Any Quad Powermac Folders?

It goes without saying (and hence, had to be said :rolleyes: ) that as soon as someone starts folding with a quad processor Powermac, we wanna know! Oh, and mc68k will have to write a new script, too.
 
Amen to that! I wonder, the new dual duallies (or dual quads), do they have two or four (four or eight for the quads) WU's at a time? Or can one duallie do one WU and are both processors on one chip working on the same WU?

1 WU per core. The folding app isn't SMP aware in any way. That it's dual core doesn't change anything.

4 WU at the same time (for the Quad) isn't so bad though.
 
But it has eight cores, and folding doesn't support multiprocessing for one WU, because it uses its outcomes of the previous processor cycle for new input. So I wonder... BTW, I really want to know how fast it goes through a tinker if it does uses both cores for a WU.

Umm....sorry to rain on your parade, but it DOESN'T have 8 cores.

I know the whole "quad processor" business is confusing, but it's just two dual-core processors.

Four would be absolutely ridiculous, and ridiculously expensive.
 
Right, just checked with the Apple site, and its time I get a cup of coffee here on this sunday morning. I thought Apple had released a 4 processor with each a dual core powermac.... I'm gonna get a cup of coffee now.

Octa-Macs next Tuesday! ;)
 
couldnt you just run 4 instances of the program? the os should handle the work load and distribute each instance to a single core right? let me know if im wrong on this.
 
unfortunately the app doesn't work like that, or you would have to know where to place everything and how to rename it, else the two instances of folding would have a conflict with each other. Therefore mc68k made his own app for the duallies (which works still great!).
 
couldn't you just use InCrease and tell it to run 4 FAH cores at the same time, and one would go to each core? I use the app with my dualie ad tell it to run 2 and it puts one to each processor just fine

I wonder if your script, or stanford's apps for that matter, will run native with the new Intel dual core procs.

I suspect the apps won't... and even if they could run with Rosetta, they'd certainly be dead slow.

(But obviously I can't know for sure, since I don't have an Intel Mac).

my scripts are not compiled, so they should run perfectly (with all variables being the same). the PPC apps on the other hand, will not work. they already have x86 apps for PCs, so it shouldnt be that hard to port a mac app. i bet the folding community boards have some info on the x86 mac platform

i could always go to the apple store and find out for sure :)
