I opened yesterday a new thread and I can't find it now. Sorry if i'm duplicating it.

This is my system http://setiathome.berkeley.edu/show_host_detail.php?hostid=7622568

And I'm afraid I need tune something to get performance from my GPU because WUs spends lots of time running, but use very few GPU running time.

Please can anyone give me a tip about ATI GPUs tunning.

Regards,
Raúl.

since you only have 2 posts it was easy to look through all of your posts to find your first message. Which you can find my looking at your Account info.

Since there are no completed tasks on your machines for us to inspect only general advise can be given.

Which Catalyst release are you using? I'm using 14.9 on my mobile Cedar, but I have not seen any significant improvements with drivers.

I can see you only have a dual core CPU running Windows 10.
So i expect Cat 15.x

Make sure to free 1 CPU core.

Hi,

yes, Catalist driver is 15.7

Here you have more details...

I'm sorry, I'm not able to link the image properly.


By the way, Mike, why do you recommend me to be sure to free one CPU core?

I believe the recommendation originates from the app developer. However it might have been from those that did initial app testing. With OpenCL apps CPU resources are required.

I too have been tuning my AMD cards. Two R9 280Xs. My discussion was under the thread; AMD CPU Tips. There is some really good info there including some MS hot fixes for particular AMD processors. Most of the discussion has been over the last week, so you shouldn't have to dig too far. As far as drivers, I'm staying with 14.X also. 15.X seems a bit troublesome still.

Good luck and happy crunching.

If the OpenCL app doesn`t get enough CPU ressources it won`t feed the GPU properly and simply wait until it happens.

Thank you all for your help.

Louis Loria II, the thread is very interesting, but I was not able to find anything of worth to solve my particular problem.

Mike, I had change the settings and dedicated 1 CPU to feed GPU, apparently nothing happend, now it's after 92 GPU hours and estimated time to finish is 338 hours. I'm afraid this is not the solution to the problem or I made a mistake...

Check system event log for driver restart event.

As far as i see, his computer has 1 GB RAM. Think, the computer is nearly 100 % busy with swapping.

- Performance is not a simple linear function of the number of CPUs you throw at the problem. -

I'd expect trying to do anything on the system would be painful.
The recommended minimum for Win10 is 1GB for a 32bit OS, and 2GB for the 64bit OS.
Given those are the minimum recommended specs, the realistic minimum you'd want for general use would be 2GB for 32bit & 4GB for 64bit systems IMHO.
Also given the system is a P4, I'd suggest not using the CPU at all for crunching- leave it all to the video card.
The P4 would use a lot of power for doing very little work.

Yes, 2 x 1GiB graphics cards is expected to be problematic on modern Windows (especially 32 bit variant), where there is only 1GiB system memory installed. I would start by pulling one GPU, and preferably add more system RAM. Alternatively switching to 64 bit and piling on much more system RAM would probably make both GPUs usable again. Win10 of course has some unknowns, but IMO that system is under enough pressure that no amount of trying to get around adding more memory and allowing for 2 cards will make it work well as is.

Ok, thank you all for your comments.

The system is an old system fully dedicated to boinc projects. I had several problems to use the ATI GPU, from drivers problems using windows XP, the original O.S. in this system until the problem I'm showing you now.

I tried using CentOS with boing and I was unable to configure the system to work with GPU in a headless system (working like a server, without monitor and accesing over ethernet).

I'm opened to use another O.S. like ubuntu or any where I can use reasonabilly stable this system with its actual resources and chrunching CPU + GPU at the same time. Any suggestions?

Raúl.
