6 WU Per core? Why not per GPU?

I put the ATI HD Radeon 4870 X 2 in a single CPU core system just to run the GPU work. I have another ATI HD Radeon 4870 (Single) to put in a system. Maybe I should think hard about what to put it in now.

I still think it is a shame to waste available resources.

And to add to the GPU list, the 5830 is missing. Unless what I've read is wrong on it doesn't support double precision FP calculations?


It does support double precision, the list has just not been updated in a long time.


Good to know for sure. Thinking of getting one though more for gaming than crunching. If I were buying for crunching I think I'd go NV again since CUDA is more widely used. But I've always liked the ATI drivers better :)


CUDA might be more widely used, but the ATI cards are thrashing them in the WU completion category.

The top 200 hosts all run ATI cards here, pretty much the same thing at Collatz.

GTX 480 is taking about 200 seconds more than a 5870 and about 100 seconds more than my 5830.

True the ATI cards are faster in the projects they are used in, but this is the only project that I crunch that supports ATI cards currently.

So I say NV for crunching (For myself at least) as it allows me to run more projects on my GPU as of right now. Hopefully OpenCL will change that at some point though!

Message 40295 - Posted: 9 Jun 2010, 11:47:42 UTC

I've just acquired an s/h pc with a PCI 16 express slot, but due to it being a small form factor case, standard length/height cards wont fit. Are there any double precision half height cards out there that could be used to crunch MW? I can get an HD4550 but I think its only single precision.

Thanks

If you leave thee side off the case, can you get the full height HD4870 card in?

No John, its too long as well. Also I cant update the psu as a standard one wont fit. I might put it to one side till single precision projects come out.

Message 40705 - Posted: 27 Jun 2010, 15:10:32 UTC

Has anyone used the ATI HD 4850 card on MW?
That seems the lowest priced double percision card that ATI
has that will work with MW. The 4770 seems to be costing more and
has 640 streams to the 4850's 800 streams.

I am looking for the lowest costing ATI card for GPU.
4670 is the lowest costing I would buy, but it does not work
with MW. So if I about double the cost to $100, then I can
go to 4850 card.

My GT220 card died a few weeks ago, so I was looking at getting a replacement
and for Collatz, ATI was the only choice for the price. I can get over 4 times
the credits going ATI for the same price as the GT220, so now I am looking for
the lowest costing ATI that works with the most projects.

I am running an AMD Phenom 9650 quad core @ 2.3 GHz, with only 1 PCIe x16 slot.
It does have the smaller x1 slot though. I have 4 gig ram and 1 TB internal and 1TB external. I run Ubuntu 64-bit Linux. I could run 64-bit XP, but need the free DVD authoring and video editing software, since on a fixed income I cannot afford the software prices. That is why Ubuntu Linux.

I am not a gamer and run GPU only for BOINC. My monitor max out at
1368 x 768 as a widescreen 16:9 monitor. I would love a bigger one, but
that was all I had the money for. I am really limited with spare money to
buy computer parts and such, so I need to get the best items for the lowest
prices I can. $100 is the most I can spare each month for non monthly bills
or food. Very limited.


ALSO
for anyone who is a programmer of C++ on Linux, please tell me what
is the easiest C++ system on Debian/Ubuntu to learn and use. Also
If there is an easier programming system, I would like to know. I
wish to relearn programming skills after 2 strokes took much of it away.
I used Pascal more than C/C++, but want to learn the easiest, most
powerful language "system" I can find "FREE". I miss creating things
like Mainframe Accounting systems and dedicated language editor, like I
did for RPG, all those years ago before I went PC only. Now I just want
to relearn it for my own fun, since it was fun for me or I would not
have become a programmer all those years ago.

Let me know OFF the lists at seti "at" krackedpress "dot" com.

Has anyone used the ATI HD 4850 card on MW?



Yup, using one now. this computer has one in it. Have a couple others, too, but they're shut down now to save on electric bills.

You should be able to do about 75k daily with a 4850, I got about 60k when I was using a 4830 on MW.

If you have an AGP graphics slot PC, then a Radeon HD3850 AGP will also do double precision. This card will give an output of about 25K to 30K.

Not from what I read, it will use the Juniper cores which are in the 57xx series.

The 57xx does not do double precision.

Hi,

if somebody has the feeling that his system is a bit too slow, try this:

ARES/2DIS/4GD5
intel centrino2
Limited Edition , Unlimited Power

- Dual Radeon HD 5870 with 4GB GDDR5
- Performance King~~32% faster than generic Radeon HD 5970

Happy crunching!

Does the new Geforce 460 do double precision? What kind of performance should I expect from it?]

Yes it does, but there is not currently a fermi app for Milky way so you will need to wait a little while..

AFAIK they are working on one..

This http://koschmider.de/pics/desktop_chips.png is a link from the GPUGRID forum.
It gives you an impression what you can expect.

"Yes it does, but there is not currently a fermi app for Milky way so you will need to wait a little while.."

So there is no way to tell the app that it's an older card and force it to work like the ATI 58XX cards, like you can with Seti@Home?

BTW, thanks to all for the prompt answers.
