I still have a 'JUNIPER' or HD5770, which is a Single Precision GPU.
Excellent and fast card, not to be used in Milkyway, but Collatz C. or SETI (Bêta),
etc.
A few days ago, I started gettin new work, which goes amazingly fast, every 1 to 2 minutes 2 WUs, are finished and UPloaded and another 2 are downloaded.
And maybe this Double Precision and High Load, 99% drives those 5870s
to its edge, the whole system, with an I7-2600 CPU (HT=ON), heats up the room with
550W/hour. (Even an AC is needed, 3 QUADs and 480; 470 and GTS250 GPUs).

But 'one has to have something to do' , besides work, living a life, etc., etc.
(Why am I telling this?). ;-)

And about using an app_info.xml file, can be usefull, if you want to run run 2
WUs on each card, but check if it works OK and give more efficiency by doing 2, in
less then double time, when doing 1!
[color=green]
<coproc>
<type>ATI</type>
<count>1</count>(0.5)(0.33)
</coproc>
<cmdline>1(2)(3) instances_per_device</cmdline>
[/color[

(I used to run 3 SETI MB WUs on my GTX480 and X9650CPU, no problems!)(Only heat)

Only, no typos in these app_info.xml file, all stated in this file, has to be
present or, it starts raining errors...........(I once saw about a thousand WUs dissapear
cause of such an error, tried to run 2 Einstein WU for GPU per GPU.
One typo...........error...........

Now only 1 per GPU, sometimes, I do turn GPU; Voltage and frequency down, Memory only lower frequency, or an auxillary or regular "office" Fan, wirh 1 side of the case is open.

Knight Who says Ni

Why does that document, "AMD_APP_SDK_Getting_Started_Guide_v2.4" say that the ATI FirePro V5800 card supports double-precision if it doesn't?

Another mistake: the HD4770 is listed as not supporting DP but it certainly does and runs MW at about 1/2 the speed of an HD5850, not bad since it also uses about 1/2 the power.

Thanks FruehwF for clarifying that.

I had no problem using my Q6600 cpu an ATI HD4380 here with Win7.
Now that I am using Ubuntu 11.10 the GPU does nothing.
Is there something I need to do in addition to running bonic and adding Milkyway as a project?

(I hope this is posted to the correct place.)

Thanks

I doubt if standard Ubuntu installations include the driver that BOINC needs to make that card usable, so check the BOINC log file to see if it even recognized the presence of that card. Scroll to about a dozen lines from the top and see if a line near the CPU description offers a a GPU description as well.

Mention what driver version number is shown, if any; some versions can cause problems.

Also check if your preferences for BOINC tell it that it's allowed to use ATI GPUs - if not, it will ignore the card.

The Einstein@Home project is also astronomy-related and does not require the hardware double precision support that Milkyway@Home requires, so you might want to try running a few GPU workunits for them (to avoid confusion, do this with all types of their CPU workunits disabled).

http://einstein.phys.uwm.edu/

If none of those help, you'll have to wait for someone more familiar with Ubuntu to offer more help.

As far as my knowledge Einstein@Home does not support ATI cards

I just checked, and you're right; they don't.

PrimeGrid does, however, for one of their sieve applications, so they should be adequate for a test of whether the board will even work under BOINC.

http://www.primegrid.com/

Thanks for the help. You are right, Ubuntu doesn't even see my ATI card.
I'll do some more research on that.

Primegrids PPSsieve on ATI/AMD-GPUs uses OpenCL. You need to install either the APP-driver or the Stream-SDK.
OpenCL for the entire HD4000 series is marked as Beta and be aware, OpenCL is like Java. Runs on many platforms but fast is different...

As rroonnaalldd says - Milkyway is best with ATI/AMD GPUs, PrimeGrid (the PPSsieving) is best with nVidia GeForce GPUs.

The latter can crunch using PCI (not express) 9500GTs OK, even if these are a bit slow now. These used to give an individual GPU RAC of 30,000, but this will now top out at 20,000. But the normal PCI expansion slots (4) should give an output just under 100K with a P3 rig.

Go away, I was asleep

Ok, i have a AMD Radeon HD 6570M/5700 Series(Dell). Why am i not getting any GPU WU's? I am getting WU's from other projects. Any cure for it?

The M series processors are not capable of the double precision needed to crunch separation work units, despite the similarity in names to the cards which can.

Thank you very much. So, the problem remains. Its a shame honestly, i don't want to do prime because i don't think encryption tables help humanity. Oh well, its a tie.

You may want to consider Einstein@Home, then, which is at least related to astronomy:

http://einstein.phys.uwm.edu/

Or, if you prefer, watch for Poem@Home to start offering GPU workunits related to protein research, and therefore with some connection to medical research:

http://boinc.fzk.de/poem/

Question for you - where do I get the info-app.xml file for milkyway?

I have one for Seti, but pretty sure it won't be something I can just copy over....

On Seti, I used it to set my GPU to .5, so I can process two tasks on the GPU at a time - can I do that for milkyway as well?

Genuine Intel Intel(R) Core(TM) i7 CPU 960 @ 3.20GHz [Family 6 Model 26 Stepping 5](8 processors
NVIDIA GeForce GTX 460 SE (1024MB) driver: 2856

Wikipedia says this is a compute number of 2.1, so I assume it will work.

Thank you very much. So, the problem remains. Its a shame honestly, i don't want to do prime because i don't think encryption tables help humanity. Oh well, its a tie.

World Community Grid has now announced that they will start offering GPU workunits "soon", but for one subproject only. Apparantly not soon enough to mention when "soon" is, though. New subprojects and new application versions usually show up on their Beta Testing subproject first (the one they make hard to find), then later go on to some other subproject.

I recently joined the Milkyway@Home Project and the system reports I have the following GPU:

AMD ATI Radeon HD 4350/4550 (R710) (1024MB) driver: 1.4.1385

I do not see it in the list of ATI Radeon models suitable for double-precision math.

Does this mean I am unable to participate in this project and as such should I remove it from my computer? I certainly don't want to continue to receive and attempt to process tasks if it isn't providing the accuracy required by the project.

simply as you can see from the task you're processing, you're doing your jobs on the cpu. In particular, you're doing jobs not solvable by the gpu at the moment, so don't worry, you're not wasting your time here!

Hi Peter, ideally set your preferences to:

Run only the selected applications:
MilkyWay@Home: no
MilkyWay@Home N-Body Simulation: yes

You can also set the following if you like:

Use CPU, Enforced by version 6.10+: yes
Use AMD (ATI) GPU, Enforced by version 6.10+: no
Use NVIDIA GPU, Enforced by version 6.10+: no

That way you'll only be doing the WUs that GPUs are unable to run.
Your GPU will work fine at Collatz, just set your preferences there to use only the GPU.

Peter, it should also work fine on PrimeGrid. Personally, I prefer finding prime numbers to working on the Collatz problem - I know of more uses for prime numbers that any results from the Collatz problem.

You may also want to look at POEM@Home; their protein work is related to medical research enough that I give them computer time also. They are already using some of the cards in the HD xxxx series, and would like to try on more to help them develop a list of which of them are suitable.


Something else for the rest of this thread: My desktop with the GT 440 occasionally gives me Milkyway@Home messages saying that I do not have the necessary double precision. Since the GT 440 uses a Fermi chip, I thought it had double precision built in. Could the developers check why I get such a message anyway, and either eliminate that message or make it clearer just what is missing?

64-bit Windows 7 Professional SP1
16 GB memory
GT 440 graphics board, 285.62 driver
i7-2600 CPU
BOINC 7.0.3


On another item for this thread: The AMD HD 7970 became available in the last few weeks, and the HD 7950 is expected to become available around the end of this month. Any word yet on whether they will work for Milkyway@Home? Any word on the board length and the power requirements (about the most important factors in whether I'll get one)? One BOINC project has already mentioned that they know it works on some other projects, but will need some changes in their application to work under their project.

GPUGRID has announced that that the HD 7xxx series of boards are the first AMD/ATI boards with enough of the right architectural features that they might be able to use them. So expect some competition for BOINC use of those boards, although not immediately.
