1. your motherboard is an motherboard with an AMD Chipset(https://www.megamobile.be/productinfo/103151/Moederborden/MSI_K9A2_Platinum_-4x_PCI_Express_x16,_AMD%C2%AE_CrossF/) that means it only has ATI's crossfire X so you use only the first gfx card lolzor

2. NVIDIA has only triple-way SLI not Quad-way SLI

conclusion: I think you're a kind of a show off that just wasted some money ;)

as for 1. For GPUGRID SLI has to be disabled, so it also works on crossfire boards. 4 PCI-e = 4 cards that will be used, not only the first one. Do you really think the GPUGRID team built a machine with 4 graphics cards and they wouldn't know if only one card would be used?

as for 2. See point 1. SLI has to be disabled, so it doesn't matter if it is a SLI or crossfire board and if it is triple-, quad- or octa-way. ;-)

conclusion: Sorry but you obviously don't know what youre talking about... The next time do a little bit more research before posting things like this. ;-)

Totally off topic but instead of pimping its hardware maybe gpugrid could get itself some reliable hardware that is actually up five 9s and has workunits available occasionally. As it is I am about to go back to Folding@Home with my ps3 and say heck with the boinc credits. I would rather the machine contributes to science instead of sitting there as a paper weight.

Five 9's?

Their hardware wasn't at fault; they lost power over a holiday weekend when nobody was around.

Have you ever built a datacenter with that kind of reliability? Or rented space in a hosting facility that provides that kind of reliability?

I have.

It's horrendously expensive, but it's necessary for some applications such as financial services (can't have the stock markets going down every time there's a glitch, can we?).

It's not just having reliable hardware. No hardware is perfect. So your software and network need to be designed to continue operating regardless of any single failure, which means having redundant everything -- multiple phone companies, UPS and generator power, geographically diverse locations for your redundant datacenters, etc.

As annoying as it is, outages such as this are merely an inconvenience, and building up a high-availability system to run a BOINC project would be an incredible *RECURRING* waste of money that could be better spent elsewhere. There's no reason why a system like this needs that kind of resiliency.

That being said, I don't mean to imply that their system couldn't be more resilient than it is today. But we don't have a lot of facts about what happened over the weekend, other than it being due to a power outage. If it was a short power outage and they don't have UPS, then, yes, we can fault them for not having UPS. But if it was an extended power outage, even a large and obscenely expensive UPS wouldn't be sufficient, and backup generator power would have been required to keep the system running. Cost aside, in some locations a generator isn't even an option.

As it is I am about to go back to Folding@Home with my ps3 and say heck with the boinc credits. I would rather the machine contributes to science instead of sitting there as a paper weight.

To add to what Michael G. said ...

In many cases large organizations schedule power outages over holiday weekends because it impacts the fewest number of people and projects on going in the affected buildings. We saw this outage because power went out on the server systems we depend upon.

That said, even Einstein that has something along the lines you suggest has been experencing outages too. And they have systems distributed across multiple locations and they could not stay on the air ... and I am not sure they are out of the woods yet.

But that is the point of BOINC, at least in theory, while GPU Grid was out we would have just worked for other projects. The problem is that GPU computing is new to the BOINC world so there were not many places to go to get work. I went onto SaH Beta and did about 50-70 K worth of work for them ... and on one system until I can saturate it back with GPU Grid work I will feed it the last of those tasks ...

I agree about costs and was being melodramatic. The reputation though of this project on the internet is that it does not reliably feed work units to speciality computing devices such as the ps3 as compared to folding@home. Some of that I am sure is due to a large difference in funding and priorities. I am hoping this will change as to be honest not only do I prefer BOINC credits but I have the machine at remote location I only visit several times a year and couldn't change it even if I wanted for some time. I was smart enough to do backup work on yoyo but again lets be honest and say neither yoyo or seti is doing the kind of work that is as critical as gpugrid and folding@home. Another worthwhile boinc project like rosetta or einstein needs to harness the power of the ps3s and then this becomes a non issue.

Einstein is working on a new application for CUDA and possibly OpenCL as is MW ... The Lattice Project just ran a short test of the Garli application on CUDA (with about 5-10% or the tasks hanging as does the CPU application which as I read the project's posts they find "acceptable" and I find abhorrent, I guess it depends on how much you dislike waste).

There are a couple other projects in the wings with rumors ...

But this is still early days and to be honest *I* think that progress is about as fast as one could expect. Sadly, this still leads us to be in the position where we are lacking in choice for the moment. Of course, if you have an ATI card you have even less choice ... but ... soon enough we should see another project on-line ...

Of course, if it HAD been Einstein, we still would have been SOL too because they had an outage this weekend too ...

Nice discussion, but please do not totally forget the thread topic.. this is a sticky, after all.

awesome system can just imagine how much work that thing is doing whew...

it must be really hot in whatever room that system is in if its on 24/7 :)

thats a Silverstone TJ07 btw... http://silverstonetek.com/products/p_contents.php?pno=tj07&area=usa

im getting that case for a summer watercooling project.... you should consider watercooling that system and overclocking... its a really nice case to watercool with

att:cencirly Do You Mean That....
Wauiie',What a machine Igot A' ASUS,H78D-HDMI-790 Board W/the DVI Plug,and ,a
AMD'9950'4Core'.I Put The,Thing in,My Machine And The Stuff first dident,
Work,well i,found out that it,needed to have the 8pin,plug'on it again,
It's,in an,900case.and the one w/we are sorry that and blablablabla,but a blower is but you find it,we are sure,on it,cincirly ants,,on the run......
well the 8pin on,and were ave a lift off'.
only one time8800-Glacier BetaVersion,W/512mb-768Mb.and 6pin on.no DVI But
A,A-to-B Plug,then i started it again,now it got weired,it now first at this point after 3-5 runs' presented me w/a Screen W/the HDMI-Wifii-and so on
Then it,blinkd'blue,and a,grey screen ran down ,then it dident started any
Aain,What is the matter w/that machine,A,HKM 630Watt 2x160b,Sata.2xDVD-Cd
From,sata to. samsung,504-and the 2012.W/the softwarer from,Nero Softwarer.inc.
it now dont play,DvD's with my old costelation,on, an,ASUS-M3H,Sli-Hdmi deluxe.its quite an horribel,state im in,i got seconds then it'gotta go on,the techbed'to be upgraded once and for all,ps,this lap top is my only net chance i have when i wisiting one i,girl i know,i hope one with such a,monster knows any thing about my troubels,

Would you mind using english sentences? That would help a lot in trying to understand what you want to say.

The technical specifications for this machine are the following:

Motherboard:
MSI K9A2 Platinum / AMD 790 FX 4xPCI-E 16x
CPU:
9950 AMD Phenom X4 2.60Ghz, RAM 4Gb.
GPUs:
4x NVIDIA GTX 280
Power supply:
Thermaltake Toughpower 1500W, with 4 PCI-E 8-pin and 4 PCI-E 6 pin power cables.
Box:
Antec Gamer Twelve Hundred Ultimate Gamer Case. (Ours is a Silvestone but it is more expensive).
(The computer case is quite important. There are other available, but not all fit the purpose as you need to have enough cooling and free space after the 7th PCI slot to fit a dual slot graphics card as the GTX280.)

In the future (during 2009) we may be able to use multiple GPUs for one WU which will be rewarded higher.

New GTX290 cards should be coming out soon.

Old bones I know, but did you ever make any progress into running one task on 4 cards?

Thanks,

PS. I'm still using that same K9A2 Platinum Motherboard.

It is working locally, but not for GPUGRID yet.

gdf

It might allow for some faster task turn around.
