Oh Erik, Where is 64-bit Windows Again?
Ved ikke helt, om det betyder noget for mig, om det er 32 eller 64 bit. Har det noget at gøre med, om min processor kører 32 eller 64 bit, og hvordan kan jeg evt. se det? Mvh. Ole .

The nit-picking pedantry bit says "It depends on whether you build with a 32-bit or 64-bit version of CSDK - because a 32-bit CSDK cannot use shared memory That depends on the platform - which you don't mention - but where you have a choice of 32-bit or 64-bit (eg Solaris), the default builds of Perl tend to be

32 vagy 64 bit?
64-bit software. Generally speaking, going from 32-bit to 64-bit code actually makes things SLOWER if all else is equal (which it rarely is). Also, performance of 32-bit chips is likely to be pretty comperable to that of 64-bit chips LOL! Even with a 64 bit operating system and 32 bit software the Opteron and

64-bit IA-32, AMD and all that
Yes.. you could very well run protected mode 64-bit stuff _launched from DOS_, just as you do 32-bit stuff. But keep in mind, that's an ugly hack. And that would require at least a minimal bit of 64-bit support in the 32-bit OS, at least to manage the proper save/restore of registers on task swaps, interrupts,

64 Bit Suse
Using ProcessExplorer, we saw a 64 bits dll listed in our 32 bits process (and, yes, we are sure that this dll is 64 bits). Best regards, Olivier. Are you sure that the 64-bit DLL was a COM DLL? For instance, a 32-bit process loads the 32-bit and the 64-bit of the ntdll.dll, part of each 32-bit process contains

When is 64-bit OS going to be the only windows
Are the 64 bit *instructions* there in the CPU or not? Are the registers 64 bit or not? Absolutely. What does that have to do with a 64-bit _system_? Have you ever tried using 64-bit instructions, on a 64-bit machine, but in a 32-bit system? Well, I've used 64 bit doubles and 128 bit Altivec vectors in a "32 bit

32 vs. 64 bit XP
On a 32 bit machine, these would probably be represented as 64 digit numbers, with each digit being 32 bits. On a 64 bit machine, you'd represent that same number as a 32 digit number, using 64 bit digits. So, if you were using an algorithm whose running time is O(n^2) in the number of digits, you get a speed up by

32 bit oracle on Solaris 9 64 bits ?
For example, if I try to download ncurses5.2 , should I compile it as 32 bit or 64 bit? would 32bit programs running in 64bit kernel will make performance slower/faster ? If so, should I fall back to the 32 bit kernel ? Build user level programs as 32 bit unless they can make use of features only available to 64

Vista 32 bit doesn't require signed drivers. Whether you think that's a good thing or a bad thing is subject to some discussion. ;) Personally, I don't run 32-bit windows any more. 2.) Vista 64-bit has been completely reliable for me and for many others here. I have been running it for 18 months with no issues.

Che cosa significa che un processore è a 32 oa 64 bit? Eh domanda non facilissima da rispondere.

Cheers, -Ali thanks for the info. but why MIPS/SPARC/POWER could run both 32-bit and 64-bit executable without any problem only Intel has the performace issue?? is it because RISC and CISC machines implement their ISA differently, one uses fixed length intruction set and another (CISC) uses variable-length

useing OEM kety to go from 32-bit to 64-bit Vista
64-bit computing only helps for relative large data sets. For many applications which don't need that, they'll run faster under 32-bit mode than they do under 64-bit. For a more specific example, people at Sun have said that 64-bit Solaris run about 20% slower than 32-bit Solaris for classic 32-bit apps.

First I'm wondering, can software written for the 64 bit processors run on our current 32 bit ones? Short answer: No. Long answer: it might be possible to run One thing that I think I should mention at this point is performance of 32-bit vs. 64-bit software.
