Hi,
I’m planning to install openSUSE 11.3 on my iMac, which is capable of running both 32bit or 64bit OSes.
I downloaded both 32bit openSUSE and 64bit openSUSE, so which should I install on my iMac?
BTW, what are the differences between 32bit and 64bit openSUSE(v.11.3)? Will my linux run faster if i install the 64bit openSUSE?
Thanks in advance.
Ed

Good question. Look at the currently-running “64 bit, is it really worth
it? Or should I go with the 32?” thread in the 64-bit forum for a bit of
discussion on the same, or search through the forums for the same
discussion as it has come up several times in the last year alone.
Differences: Architecture. If that doesn’t tell you all you need to know
it probably doesn’t matter which you choose. x86_64 is backward
compatible with x86_32 so nothing really lost there plus you can use more
memory and can have better large-number handling with x86_64. In a VM,
though, you probably don’t allocate huge amounts of RAM or doing lots of
processing. I’d still go 64-bit just because it’s the future (and the
present, and a large part of the past which is why I’ve been running it
for six years now on various boxes) but that’s just me.
Good luck.

i know some of the intel based imacs have issues booting to x64 boot discs dispite having full 64bit capable hardware. i know this is true on the earlier aluminium imacs and win7 x64 and is down to the EFI firmware.
just something to note if your have issues booting. i believe it’s an issue down to x64, rather than a specific OS version.
Hi,
I’m a newbie at Linux. So I probably will just use my openSUSE to “surf the web”, “rip and store songs from cds”, or “send and receive mail.”
Which means I probably will just use the “programs” bundled with openSUSE(v.11.3).
So is it better for me to install the 64bit on my iMac? if I don’t need to consider other program whether can run in 64bit.
I tried to run my mac os x(snow leopard) at 64 bit, but soon find out that the system cannot handle some 32bit programs. so i reinstalled the 32bit version of Snow Leopard
last question: if i only uses the software that are bundled with the opensuse, will 64 bit better for my computer 2.4GHz Intel Core 2 Duo 4GB 800MHz DDR2 SDRAM
Will it run faster, or more robotic?
Thanks.

Typically problems booting 64-bit when using 64-bit hardware is specific
to virtualization. If your processor does not have the AMD-V or Intel VT
stuff in the actual processor then you can run a 64-bit OS but you cannot
virtualize 64-bit. This is a hardware issue and affects all platforms as
a result. Check with your processor specs for details.
Good luck.

Unless you’ve got more than 4Gb of memory or specific applications that
need 64bit, I would choose 32bit.

If 64bit capable, take 64bit. No reason not to do so. The OS will make full use of your system’s architecture.
Some remark: 32bit kernel-desktop has PAE built in, and hence can handle > 3 GB.
Hi,
64 bit won’t cause you any problems (that can’t easily be solved), many
of us have been using 64 bit openSUSE for a long time with minimal
issues. But there are occasionally issues, so if you aren’t going to
gain much and you aren’t too comfortable with GNU/Linux yet, I’d suggest
32 bit.
But don’t worry too much about it, and remember the openSUSE community
is always there if you need help.
Regards,
Barry.

There are at least two -
there is no 64bit flash, so on a desktop, you need to do some fiddling
to get it working with 32bit instead. 64 bit java used to be a problem
IIRC, but I have not looked at that for quite a while.
if you’re running lots of processes, you will likely hit the memory
ceiling faster with a 64bit system, because all pointers are twice the
size. I have a number of mailservers that regularly run hundreds of
postfix processes - this is far more efficient on 32bit.
The choice 32/64 bit is the usual - if it doesn’t give you a benefit,
why change?

Albeit slower, but probably not noticable to the casual observer.

Example:
one of my backend mailservers is being hammered right now - it’s an AMD
3800+ with 1Gb RAM. It’s running 864 processes, mostly smtpd. With
32bit, those 800 proceses use a lot less memory so I get to run more of
them than I would have with a 64bit os.
