From http://foldingforum.org/viewtopic.php?f=66&t=18756, p6903 will soon be released to the beta team and will need at least 12 cores.
Just as I was about to sell the i5 2500k and get an i7 2600k to get some bigadv love going on Hope they don't can the 'normal' bigadv units completely.
Interesting. With no -bigadv WU for a few days, and these new units coming up, it could be time to play with the improved kernel or scheduler or whatever it is in Linux.
found this on evga forum about the new p6903: Base points: 30964 Deadline: 17 days Preferred deadline: 10.2 days k-factor: 26.86 apparently still subject to change but this is what it is currently stood at
After resolving post hols farm/network issues SR2 #1 just picked up one of these using the bigbeta flag. Early frames are averaging a tpf of 21m 16s for a theoretical ppd of 368K Looks like points inflation may have struck again.
Yep, crazy. The tpf seems to be holding steady although there's no telling if there'll be a points adjustment before general release or if there's any stability issues at high OCs .... early days.
So completing one of them WU's is going to net you about 500k credit! [Starts thinking about whether spending student loan on food/rent/alcohol is really worth it]
gonna try fishing for one of these monsters tomorrow when i get back to base. Using 980X at 4.1GHz with H70 cooling, might even give the graphics cards a rest for a while!
I am only achieving a tpf of 26m 15s with a dual X5650 SR2 with Ubuntu 10.10 ck. Air-cooled, I could only overclock to 3.75GHz. Are you doing some special or have you picked up a good p6903 work unit? I would need to overclock to 4.53 GHz to match your tpf.
Firstly, I didn't realise you had an SR2 so a belated welcome to the team club which I think is now up to 4 members I'm running a ck kernel on native ubuntu 10.10 with tear's kraken wrapper but I think the difference may be attributed to overclock and memory speed. SR #1 has watercooled 5680s running at almost 4.4GHz thanks to much WC advice from coolamasta. The bclk/multi is 191 x 23 with 2000MHz memory. I'm also running a pair of 5660s on Corsair H70s at 4.2GHz although I'll have to drop this as things are getting a bit toasty as we enter Summer. You really should be able to go higher than 3.75 with decent air cooling unless the rig's environment is working against you or you got really unlucky with the chips. Don't hesitate to shout if you want any help with tweaking. Last I saw coola was getting good OCs with quite low vcores.
Thanks. Oner of these days I will have another go. Maybe try to turn the coolers so they blow from one to the other towards the back instead of both upwards. However, the room is quite warm at the moment.
Preliminary numbers for -bigbeta Dual Xeon X5650 at 2.66GHz (stock), 12GB --> TPF 31:54, ETA 2.2 days, PPD ~200,000 980X at 4.0GHz, P6X58D, 6GB --> TPF 45:48, ETA 3.2 days, PPD ~ 116,000 Both an increase of about 80% of the PPD of 'ordinary -bigadv' on the same hardware, both running Project P6903 on Ubuntu 10.10 with BFS, both well within the preferred deadline of 10 days. TPF from HFM.NET, PPD estimate from here
Is the speed scale proportional per CPU on a 980x compared to a i7-920 at the same speed for folding? If a i7-920 @ 4ghz took 50% longer per fold (based on 8 cores vs 12) then the time per fold would be say 69 minutes, which with the points calculator would take 4 day 19hours @ 63000ppd a big increase. Which would also mean that the 2600k's running high clocks should do it also easily and quicker than the 920, unless they shorten the deadlines which could then put it back to a 6 core minimum. Have i got this right or am I looking at it wrong Maybe someone with a good 2600k overclock should give it a go and let us all know what time frame you can do it in.
i'm hoping to be able to get some of these after a minor upgrade on my pc later this week edit: anyone completed any of these units? if so how much did you get for them?
Ahhhh good stuff, sweet PPD there phoenicis!! Chap, with the -bigbeta flag do you need to be an official Beta tester with Stanford to run these or can anyone you the flag? I'm thinking about trying my luck out on my SR-2 and i7 970
anyone can run the -betateam / -bigbeta flags i'm running the -betateam [client-type: beta in v7] flag myself with no problems whether you're 'supposed to' or not is a different matter
little tip: HFM can work out the ppd/credit for you, Edit/preferences/web settings/project download URL .. enter http://fah-web.stanford.edu/psummaryC.html press OK, then tools/download projects from stanford.
was flicking around EOC and came across a user called SACO who in one update uploaded one WU which netted him just under 620k! would love to know what setup he is running!
