Message 41129 - Posted: 30 Sep 2011 | 9:25:51 UTC

I'd like to see more work for ATI cards; currently the only PrimeGrid ATI app is obviously PPS Sieve. It's probably been said before, but there are a lot of us out here who would like to use our cards to crunch whatever the mods/organisers can, or want to, make ATI compatible. If seiving is the only viable type of task to port relatively easily then fair enough, but surely someone can try to do it with the TRP or CW sieve? I notice CUDA betas are now popping up for various things, but that leaves us ATI/AMD users unable to use our GPUs for those tasks.

If I was a programmer then I'd try, unfortunately I'm not. I think a lot of ATI/AMD GPU users would appreciate it if somebody who possibly could do it, might try if they have the spare time though. Thanks.

The ATI was programmed by a volunteer. If a volunteer wanted to try and program others, I am sure the project would take those for testing, but until someone who has the knowledge, time, etc. comes up to the plate you have what you have.

Yeah I know, I was only asking. If you don't ask, you don't get - I thought it might be good to publicly say that there is some "demand" (or request, I don't mean that to sound rude) for it.

I didn't expect people with 4 PCs and an Nvidia card on the project to care much ;), just saying that more apps for more things means more crunching, and I would personally like to see more than 1 app for ATI/AMD cards if anyone with the know-how is kind enough to do it.

Two of my machines have ATI cards. They just are not crunching here at the moment. So I keep track of the ATI work, also.

Heh, I had to get a little dig and a smiley face in there when I saw you had an Nvidia card, sorry. Let's hope we can both get our ATI cards crunching more in the future.

I myself am also an AMD fan and have some powerful AMD cards going to "Waste" in terms of prime grid.

I've always wanted to get into some GPU programming and have thought about looking into getting into this stuff, but sadly time has always been my limiting factor. I know no previous experience working with CUDA, OpenGL, OpenCL, etc. but plenty of experience across the board on all other platforms and architectures.

I'm curious who previously did do work on the PPS Sieve for ATI/AMD. If there is enough interest out there, and maybe even a group of people either with the experience, knowledge, or will to learn, maybe we can actually organize a group to work on some new programs.

I know I'd def. be willing to contribute my spare time to making it happen. Just, definately not a solo person job. :-)

The problem is that ati is the new kid on the block into the gpu processing
That gipsel find a way to use the ati cards for milkyway and made that project very succesfull seems to be forgotten by the people at that project.

Ati never had the resources to step on to this, and it costs a lot of time and effort to get ati's cards to work on jobs.

As i understand from the gpu guru's the language for ati cards lacks lots of common commands and functions which are normal for the nvidia counterpart

CAL is a very simple language so it can do very simple tasks, but when it does them it is super fast.
OPENCL/GL are for amd the only options to bet on since they lack the funds to develop their own processing language, i am not sure if they will get one like cuda but from what i see its not going to happen.

Only seti beta has at the moment some wizards who put alot of time into getting that to work for both the platforms. They are pioniers into this and maybe could give tips on how to proceed. And i am certain crunch3r would give advise if asked as well. But to get this going indeed some advanced knowledge into the matter is needed to get a working design.
And in the begin will be much slower then what people expect to see with the competing cuda language
As i was reading the threads on this only ati project i only see some volunteers made it happen, the same is happening now with llrcuda

I think Milkyway requires a double-precision FPU ATI/AMD card, because I tried to use my HD 6670 with it and couldn't, because of that. Not many ATI/AMD cards have a double-precision FPU, only the very high-end ones. Mine is a Sapphire overclocked one to 900mhz and the GDDR5 at 1150mhz, but obviously if it's not a double-precision card, it won't play ball. It's a shame because clearly my card is hardly slow at crunching, and it can do it at the same time as my 4 CPU cores with only a slight performance hit. I could leave my 6670 crunching all day really, it's fanless and got a TDP of 66w. I'd love a TRP or SoB app for it to munch at.

I think all LLR-apps need a double precision card.

I think Milkyway requires a double-precision FPU ATI/AMD card, because I tried to use my HD 6670 with it and couldn't, because of that. Not many ATI/AMD cards have a double-precision FPU, only the very high-end ones. Mine is a Sapphire overclocked one to 900mhz and the GDDR5 at 1150mhz, but obviously if it's not a double-precision card, it won't play ball. It's a shame because clearly my card is hardly slow at crunching, and it can do it at the same time as my 4 CPU cores with only a slight performance hit. I could leave my 6670 crunching all day really, it's fanless and got a TDP of 66w. I'd love a TRP or SoB app for it to munch at.


Indeed milkyway and primegrid need double precision
Which cards have double precision thats a different matter there are much more cards who can do DP but for some weird reason amd change the newer models cards to not have them except the top models.

As any 4770, 4830,4850,4870, 4870x2, 5830 5850 and 5870 have them, you see the oddity here even low models had DP.
when the 5xxx series entered the arena they took DP of the low/mid range cards

My 4770 runs milkyway just fine, although not so quick but for such low model it fairly runs them fast enough for me with low electricity use.

Well i believe you about these cards but if it should have got DP it would have heated up alot more then it can now :D
At present i am pushing my collatz towards my goal of 50m credits so it runs about 70c but if i switch it to milkyway the temp runs 11c higher at 81c
Even though many ppl say otherwise all my amd card who i had run fairly silent and for the work they do also kinda cool
The 5870 which runs overclocked hits 84c with the fan on 33% and can not hear him buzz, ofcourse i can crank up the fan but there is no need.
When i do switch on this card to milkyway the fan starts to blow faster and the temp goes up to 86c and at that moment it a little bit audible.

For the record, I just have an old Dell and shoved a silent 6670 in there - you could probably boil an egg on the heatsink:





I love it, the PSU is rated at 300w max.

As any 4770, 4830,4850,4870, 4870x2, 5830 5850 and 5870 have them, you see the oddity here even low models had DP.
when the 5xxx series entered the arena they took DP of the low/mid range cards

As you can see by your listing above, AMD kept DP on the whole 58xx line just as on the 48xx line. The 4770 was a special case as it was their testbed for the 40nm process and thus contained their full spectrum of technology. They decided not to include DP in the later 5770 in order to make the chip smaller and more affordable.
