Message 1698848 - Posted: 6 Jul 2015, 1:00:09 UTC - in response to Message 1698667.

I have tracked down the settings in my Surface 3 tablet. I'll know in an hour or so if I have changed the correct parameters. I obviously haven't done any damage. It took a little investigation and reading between the lines to discover the particular files for my GPU. If it works here, Ill change the parameters in my PC when I get to it this evening. Otherwise, Ill keep reading and learning until I get it right.

Example: <app_info>
<coproc>
<type>intel_gpu</type>
<count>.5</count>
[/color] </coproc>
<file_ref>
</app_info>

That [/color] shouldn't be there. The rest of it looks OK.

There are newer apps you could be using. I'd switch to those before you started any other changes.
The ATI HD5 App looks to be the slightly older version than what's currently on the server, but it's better than what you are using. You can find them here, http://mikesworldnet.de/download.html

Just make sure you keep the same Version number and Plan_class that's in your current app_info or the server will trash all your current tasks;
<version_num>703</version_num>
<plan_class>opencl_intel_gpu_sah</plan_class>
BTW, it appears both your <app_version> sections use the same plan_class;
<plan_class>opencl_intel_gpu_sah</plan_class>
<plan_class>opencl_intel_gpu_sah</plan_class>
You only need 1 <app_version> per plan_class, the idea behind different <app_version> sections is to cover different plan_classes. But, yours appears the same.

I'm still trying to decipher your Tahiti times. The only thing that makes sense is if you are running 4 tasks at once, but, it doesn't appear you are. Strange.
You do have a free CPU core to feed the Tahiti, right?
Also, when you make changes to your app_info.xml you have to restart BOINC for the changes to take effect.

[/color] was accidently inserted when I tried to highlight the <count>.5</count> in my post. The change I made was from 1 to .5. The change wasn't made in my config file. It doesn't seem to have changed anything. My GPU is PowerColor Radeon R9 280X (AXR9 280X 3GBD5-DHE) 3 GB GDDR5. I really don't wish to be a bother. I really am just experimenting with the possibility of multiple WUs running on my GPU, out of simple curiosity. Thank you for your time.

<count>.5</count> was <count>1</count> in all instances I could find. I doesn't seem to have changed anything. Any suggestions are appreciated.

Well first I would start by saying that running more than one instance on your iGPU isn't going do you anything for you, but it may prove an interesting exercise.

Secondly there is a newer more user friendly way to change the number of instances per device that doesn't rely on an app_info.xml.
You can create an app_config.xml. Then your settings are in place when you change the the latest lunatics version & you don't have to hunt through your app_info.xml looking for each instance of <count> to change.

AAHHHhh... I was under the impression I could run multiple WUs on a single GPU, usefully of course. I appreciate the insight. I have just ordered a matching GPU, the very same model (hard to find). I have read that Crossfire may cause problems, however, I don't need crossfire for Seti and I don't need it for the single video game I play occasionally, Hawken. It already plays at ultra settings. I'll check back when I have the new GPU. Peace!

I think you misunderstood Hal, You do want to run more than 1 instance on your R9. I run 2 but have been told 3 should be no problem. Hal mentioned that you can configure lunatics to do this for you. I don't use Lunatics so I have no idea of how it is done but lots of crunchers use it and love it.

2 of those R9's should burn through WU's like mad. Just make sure you have some CPU cores left open to feed the CPU.

I'll check back when I have the new GPU. Peace!

The reason to run more than 1 task at a time on a GPU is because on mid to high end GPUs a single application instance does not make full use of it. Sometimes only 30 to 40%. Then running 2-3 instances will make full use of of the GPU. If you use an application like GPUz then you can see how much use of your GPU a single instance is using.

This is an example of one of my HD 6870s running 1 AP task. The GPU load runs 95-99% so that GPU does not have any overhead to run a 2nd task. Some say if the GPU is already over 80% then 1 task.


Given that your R9 280X is at least twice at powerful as an older HD 6870 I would hazard a guess that 2 at time would be no sweat for it.

What I was mentioning is that the iGPU(Intel GPU) you were showing the configuration for is not that powerful. It will already be working at full tilt with just 1 task.

Also. When adding or changing config settings in the .xml files for BOINC you will either need to use the "read config file" menu option or restart BOINC for the new settings to take effect.

Joe Segur created this app_config.xml for me about a year ago. It has been working fine; and all my MBs validate; both on Exeter, (GTX-760), and Prometheus, (GTX-750 TI), so it should be fine.

WOW! That was instantaneous! Thank you! I'll keep an eye on things to make sure it is stable. Otherwise, indications are that it is crunching 3 WUs at a time, estimated completion 30mins each. Too cool....

Yes. you use Nvidia GPUs. Which run CUDA for setiathome_v7. Louis is using ATI GPUs which uses OpenCL to run setathome_7. Comparing apples to potatoes there.

Apples to potatoes in that CUDA doesn't use much CPU overhead like OpenCL seems to. The use of -cpu_lock can sometimes be used in place of reserving a CPU core/thread. Depending on the system. For AP tasks on my ATI GPUs I don't have to reserve a CPU core/thread when using -cpu_lock, but for MB I do need to reserve a core/thread.

It makes a Big difference when you have a Free CPU Core or 2, 3... feeding your GPU doesn't it? Your times are about normal now. Just change the <max_concurrent> line to reflect how many tasks you want to run, including the GPU tasks. So, if you are running 2 GPU tasks and want to run 6 CPU tasks change it to 8, as so,
<app_config>
<app>
<name>astropulse_v7</name>
<max_concurrent>8</max_concurrent>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.33</cpu_usage>
</gpu_versions>
</app>
<app>
<name>setiathome_v7</name>
<max_concurrent>8</max_concurrent>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.33</cpu_usage>
</gpu_versions>
</app>
</app_config>

Then Go to the Advanced Menu and select 'Read config files'. If you haven't changed anything else that should do it.
If you notice the GPU times slowing down, change the <max_concurrent> to 7, etc.

You are the best. Really. I always look forward to learning something new every day. Running two GPU and six CPU WUs. The two free CPUs should remove any lag I may have had in regular operations(none that I realized).That should really kick up my RAC. I'll keep you guys up to date. Peace!

Louis Loria II .I haven't got the Intel Quad 8450 running Seti at the moment .

Sounds like your doing MB's try AP's

My current RAC ,1 machine the AMD with 2 GTX 650's 22,700

the Intel does AP's faster 8 hours 20 min , currently 11 hours.12 min per unit on CPU witch is AMD FX 4350 8 core
