SETI on a G5
Imagine SETI on a dual 2 GHz G5.
We just need a 64-bit OS X version and we're good to go.

Re: SETI on a G5
There are already CLI ports for 64-bit PPCs running Linux as well as the Opteron (Athlon-64). I'm thinking it won't take long.
And yes, it would scream.

Re: SETI on a G5
I didn't find a 64-bit version for Darwin... it'll scream louder in a few weeks.

Re: SETI on a G5
Times! you want times! ok...
as near as i can tell, i have not sat about and watched one go through a cycle, so here is what i know.
On a dual 2 ghz PowerMac G5 Running Panther and 1.5 gb RAM, using SETIDockling, running 2 units, set to a nice of 19 and using apps and and listening to iTunes i send a unit off every 3hours 15 minutes or there abouts
pretty sweet isnt it

Wait! Is that 3:15 per instance or averaged across the two? If that's per instance, then you're getting better than linear speed improvement from a G4. I get around 8 hours /WU /CPU on my dual 1GHz G4. If this is so, then you've given me yet another reason to want to get a G5
You're making it harder to hold out until the second revision
However, if that's the effective time for the machine, then you must've been running some CPU-intensive programs (or <shudder> the G5 doesn't "like" the current sah code
). I sure hope this isn't the case, though

Re: SETI on a G5
3:15 each, i run 2 seti units in the background almost constantly, save when i have to render something. right now im at 96.284% which is at 2:37:20 and the other unit is at 40.305% with 59:11. this is with apps like Maya Photoshop Combustion FCP and iTunes goin(not all at the same time)
pretty sweet!

Re: SETI on a G5
oh here is proof 2:41:12 for one unit

wohoo!!!
imagine SETI@home running on Terascale!(Virginia PolyTech G5 Cluster, that would be 2200 units every 3 hours!)

Oh man!
You're making it very hard for me to hold out for the second revision
imagine SETI@home running on Terascale!(Virginia PolyTech G5 Cluster, that would be 2200 units every 3 hours!)
That would be amazing! Someone ought to convince them to do that for a "burn-in" test

Nice. My P4 @ 3.4 Ghz tunrs one out every 2:40. 1.4 Ghz more to equal the unoptimized G5 on Seti.

Yeah, but it's a P4 - a XP2700 system at 2166 MHz'll do the same job, given low latency DDR333 memory and an FSB bump to 170 MHz. (3.34MHz overclock.)
Pentiums are inefficient.
What's kickass is that the unoptimized G4 paced an Athlon running 200 MHz faster with x86 optimized code in a application that usually scales with clockspeed.
