64bit vs 32bit question
64 bit code can't run on 32 bit CPUs/OSes by default.

So you cannot run 64-bit setup from within a 32-bit OS nor can you run 32-bit setup from within a 64-bit OS That's a technical issue, and has absolutely no bearing on product availability or requirements. -- Steve Foster [SBS MVP] --------------------------------------- MVPs do not work for Microsoft.

emulating 64 bit divide with only 32 bit datatypes in pure c/c++
The Alpha processor for example has 64-bit registers (Integer and Float), and at least 40-bits of address space (some go as high as 56). I'm not sure enough of the UltraSPARC internals to state, but PPC and it's decendants are heavily 32-bit (except the address space which can be as high as 64-bit).

64 or 32 bit ?
I have two questions: 1) Are there any registry hacks to open up extra available memory mapping space 2) Does windows offer a trade-up program? I mean comon, I purchased vista upgrade for 32-bit, but now need 64-bit. I have a 64-bit version of windows XP just sitting around that I could easily upgrade to Vista-64.

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

Che cosa significa che un processore è a 32 oa 64 bit? Eh domanda non facilissima da rispondere. Allora i processori hanno un input di una "parola" N di bit e ad ogni ciclo di clock possono eseguire operazioni su uno o piu' di quelle parole composte da N bit. Per esempio: immetto in un programma che un valore deve

SUMMARY Re: 32-bit and 64-bit under Solaris 2.7
If you have any experience on porting 16 bit code to 32 bit or even 32 bit to 64 bit, please share your experience, give me some belief :-) The AMD64 will be an easy port. The Itanium line, not so easy. AMD: Using 32 bit registers with a 16 bit assembler was doable, just add the 32bit (db66) flag.

sepparating 32 and 64 bit executables.
I assume it will return the lower 32 bits, but is this right? The long will always be 32-bit signed integer in 32-bit system. For 64-bit it dependents on operating system. For Win64 it is still 32-bit. For most Unix it is 64-bit. So Tcl_GetLongFromObj will return 32-bit integer like int in 32-bit processor.

32-bit or 64-bit ?
And it is 64-bit. Already got a reply to this, but you might notice when running "64- bit" VPC2007 that in task manager it does in fact show as a 32-bit process. This is because the "64-bit" VPC2007 simply has the necessary 64-bit drivers; the actual GUI application is 32-bit. Also, VPC2007, no matter what version,

If someone is after performance they'll use a 64-bit binary anyway. If someone wants a 32-bit /bin/ls then they're a corner case. I want performance on 32-bit binaries. Why? Because I use 3rd party software that's not built for Opterons. Sometimes my 32-bit stuff needs a small amount of memory, sometimes a lot.

You have 32 bit. 64 runs on Itanium based systems - and you'd know if you have them, and they'd probably be under the care of an IT department so you wouldn't have to worry about it... Anything on a home system, anything bought in a store, anything under $3000 is definately running 32 bit.

Why is this, and how can i install the 64-bit version? (Using internet installation)?
