Programs that use both CPUs of a G4 Dual Processor PPC

[Mat]

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.

No no, it uses both CPUs, as it is based on Quake III engine. I am just playing it the last two days with a Single-Core
Interresting that you had a huge performance gain, but IIO said above that Quake doesn´t run faster with a Dual CPU system.

I don't have a dualcore. The performance gain was when I replaced the G3 with the G4.

I see. Sorry for "just scanning" and not reading your previous post carefully.

[IIO]

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

yes, but quake engine in general doesnt see any speed benefit from it.

Jesus Chrysler people!!!! Dual Core is ONE THING, Dual Processor is ANOTHER TOTALLY DIFFERENT THING! You either reffer to it as you should, or give it a rest! If someone came to visit this forum just now and laid an eye on this thread especially on the few last posts, he'd immediately leave under the impression that most people here talk out of their asses and can't make the difference between two different technologies...
I've said it before and i'll say it again. English is not my native language, but i don't go around calling FireWire fireware, or even worse as i've seen in other places with tons of english speaking people, calling it firmware or some stupid crap like that. Get your facts straight! Read a little bit and then post like crazy. Sorry, but i couldn't help myself...

PS: Dual or Multi Core technology is used nowadays in modern systems. But multi chip systems can have multiple multi core CPUs. Have a look at the Mac Pro for instance. Get it?
And by the way, there have NEVER EVER BEEN ANY "dual core" PowerMac G4 systems. Dual CPUs, sure! The first and last PPC DUAL CORE CPUs ever used in Macs were in the PowerMac G5.

Don´t be that hard with us. I belive we all know that there are no "Dualcores" for  Mac OS 9. As you can read above wa all used "Dualprocessor", "2 CPUS" and such terms. Later it evolved from my try to make a joke with "Singlecore" (what still is correct) and then I used once the wrong term Dualcore.
But I am absolutely sure that we all know that there are just Dualprocessor Macs around for 9, and no Dualcores. Of course you are right and we should be a bit more careful about using the right terms.

I am the kind of guy that takes a joke, and a pun! I don't mean to offend anyone, damn, that's the last thing i wanna do. My post was meant both as a joke and as a serious thing. You took it more than well if i may say Thank you for replying, but let us get back to the topic, shall we?

[devils_advisor]

Yes the topic was g4 dualcore

You guys are all drinking too much Coffee

BTW., making your Mac OS 9 Dualcore at least an Hexacore up to an 26x-Core or 58x-Core with a Magma Expansion Box is the Total Impact Card! ;-p

http://www.everymac.com/upgrade_cards/totalimpact/totalpower_g3/totalpower_g3_400.html

To be honest, I have no informations about realworld speed of such Multiprocessorcards cards. The last one seems to be the 4 x 500MHz G4 card, and I read that a usual Magma PCI expansion has not enough power for more than 4 boards, ...

Total Impact stated that 8 cards could be used together with the entire memory mapped into the Linux-Kernel back than.
For Mac OS 8 to 9 they replaced the Mac MP library with an own one, ... as said, I´ve never read anything about real computing power and especially about more than 1 card inside a Mac.

Here is another short info:
http://tweakers.net/nieuws/11875/pci-uitbreidingskaart-met-4-powerpc-g3-g4-cpus.html

One 4 x 500MHz G4 was 6300$ in 2001

btw graveyard, while you are on interpretational sovereignty for terminologies you should include apple inc. into your criticism.

they keep calling their computers "8 core" while in fact the have never been  that.

Talking about dual cores and dual CPUs, has anyone ever seen the ultra rare dual zif bay? I could find something about it some time ago, but now I can't seem to find anything about it anymore.

Are you talking about the PCI Macs or Clones like the 9500/9600 or Umax Pulsar (S900) with 2 604(e) CPU slots/cards?

[Protools5LEGuy]

No, there is a rare Joesomething dual ZIF like for G3B&W and G4 PCI

[Mat]

Ups, I confused the PCI Macs Processor Card Slot with the ZIF. If i wouldn´t use in both slots Sonnet G4 Cards, … ;)

ApplePCI - Apple Multiprocessor and G4 PowerBook Expansion Chassis Fix

Digidesign Pro Tools: there was a Dual Processor OS 9 Fix and a Apple Multiprocessor and G4 PowerBook Expansion Chassis Fix

http://archive.digidesign.com/download/mp/

Apple Multiprocessor and G4 PowerBook Expansion Chassis Fix

This download is for anyone wishing to use Pro Tools on either:

Multiprocessor Apple G4 computers

Titanium Powerbook model 550 or higher with Magma CB2S or other Magma PowerBook Expansion Chassis with an ATTO SCSI card. See the MAGMA MAC Cardbus Expansion FAQ for Magma's information on the new Apple Titanium SCSI Fix and ProTools (including HD) testing.

Without this download:

Users with multiprocessor systems may experience -6042 errors unless they remove the Multiprocessor folder from their extensions folder, thus disabling the second processor.

Users of Titanium Powerbooks model 550 or higher are unable to use a Magma CB2S or other Magma PowerBook Expansion Chassis with an ATTO SCSI card for their Pro Tools hardware.

Other users will experience no benefit from this download and should not use it.

Download Includes:
