Quick question... hopefully

[Webby]

So I have been happily running F@H on my X1950xt all week and it chugs along giving me 330 points per work unit every 18 hours or so.

Now my question is would I generate more points running the SMP client on my E6550? Obviously nobody can say for sure but I don't want to waste valuable folding time trying it out if the is no way its going to compete with my GPU. I understand the points are good for SMP units but if it takes more than 4 days to complete a WU then i would think my GPU would be doing a better job, and my GPU can run all day every day apart from when I'm playing games if I was relying on my CPU then when working (general office stuff plus modelling software and photoshop etc) it may stop folding making it take even longer!

The other thing I could try would be running a CPU client on my second core (1 appears to be loaded for the GPU client) and I have no idea how many extra points this would generate anybody got any ideas? And how would I do this? Tried (not very hard) last week but it didn't like running 2 copies of F@H.

All help, comments and suggestions gratefully received!

this machine, a T7400 core 2 duo, manages 1 big SMP WU every 28.5 hours. each of those WUs is worth ~1700 points.

In that case I guess its probably worth a try to see what my E6550 can do Will set it up when the current WU on the GPU finishes at about 23:30 tonight no point in wasting the last 10 hours now is the!

Webby..... keep a tally of your results, as many people ask this

Thanks for your efforts too

Okay, the GPU client has stopped and the SMP client has started... so far 1% (5000 of 500000 steps) that first percent took 23 minutes extrapolating it should take 38 hours to complete the work unit. Now I know extrapolating from 1 point is pretty silly but its all I have so far! Will update again later with a better estimate hopefully!

But even at 38 hours as long as it provides more than 660 points it will be worth it!

big smp units should give you 1700 or so

but 38 hours? is windows really that much slower than linux?

IIRC - All units are not equal, sadly. Hence the differing points per unit.

Still, he has a faster CPU. It would need to be a beefy unit for that much of a difference.

Right so as promised its update time!!!!

So we have done 5% and here are the figures...

00:25 0 of 500000 steps 0%
00:48 5000 of 500000 steps 1% (23 mins)
01:18 10000 of 500000 steps 2% (30 mins)
01:38 15000 of 500000 steps 3% (20 mins)
01:58 20000 of 500000 steps 4% (20 mins)
02:18 25000 of 500000 steps 5% (20 mins)

So I'm guessing that maybe the first 2% go slower than the rest perhaps who knows! Anyway working on an average of 20 minutes per percent that totals 33.3 hours for the work unit a bit closer to directhex than the original estimate of 38 hours. I will update again in the morning if its changed significantly.

Edit - Okay so we have reached 44% after 14 hours which works out to be 31.8 hours for the work unit each percent is taking between 19 and 20 minutes, now all we have to do is wait and see how many points its worth!

Right so that is 1 SMP work unit down! Took a total of 31 hours and 22 minutes and I received 1760 points for it

So here is a quick run down of what I have achieved so far points/hour (pph)

GPU client running on a stock 2D speed x1950xt (GPU 500 / Mem 594) : ~18.3 pph
SMP client running on stock speed E6550 (2.33GHz) : ~56.2 pph

The only other things to try would be two instances of the CPU client (one per core) and the CPU client and the GPU client running concurrently. However I don't expect either of these to exceed the SMP client in pph terms. The CPU client I have running at work achieves 343 points per WU (doesnt run large WUs and still takes 4 days each...) so if this transferred to the E6550 it would need to complete 2 WUs (1 per core) every 12 hours to compete with the SMP client. Maybe I will experiment with these options later in the week for completenesses sake if nothing else!
