.

      We've got a lot more we can do with computers, and not just with games. Parsing human speech into text, for example, is currently pretty bad. Being able to recognize features in an image is rudimentary at best. No, a 64 bit OS won't change that, but it will lead to a better hardware and software base to make it easier for developers to approach those goals.

      Moving to 64 bit is not being done "just because", it's being done as a step in the continued evolution of computing technology, which leads to better advances down the road.
