    Default Does wrong version work? openSuse11.1 x86_64?

    I have a 2008 Lenovo T61 Thinkpad. I think my processor is Intel Core 2 Duo (this might be on my signature which I can't see while I type this). The research I did said that the x86_64 version of openSuse was the correct version. Not i686 and not i586.

    Also, could an incorrect version cause a slow system? Ie., a 32-bit version on a 64-bit processor (I think the Intel Core 2 Duo is 64 bit) might cause things to take twice as long. Or a 64-bit version on a 32-bit processor might cause things to take twice as long?

    I just recently switched to openSuse 11.1-KDE from SLED 10.3-Gnome. And in the process installed a dual boot system on a new drive with Windows XP SP3.

    So I am able to pop back in my old harddrive when things get screwy, and be exactly back where I was before.

    This one "only" gave me a big grin.

    e., a 32-bit version on a 64-bit processor (I think the Intel Core 2 Duo is 64 bit) might cause things to take twice as long.
    But this one ...

    Or a 64-bit version on a 32-bit processor might cause things to take twice as long?
    made my day ...

    I'm glad I made your day, but I am a bit serious here. Just a bit.

    OpenSUSE 32bit or 64bit - openSUSE Forums try this thread..

    It basically comes down to PC usage for most I suspect little gain to none, but for some they see a marked improvement.

    Not only does your PC need the hardware software needs optimising.
    Man first, have a try at Info, have a look at Wiki, if all that fails Scroogle!!!!!

    Perhaps you should start to inform yourself about what 32bit or 64bit means, using of the search engine of your choice might be a good start.

    Your statements made above are complete nonsense, which you will see when reading a little of what you will surely find when searching the net.

    Compared to cars a "64 Bit car" does not have 8 wheels and runs at twice the speed automatically.

    64 bit processors have been the norm for several years now (I dont think you can buy a 32 bit processor anymore) that said ALL 64 bit CPU's both Intel and AMD are designed to run BOTH 32 and 64 bit instructions.

    You can choose to install either a 32 or 64 bit Operating system, the choice depends on Software Applications you want to use are they 32 or 64 bit. Most applications are still 32 bit as most of the world still run 32 bit OS and that is where the money is. There are vary few 64 bit only apps.

    Abobe Photoshop for example can be had in either 32 or 64 bit the main difference 32 bit apps and OS have a 4 gig memory address limit. 64 bit apps and OS can use more memory and CAN be faster if written to use 64 bit instructions.

    Most Linux distros come in both flavors, Windows XP and Vista also have both 32 and 64 bit versions. (I dual boot Win XP 64bit Edition and OpenSuse 11.1 x64)

    Stephanie,

    First, allow me to address the previous posters. I believe that sometimes the "elite" Linux users, forget, that while we strive to make Linux more desktop friendly, that we might just get people who aren't "computer savvy".


    To answer your questions, 64 bit software(including OS) will not run on a 32 bit processor at all. 32 bit software(including OS) will run on a 64 bit processor, but won't run faster because of it. 64 bit operating systems are a great thing, and use more of the hardware power that is available, but as was hinted at by a previous poster, not only does the hardware and OS have to be 64 bit, the software your running has to be 64 bit, and optimized to take advantage of the 64 bit environment. What this basically means, is I can have openSUSE x86_64, running on a 64 bit processor, but if I am running 32 bit software, than I receive absolutely no performance boost in the software itself.

    While 64 bit Processors have been out long before the OS, and the OS are now starting to make an emergence in the mainstream of things, a majority of the end user software, is still 32 bit. Unfortunately, the "shift" of the software companies is still way behind the rest of the market, for the simple reason of, if you sell a 64 bit program at the store, and someone buys it that doesn't have a 64 bit setup, than they have in essence bought something they cannot use. The software companies aren't going to make the "jump" until they are sure a majority of the market is running 64 bit hardware, as well as OS.

    My suggestion to you, is to go ahead and install the x86_64. It won't "harm" you in any way. To this end, with a 64bit OS, and 64 bit hardware, you can only benefit from it, since the 64 bit OS is backwards compatible with the 32 bit software.


    Sincerely

    I'm a fairly competent software engineer here, so I don't see it as complete nonsense, although if that is the case, I stand enlightened (although rebuffed a bit by my "puzzled penguin" status). Maybe I'm not that competent. I don't know.

    From my electrical engineering degree, I believe a x-bit system has a data bus of x-bits, no? What is your background expert penguin? If a 32-bit app is running on a 64-bit processor, is it not totally nonsense to think that half of the processor data bus is not being utilized? And if 64-bit processors were designed to benefit from 64-bit apps, wouldn't it stand to reason that some overhead is incurred in running those 64-bit apps? And that same overhead would exist for 32-bit apps as well?

    But my situation is a 64-bit processor running on a 64-bit app, so a mute point for me. I still think there are performance issues with ANY kind of "mismatch" between x-bit processors and x-bit apps. E.g., a 64-bit app wouldn't run too well on a 32-bit processor (if it would at all?).

    Well you stated this here:

    The research I did said that the x86_64 version of openSuse was the correct version. Not i686 and not i586.
    Nonsense, one can run 32Bit OS on a 64 Bit CPU (I am doing that right here).

    Ie., a 32-bit version on a 64-bit processor (I think the Intel Core 2 Duo is 64 bit) might cause things to take twice as long.
    The nonsense here is the "twice". Why twice? Because of 2x32 = 64?

    And:

    Or a 64-bit version on a 32-bit processor might cause things to take twice as long?
    Also nonsense, they don't run at all.

    A few years old, but to give you an idea about the real differences for normal apps:

    I thought cynical pride answered you very well.

    No there isn't any problems running 32bit on a 64bit chip, backwards compatability. Now if you google long enough and look at bench marks you just may find a benchmark that runs a 32bit app slower on 64bit(But minimal loss/gain and made up else where). As for the other way yes impossible afaik.

    Now my understanding and limited at the best. Is you have to chop the packet in 2 for a 32bit app in a 64bit OS.

    Perfomance benchmarks with 64bit are all over the place, now not the best source but certainly a good starting point..

    64-bit - Wikipedia, the free encyclopedia

    I really can't be bothered finding the optimisation docs. But as stated earlier there is very few truely optimised 64bit apps. Now I believe but could stand corrected that mplayer has some 64bit optimisation.

    You would need to google optimising for 64bit, to see exactly what is needed.

    Unless as the other thread and wiki said
    While 64-bit architectures indisputably make working with large data sets in applications such as digital video, scientific computing, and large databases easier, there has been considerable debate as to whether they or their 32-bit compatibility modes will be faster than comparably-priced 32-bit systems for other tasks
    And the debate won't be ended in this forum.
    Man first, have a try at Info, have a look at Wiki, if all that fails Scroogle!!!!!
