Cannot seem to get GPU tasks for Einstein

[DrPop]

Can anyone please decipher this for me? http://einstein.phys.uwm.edu//host_sched_logs/5444/5444535 Thanks! :o

I am able to get tons of CPU WUs on my rigs, but cannot get any GPU WUs to download after about 30+ hours of waiting and trying at different times, etc. This is happening on both ATI and CUDA rigs.
Some setting must be wrong, but I can't figure out what?:confused:

How about posting a picture of you project preferences page?

Hi Z, thanks for responding. My rigs are connected to the Hydra account - just the default setting.

Here is a similar error I am getting referred to on the rig with ATI GPUs: http://einstein.phys.uwm.edu//host_sched_logs/5444/5444532

[zombie67]

Seriously, a picture of the page please? No idea what "default settings" means.

Edit: Looks like the host with the first link posted, got some GPU tasks.

[DrPop]

I will get to it in a second here, sorry, I thought you had the login info for the Hydra, I guess not. Al McAdams PMed me - the CUDA problem was old driver - that is fixed. Tried to download and install the new ATI driver just in case same problem there, but that is strange...it all uninstalled and installed just fine - but it is still saying Catalyst 12.3 instead of 12.4??? I dunno. I've got a meeting I'm supposed to be at in 1/2 an hour, but I'll try to get it resolved here.
Thanks everyone.

Thanks for the picture. Everything looks good there.

In any case, it looks you are getting GPU tasks now. And yes, there are certain driver and BOINC client versions which are not allowed on Einstein. See here for more:

Ah, OK. So there must still be a driver conflict or something of that nature on Puma w/ the ATI cards. Cheetah, with the 2 CUDA cards is pulling WUs fine now, after I updated the nVidia driver like Al suggested. Guess it's time to put on the nerd hat and see what's up with the ATI rig...:-B Something is definitely weird though, because it appeared to uninstall 12.3 Catalyst drivers just fine...rebooted, and then installed 12.4...rebooted again, and then checked it - still says 12.3 Catalyst for some strange reason.:confused:

That's a known issue. 12.4 IS actually installed. AMD just forgot to update the version number in the registry. They say it will be fixed with the next release which, by the way, will no longer be monthly although they are keeping the YY.MM naming format.There's some patch somewhere you can try but I didn't figure it was worth it as the CAL and OpenCL driver versions prove it is actually 12.4 installed.

[DrPop]

Thanks, Slicker, that makes sense then. The thing I can't figure out though, is why the ATI rig can't pull GPU WUs. Got the CUDA WUs coming in fine now on the other rig...

Thanks team for this discussion, it helped me solve my own NVIDIA gpu problems.

However, none of my ATI cards are responding to Einstein workunits. Guess I have more work to do! :-B

To get Ati-work you'll need to run BOINC-client v7.0.27 or later, so I'll recommend to try v7.0.28 that is the current test-client.

Mine either and I am running 7.0.28.

Mine either and I am running 7.0.28.

I'm running 12.3 ccc, 7.0.28 on a single 6950 and I'm getting all the wus I can handle. Running 2 wus at a time. Very strange that others, running similar configurations can't get work.

Hmm, according to your host-info you're running driver v1.4.1664, now to find-out that this equals as Catalyst-version is difficult to find out to say the least...

... but, going by a win7-computer, this seems to be around 851.4, now this again isn't very informative, but this seems to be around Catalyst v11.5 - 11.6.

So, assuming haven't mixed-up the Catalyst-version, Einstein@home demands catalyst v12.x and not earlier versions.

The system-requirements is detailed in the 1st. post in the thread linked from the homepage, http://einstein.phys.uwm.edu/forum_thread.php?id=9445 and it says

Minimum Requirements:


• Windows or Linux

• BOINC Client 7.0.27 (download)
• ATI GPU or APU (OpenCL 1.1 compliant, equivalent to Radeon HD 5xxx)
• 512 MB video memory
• Catalyst Driver 12.x (don't install the APP SDK!)

AFAIK it doesn't matter if you've separately downloaded and installed the app sdk, but during installation of catalyst-drivers you do need to install the part (mis)-labeled as "sdk" or something, to get the OpenCL-support Einstein@home demands...

[Duke of Buckingham]

Well I have 2 computers running one is very ancient and has no usable GPU. This one I don't expect to run Einstein OPENCL. In fact this computer is not running the project at this moment.

The other runs POEM that has almost the same configuration. | have windows xp 64 with 7.0.28 Boinc version and 6.14.10.7256 catalyst 12.3. This one runs OpenCL for POEM why shouldn't it run for Einstein?

I understand the instructions of Einstein page, except for don't install app sdk. I made the basic instalation and don't know how to see if app sdk is installed or not. That is the only difficulty for me. All other conditions seem to be completly fullfill. Maybe the sdk is the problem, I don't know.

I am for this moment running POEM and Moo. So I am not very worried or in need to run Einstein at this moment. I was only saying that I have the same problem but I am very very very slow at GPU configurations. I have just started and don't know nothing about it. It was a big victory to put POEM running on my computer.

The link below shows the error that the computer SSFORCEUNIT2 encounters while trying to run ATI GPU workunits.

Looks like this may be the culprit. Requires a newer version of OpenCL support than is available in the card(?) So this is implying 4XXX cards may not be supported? Looks like OpenCL 1.1 wasn't supported until the 5xxx series cards?

Too old GPU...

You have to have a 5xxx card or above. I have 3-4850s in one rig that are all useless on Einstein.

If I recall, Einstein's CUDA apps required 1 CPU + 0.5 GPUs to run. GPU enabling certain algorithms is like putting a turbocharger on a moped. Sure it goes a little faster, but what's the point? But, when all you have is a hammer, everything looks like a nail.

If they wrote separate kernels so that they didn't use the OpenCL extensions for older hardware, the 48xx GPUs would still work. I've done it with Collatz knowing that AMD is slowly phasing out their CAL/Brook+ support and the Catalyst 12.4 driver on my 4830 works fine with OpenCL 1.0 apps. You just can't use texture memory, etc. because AMD didn't implement it in their earlier versions and then stopped supporting the 48xx GPUs before releasing a version which did support texture memory in OpenCL.

Note: CAL/Brook+ does support texture memory on HD 24xx and higher so it was a matter of porting vs the hardware not supporting it. They way they chose to implement it in OpenCL was not supported by the hardware because they implemented it a different way. Lazy programming if you ask me since they could have implemented both. But then, why would people upgrade to newer GPUs? It's all about marketing and the bottom line.
