Re: Good morning everyone

Good Morning All.
I got my Gold SCC but I have started up Open Zika again as my points haul from SCC seems pitiful. Dave's stats show that FAH is by far the largest point haul per hour run followed by OET and SCC (not counting HST as I can't get any WUs). According to my personal stats I am getting 107 points / h for SCC. 124 for Open Zika and 57 for FAH. Why the huge discrepancy? I still run for about 131 hours / 7 day period (power cuts permitting) but my points have plummeted. At least two of my MACs do little or nothing apart from crunch WCG. HELP

Re: Good morning everyone

@Thargor, Richard,

Sweet, it's funny how we all end up looking at similar stuff!

I've too been looking at the Engineering Sampe (ES) / Intel Confidential / Qualificatino Sample Xeons - my 2 cents for the benefit of others - you do have to be careful with them
(Intel Advice on ES chips )as they are still effectively Intel property and always will be, these have been issued to manufacturers and labs for testing, those ones are equivalent to very high chips (hence the price) but there's no guarantees of performance under 24hr 100% load, in theory they are worth $0 and have no guarantee but ... in practice they clearly have a market. Like everything on the market there's a sweet spot, from my limited research I'd say it's around the 2628L v4 up to 2650 v4 range there's a bunch of 12-16core chips in that space that retail (lets say retail even though you cant sell what you dont own) for around £110-£160, the MOBO's another £300 +DDR4 RAM which is a chunk too. You could put together a 48-64core low wattage (relative to the servers we've been discussing!) workstation for under £800.
Of course those non-retail chips are still an issue, I'd guess uncle Intel wouldn't mind if they were 100% dedicated to crunching and helping with medical and scientific research... in fact that's probably the best place for them. I fear a lot of them end up in workstations on EBay and no-one knows their provenance.

@Rod, my FAH stats were terrible too for a while so I actually switched away from it for a bit but I'm back on it now and need to check how mine is going. I guess it's working well for some people though as it looks very productive on Dave's stats site - 277/hr currently. Wondering if you have loads of them pending validation?

@Dave,
I've been reading your posts reduk and mac1 with some jealousy. I have a thinly populated four bedroom house, and a nice unheated utility room in which to tuck a non-silent crunching rig... no, no, get thee behind me Satan!!!

No excuses for you my son, get in there! 80 threads cool what can go wrong?! Of course you could get one of those Dual 2650's from where Richard got his, they do another model with a lid for a little more, it looks like it might have a PCI slot too.

cheers,
Andy

@Dave.. Your name is on this 256 (512 with HT) core monster: 16x HP ProLiant BL460c Gen8 C7000 Blade Center 32x Eight Core Xeon 2048GB RAM - http://www.ebay.co.uk/itm/401195610071
Only 6kw's at full load!!

@Thargor
Why go with a mere 20 cores, when you can have 24? biggrin

Once Trump drives down the dollar value, these e'll be cheap as chips laughing
Awesome power, double the floating point performance of the DL 580 g7 E7-4870 procs, let me know how you get on!! wink

Re: Good morning everyone

@Darkmatter.NI - You're smashing it at the moment, you seem to have trebled your points! biggrin Which project is working out for you, I'm wondering if it's FAH which Rod is seeing the opposite effect on ... or have you over-clocked like crazy?

Re: Good morning everyone

Morning... just moved my home 60kva backup generator from a box trailer in to the garage when it suddenly dawned on me that the only way into the garage to start it is through an electric garage door.. doh
@mac1.. here's my average points per project run time per day, FAH phase 2 doesn't appear very generous:
  • Smash Childhood Cancer - 4082
  • OpenZika - 3986
  • Help Stop TB - 3469
  • FightAIDS@Home - Phase 2 - 2735
  • Outsmart Ebola Together - 4367
  • Mapping Cancer Markers - 2966
  • FightAIDS@Home - 4624
<---- biggrin
@dcrobinson, thanks for the great stats btw
Seriously though, my stats website..

Re: Good morning everyone

Good morning all. No overnight improvement on the points front - all 3 macs are showing a nose dive in user average. The CPU time (~131 h for a 7 day average) has changed little. With SCC I seem to get low point counts except when the WUs enter and leave PV Jail when I always seem to get a 50% boost. Curious! I have run the CPU benchmark on all my machines and this is what I get.

27" iMac Intel i7 Quad 2.93 GHz 1967 FP MIPS 4304 Integer MIPS
17" MBP Intel i7 Dual 2.8 GHz 2994 FP MIPS 6586 Integer MIPS
15" MBP Intel i7 Quad 2.3 GHz 3319 FP MIPS 8534 Integer MIPS
All per CPU

Memory is correct speed for all. I don't understand why the 27" iMac has a faster processor but a much lower performance. Could it be purely temperature related? My CPUs run around 98 C on this one while they run at 83C on the 15"MBP and 104C on the 17" MBP

I have switched to FAH in order to get a Saphire badge, don't know when this project will end. Once I achieve that I will switch to SCC.
My points really have increased!

Re: Good morning everyone

Nice one DM, hope that continues.

@Reduk,
Thanks for the stats, I took a screen-dump of my project contributions a week ago so have created a sample from there and added Rod's in too.
reduk/Day    mac1/Day    rts48/Day    Project    reduk/hr    mac1/hr        rts48/hr
4082 5175 2568 SCC 170 216 107
3986 5554 2976 OZ 166 231 124
3469 3897 HSTB 145 162
2735 3534 FAH2 114 147
4367 5547 OET 182 231
2966 3570 MCM 124 149
4624 6687 1368 FAH 193 279 57

The behaviour looks very similar overall, which means that for the most part AMD and Intel chips don't have much preference over projects, I was kind of hoping we might see more variance so we could tune our projects accordingly but I guess this takes that decision away although there might be something in the OpenZika project though - thats slightly skewed, it shows up better in this graph (posted on that Noddy forum for ease).
Points Chart
I may also have bid devilish on a couple of things I don't really need earlier. That Belgian shop is great, thanks for the heads up on that - this forum's gonna cost us all a lot of money crying

@rts48
Those temps look very high, although i7's can run at that temp they might be throttling to protect themselves, I think it's this throttling that is also causing the spurious claimed/granted credit behaviour too. Check out that chart above, it shows your numbers are way off the pace, I'd expect modern I7 quads to be as good if not better than server chips which tend to favour lower ultimate speed but higher core counts and reliability, would need your chip model numbers to check this though - and the temps.
For reference my i7 3770 quad scores 4100FP and 11324 Integer MIPS.
A few years ago I let a core2quad Q6600 run for 3 months performing some machine learning analysis, when I finally checked the heat-sink it was absolutely clogged (Intel standard top mount) I mean the fan had compacted dust into the heat-sink and was now starting to fail itself, the poor set-up was more of an insulator for the CPU! Like yours it was running at 100deg C but after a good clean it went back to 60 even at 100% load and showed no ill effects - apart from a whining fan raised eyebrow. It might not be this but I'd recommend to check all the air ways in / out and of course the heat-sink, if you need to clean it, it's probably easier to take it off the mobo, best to use careful manual labour / pressurised cans of air to blow the dust out, vacuums are out due to static electricity build ups of course.
If the PC's get moved a lot there's a risk that the contact patch between the CPU case and the heat-sink may separate allowing air ingress this is more of a problem with laptops though as they flex more. I7's are allegedly made from the better part of the silicon so are more able to cope with higher temperatures so it might not be this but because your numbers don't align with the pattern and 100 deg is right at the operating limit I suspect throttling is playing a part.
When the CPU's cold it's setting good benchmarks which cannot be achieved when throttling starts, conversely when it's hot and throttling it's setting a very low performance expectation. WCG has some algorithm that detects spurious claims for points it's primarily to detect people gaming the system for additional points but in your case it's likely to be compensating - but with the CPU's running below par you're missing out on a bunch of crunching.
Hope something in that text blob helps but keep us posted.

cheers,
