You shouldn't feel bad Cob. I believe 2bullish is running 2 or 3 high-spec machines. You can't expect to beat that with just one quaddie.

Thats true but unfortunately the vista machine spews out EUE's more than not and for some reason two of the quads both got stuck on MPI after fininshing the units for 24 hours then when they were both rebooted they EUE also, so that wa about 10,000 points lost all together.

I should be running at around 7000 ppd but I have nothing but problems with win SMP, ah well it is beta i suppose. Still have another quad and a 6600 at 3.4 thats not running f@h yet, when i get round to it I'll add those to my farm.

Thanks for the news Rich and a warm welcome to all new members.

I'm quite pleased with my progress considering what im running. Fingers crossed the Quad Core option for my Media Centre/Light gaming should help raise this... then its time to consider getting round to building my server :o

Without wanting to sound dappy, how come some people seem to have MILLLLLIONS of points for very few WU's..

Full House! How much do I win? :D

you win a fine pair of lollerskates :D



Well my first welcome back horrid SMP unit just uploaded and I got a far nicer one in it's place, around about 900PPD so hopefully I'll at least be in the top 50 crunchers next week :)

Time to chase me down a KE1HA! :D

You could go the VMWare/Linux route. It is really easy to do and my guide shows you how to do it step by step.

On that note I will finish work on the site tomorrow. I could do it now but I want to enjoy my Saturday off. :)

using linux in VMWARE gives better PPD?

Generally better than the WinSMP client due to the fact that a lot of the WinSMP WUs are benchmarked a bit lower (if you have loads of cache they're not as bad). Linux in VMWare is obviously not as good as native linux but it depends if you still really need Windows for some things (or you're just a bit scared :p)

edit: Reading again I think the comment was more about the linux SMP client behaving itself a bit better than the Win SMP client. The WinSMP client shouldn't be possible but they use magical localhost gnomes to feed the flux capacitors :D
If less WUs end up EUEing then you'll effectively get a higher PPD

rich99million and other X2 3800+ owners, what kind of performance are you getting with your systems with the SMP client? At stock is it fast enough to complete all Linux WUs in time? I just did something ridiculous and bought a 35W one for a set-top box I'm building so I figure I shall have to fold on it to make it worth the extra $35 I spent on it versus a 65W Sempron at 1.6 Ghz. :o

It shall be running Linux and will do no encoding, just decoding MPEG2 which, thanks to XvMC, should mostly be handled by the nVidia graphics chipset.

A stock X2 3800+ should be able to reach the SMP deadlines. When my X2 4400+ was crunching two SMP WUs at a time it managed to reach them.

I haven't run the Linux client for quite some time but I'm sure that my X2 overclocked to 2.4GHz was managing them in about half the final deadline time - at stock that shouldn't be a problem. Also the fact it's native linux should help as mine was via VMware.


My worst WU with WinSMP is p2610 which takes 2.8 days with a deadline of only 4 days - if those types of WU are around in linux (which I don't think there are unless you have a quad-core) then they could be a bit tight at stock and fairly heavy use of the machine for other tasks.

I've got them in Linux on dual-core, p2609 IIRC. They're a bit of a pain on C2D with 2MB cache and I imagine X2s could find them difficult.
 
Thanks again for the news, Rich! Team ms9cw just managing to hold off Gazzza to pinch the top place in the crunchers league. :)

Welcome to all new folders and welcome back to returning folders. Fold on Team 10!

ahh so they've got to linux :(

I'd be pretty miffed if I sorted out dual boot and still got saddled with one of those :o

2609 is one of the promiscuous WUs that works in both Windows and Linux. ~1500PPD on a stock E6600, ~1000PPD (WinSMP or Ubuntu under VMware) on a stock E6400.

Oh my days, just lost a 1760 on 92 %

Aaaaaaaaaaaarrrrrrrrrrrrrrrrrrrrgggggggggggghhhhhhhhhhhhhhhhh

nightmare - make sure that your not crunching the exact same WU again.
[16:02:30] Project: 2610 (Run 0, Clone 934, Gen 32)

if so delete it with a delete xx flag - one wu dieing at 92% is a pain but two is very **$£*%$$
 
Here's some of my winSMP benchmarks;

2605
Avg. Time / Frame : 21mn 20s - 1188.00 ppd
2608
Avg. Time / Frame : 18mn 18s - 1089.84 ppd
2610
Avg. Time / Frame : 17mn 01s - 1288.81 ppd



2651
Avg. Time / Frame : 19mn 11s - 1321.15 ppd
2652
Avg. Time / Frame : 16mn 46s - 985.96 ppd
2653
Avg. Time / Frame : 19mn 26s - 1304.15 ppd


It only seems to be 2652's that are sub 1k ppd for me, although it may have been skewed by workload at the time.

So far 9/9 WU's successfully crunched, avg 1.4 days per WU.
