5300 PPD out of a single machine

[Foxery]

A testament to the power of the GPU2 client:

The SMP unit is one of the fast 2653s.

(Note that WinXP handles this combination of clients better than Vista.)

Legoman, how is your dual video card machine working out?

All is working fine besides the constant EUE's on the newer large WU's. I think I've finished 4 WU's successfully out of 10 today. However, when all is working fine, my system earns ~6100PPD.

2 GPU2 clients = 2 x 2500PPD (varies depending on WU)
1 SMP client = ~1200PPD (low, I need to look into this)
total is around 6200PPD.

With both GPU's at 100% and the CPU at 100%, the heat output of my comp is incredible. They're all watercooled and I'd estimate the water temp at around 150F.

2 3870's = ~90w each
Q6600 @ 3.1ghz is ~125w
300w coming out the top of my computer is quite a lot. I can't imagine 2 3870 X2's.

Cool 😎

Or should I say HOT! :evil: 😛 😀

 

[legoman666]

Ah, here we go, some idle numbers from overnight.
GPU0: 2383
GPU1: 2379
SMP: 2116
Total: 6870

My previous SMP number was low because it had a crappy WU. It's now on one of the fast 2653's.

I have a 3870, I assume that this would work even better than the 3850 for the gpu2 core, right? I really like running seti, would I be able to run seti on 3 cores and just use one core to help the 3870 fold?

 

[bryanW1995]

hmmm, well I dl'd the gpu2 client. all's going well, no crazy computer slowdowns like I used to get with my e6750. I'm still running seti on all 4 cores, however. Should I knock seti down to 3 cores, is an x3350 @3.6 fast enough to run seti and fold on the gpu2 client at the same time, etc?

I might end up shunting this 3870 to my mom's Athlon xp 2500+ rig. I could take her off seti since she's only putting out 250 ppd anyway on that rig. crap, n/m I think I have her on an old agp rig...grrrr...

The only thing that matters for GPU2 client speed is the number of stream processors and the core GPU speed. 3850's and 3870's have the same number of stream processors, but the 3850 has a lower clocked core. If you overclocked the core (its ~700mhz stock?) you would see the same output from your 3850 as a 3870.

That said, the 3850 can earn about 2000-2200PPD at stock speeds. And yes, you should be able to run GPU2 on 1 core and seti on the remaining 3.

Bryan, swap your extra Radeon into the machine in your sig with a GeForce 7300 🙂

And yes, if you can tell SETI to only use 3 cores, that would be ideal. If need be, the GPU client also has a setting to run at a priority level slightly higher than Idle, to make sure it gets a CPU core of its own.

Weird. I've sent in 380 GPU2 work units, and not had a single EUE. Ever. I'd love to know what makes my machine so much luckier than everyone else's.

 

[bryanW1995]

I had 2 EUE's right away, but now am fine. Thanks for the help foxery, my numbers are going up very rapidly. don't know what I did, but I'm up to 830.12 using last 3 frames now.

re using one core for f@h: I've noticed in task mgr that f@h core_11.exe is typically at 5-7%. It's had a few dips down to 3 or up as high as 13, but they were very brief. That doesn't seem like it needs an entire core to use, but I'll try that if my output remains substandard.



edit: well, my ppd number shot up immediately when I switched seti to 3 cores. also, f@h immediately took over the remaining core. got up to 2116 ppd within 5 minutes...looks like mom might be getting a pci-e computer for mother's day...🙂

 

[bryanW1995]

Ok, I have a new, EVIL plan to make optimal use of my resources. I fixed my cousin's athlon 64 4000+ last year and got him to run seti on it as payment. I can temporarily use one of my other gpus in my main rig and dump the 3870 in his. My question is, will I still get 2000+ ppd using an A64 4000+ single core instead of one core of my x3350 @ 3.6, or am I going to be hamstrung again by limited computing power? also, is there a way to disable f@h while the computer is in use?

 

[Foxery]

No, the Athlon may be CPU limited on some work units and get fewer points. The GPU client is also not guaranteed to play nicely when you run games, since it's still a Beta, so I would not recommend putting it on someone else's computer.

Also, the deadlines are short enough that the computer needs to be on a lot, and the GPU alone eats ~125 watts, so keep in mind what it'll do to their electric bill...

 

[bryanW1995]

he makes plenty of money so I'm not too concerned about the $10/month in electricity. however, the computer is his 6 year-old's gaming/internet rig so I'm probably better off keeping them on seti imho. I think I'll run this for the week combined with all 4 cores running seti and see how it looks. If it doesn't work out I'll look at taking a core off seti next week.

[bryanW1995]

I think that they're running a beta right now that is EXTREMELY time sensitive, as in 1-2 day max turnaround. They're giving 1.5x credit but you might end up with quite a few EUE's. Can't remember if I read that here or at the f@h site...

btw, big thanks to foxery for all the help yesterday!
