I found most of the list online at Macwelt, and added some further programs. Please feel free to add additional applications you know that use both CPUs under Mac OS 9.

Thanks!

Steinberg Nuendo
u&i V-Track
u&i Artmatic

Logic Audio afaik can only run the plug-ins in the seocnd processor (but thats better than nothing)

[IIO]

Quake 3   (fully supports it, but does not run any faster for that matter)

[Mat]

Updated the list. Thanks for the contribution. Perhaps we can become somehow "complete" with this list?
Yes, I read a swell that some other programs do not work really faster wirh 2 CPUs. But some shall get an speed improvement to 180%.

For me it is quite interresting, I diddn´t know that so many professional applications support two CPUs. That makes the Dualmacs immediatly more interresting for me.

[IIO]

yeah well, the 180% faster is probably really only true for some, mainly cubase, performer, and photoshop and after effects.

the latter two only while rendering, since many things you do in photoshop are a matter of in/out.

quicktime and quicktime based apps will also benefit largely from dual CPU.

quake and some other quake 3 eninge based games might even run slower as i heard.

[Mat]

I found an further interresting project with several programs. The "AppleSeed" software for clusterig and parallelization of Macs. It even works with Mac OS 8.5 . It seems to take care of Multiprocessors and later Multicores as Altivec and Carbon.

Very interresting is their "Multiprocessing Development Page":
http://exodus.physics.ucla.edu/appleseed/dev/multiprocessing8.html

The "Power Fractal Software" is their Demo- and Measuring application, available for Mac OS 8.5 onwards:

Sadly I cannot update the list above, else "AppleSeed" and "Power Fractal" should be added.

But there is a big problem:
Only half dozen of this apps have actually some speed improvement.
Typically:
Photoshop, SoundJam/iTunes, Cinema 4D, Cubase VST, and may be a couple more ...

... and the dual Macs (specially the MDDs) ALWAYS have double heat inside that reduce the lifespan of most components, especially Power Sources and Video Cards.
So, we always have avoid to have valuable AGP and PCI cards inside a Dual G4.
... unless we live in the polar regions ... LOL

[supernova777]

so basically.. its not worth it .. to have a over heated system that supports dual processor when really in real world performance the difference was not that much improved.. or worth the risk of damaging hard drives + peripherals due to the increased heat

but still a very informative post from mat + mactron.
thanks for this info guys

[DieHard]

Great Thread guys

Yes, in an OS X or dual boot environment, the dual CPU is the way to go.

In a pure OS 9 environment, there are situations where a user may use one of the supported dual CPU Apps. most of the time, so it is obviously a great advantage to go Dual.

However, in the real world, I found found that some apps run un-stable under OS 9 with Dual CPU support (even if they claim to work properly)... so unfortunately, if I need a specific application that does not support a dual config. and actually runs less stable, then it ruins it for the rest of the list

So Conclusion... for me, a single fast CPU under OS9... hence an Xserve G4 1.33 single in an MDD

[MacTron]

Great Thread guys

Thank You.

Yes, in an OS X or dual boot environment, the dual CPU is the way to go.

Yes, it is, in symmetric multiprocessing systems like those based on Linux/Unix or NT kernels -to name a few- running on high end G5s, X86s or ARMs. But not in a G4, because the system bus can serve well only one CPU, not two, even in the "fast" 166 MHz MDDs. That's why -between other causes- the dual CPU software only show some speed enhancement in PURE CPU task, and those task are very unusual.

In a pure OS 9 environment, there are situations where a user may use one of the supported dual CPU Apps. most of the time, so it is obviously a great advantage to go Dual.

Of course, that's the best idea. If your work heavily rely on task that have a really enhancement in dual CPU, thats the way to go.

I don't have the data now. But you can enjoy an incredible 80% or 90% speed increase with dual CPU encoding MP3 with SoundJam/iTunes, encoding MPEG2 with Apple MPEG2 encoder, or even in Cubase in some workflows, not mine  

But in general, a fast ( or overclocked) single is the way to go in the "G4 world", IMHO

photoshop and cubase are probably the most used programs on MacOS9 ... back in the days as well as today.

RTCW might use 2 CPUs as well, and certainly takes advantage of Altivec.

You are talking about Wolfenstein from 2001?
Was there an Mac OS 9 version at all?

[devils_advisor]

Oh yes there is. Go over to mac garden

The same version works both on Mac OS 9 and OS X.

[Mat]

Indeed! So filipe and you are responsible that I waste all my spare time now with hunting Nazi-Zombies, ... ;-p (Single CPU!)

[filipetolhuizen]

So it uses only one core, but I noticed a huge performance gain when I put a G4 from the Yikes! on my B&W, so it must be because of the Altivec.
