Win2k and Duo/Quad Core

[flahmeshess]

Is it possible for Win2k to exploit Duo/Quad Core Intel Processors ?
Or is Core solely a hardware function independent of the OS ? What
about other Intel latest technology ? Are the OS dependent ? Thanks.

Yes and no - it depends also whether the software used can exploit dual
cores

Sort of, please read some of these articles to see what you are up against.

To a limited extent, yes. It depends on the version of Windows 2000.
2000 is not aware of HyperThreading and Dual Core processors, but the
hardware will present each core as a separate CPU. Likewise, with
HyperThreading enabled (if the CPU supports it) then 2000 will see each
HT core as dual CPUs. So, in theory, a dual quad processor with
HyperThreading will appear as 16 CPUs if everything is enabled in BIOS.
Now, how many CPUs are used will depend on the version of 2000. If I
remember correctly, it will be like this:

2000 Pro - 2 CPUs
2000 Server - 4 CPUs
2000 Advanced Server - 8 CPUs
2000 Data Center Server - 32 CPUs

Thanks everybody. I will try to understand further from the reading
material. But I guess another option would be to move to XP or Vista.

just for curiosity, have you tried "psexec" free utility?

it allows you to start new program, on *desired* target cpu

look at www.sysinternals.com [also available on microsoft]

I'm currently using WIn 2000. If I migrate to Win XP, would I still
be able to install my current application such as Office 2000 ? Or do
I need to purchase new applications ?

Thanks.

In essence XP and 2000 are the same so you should not have a problem. I use
Office 97 on W2k and XP without problems. (No idea about Vista though)

Hope that helps

Thanks Andy !
That was my next questions... what about Vista ? Anyone ?

Office 2000 works just fine on XP. So do many older apps. If they
worked on win2k, the chances are very good that XP will run them too.

I haven't seen enough of Vista to make a judgment call on overall
application compatibility.
