32-bit apps and multithreading on 64-bit Server 2008

Okay so I read about how 32-bit apps can only use 1 core on 64-bit XP (like Photoshop etc).

Is is the same for Windows Server 2008?

As I would like to start using 2008 64-bit before CS4 comes out.

I would assume that woudnl't be the case, as Server 2008 is based off of the same kernel as Vista, and Vista's multicore/threading support is supposedly a lot better than XP's.

--edit--

Of course, as per usual I have no actual evidence to base my claims on, just sneaking suspicions and semi-logical conclusions.

So a 32-bit app uses all cores on 64-bit Vista?

If it supports multithreading, it can.

When I run SuperPI, it uses some of each of the processors. it doesn't use 100% on each, but the single process is spread across all four cores. Although the lack of 100% is probably because of memory bandwidth restrictions or something.

Likewise other apps, if they are programmed properly, can run on more than one core, regardless of architecture. *

* assuming my theories are correct, and the evidence I use is not merely a reporting glitch in task manager and SpeedFan.

sweet, guess i dont need to wait for CS4 of Photoshop, Premiere and After Effects :)

Silly question, but why are you using server 2008 to run photoshop?

Yeah, it seems silly. Server 2008 might be based off Vista, but it has many, many optimisations and tweaks to make it perform better in a multi user environment.

Just get Vista 64. It will make your life much easier, and perform much faster. Not to mention it's a fraction of the price.

I'm running XP x64, and tonight I intend giving 2008 a whirl. I hate Vista, it's on par with winMe - especially the x64 variations. the latest glitch is not recognising that my 28" LCD runs at native 1920x1200, it fucks up with DiRT, GRID, and just crashes with V8Supercars3, and that's just some of it - even the latest (June) disc is no better, I've been having probs with my last 2x CPU's, last 3x mobos, and last 2x graphics cards (ATI and nVidia)
I haven't come across such a PoS since winMe.
XP Pro x64 all the way!

No. Just, no.

I'll concede that Vista has features enabled that 2008 doesn't, but nothing that can't be disabled.

But if you really want to run 2008 as a workstation, take a look at this article.

Id just like to say thats rediculous

I got Server 2008 x64.

Photoshop, Premiere, everything performs better, the OS itself performs better, with aero and all.

That just means you don't know how to turn stuff of in Vista.

This is oh so wrong :P

Basically superPi doesn't use 100% of all cores because it's intention is to use 100% of one core. It's got nothing to do with memory bandwidth constrictions, it's a single threaded application, therefore it will only utilize one core, or all cores but no more than 25% of each at one time.

The whole idea of SuperPi is to test the processing power of the CPU, and that would not be a fair test if you could use more than one core. This is what makes is a good benchmark in terms of testing raw computing power as apposed to other computers. This is also why a higher clocked dual core of the same architecture will get a lower number than a quad core.

:-)

If an application isn't multi-threaded it will never perform better on a multi-core system.

What you will find is that the system itself will handle the high load produced by the application better.

The CPU schedular in the Vista kernel is much better than the XP kernel, so it can handle load balancing more efficiently.
That is really all you're going to notice. An OS can't multi-thread a single thread ;)

Go look at some bench comparisons, this has been done to death.

I've found the same thing with 2003 vs XP, 2003 is just... better.
