app_config.xml settings to use both ATI and Intel GPUs with different number of tasks

Topic 197286
(moderation:
I have just managed to get a test computer http://einsteinathome.org/host/6684790 running with both ATI and Intel gpu's running.
However, my problem is that I want to control the number of tasks running on the different gpu's, but the applications short name is the same for both.
How can I do this?
einsteinbinary_BRP4
8
0.25
0.25
einsteinbinary_BRP4G
8
0.25
0.25
einsteinbinary_BRP5
8
0.25
0.25
I was going to try the below code for the intel_gpu, but I don't know the 'cmdline' parameter?
einsteinbinary_BRP4_1.34_windows_x86_64__opencl-intel_gpu.exe opencl-intel_gpu 0.5 0.5
My goal is to run 4 x tasks on the 7970 and 2 x tasks on the Intel gpu, as test shows that running 4 tasks on the Intel gpu does not perform as well as another computer that only runs 2 task.
Any suggestions?
Many thanks

The short names are not the same!
einsteinbinary_BRP4 = Binary Radio Pulsar Search (Arecibo) and is sent to Intel GPU, Android and ARM devices.
einsteinbinary_BRP4G = Binary Radio Pulsar Search (Arecibo, GPU) and is sent to Nvida and AMD GPUs.
einsteinbinary_BRP5 = Binary Radio Pulsar Search (Perseus Arm Survey) and is sent to Nvidia and AMD GPUs.
Have you tried that app_config? It should work if you change it to this:
[pre]
einsteinbinary_BRP4
0.5
0.5
einsteinbinary_BRP4G
0.25
0.25
einsteinbinary_BRP5
0.25
0.25
[/pre]
The tag is not needed in most cases.

You're running the wrong Boinc version for trying that new development feature, it was introduced into Boinc 7.2.29, and is is 7.2.30 and 7.2.32,
Boinc 7.2.31 is 7.2.28 with Bug fixes, Boinc 7.2.33 is 7.2.31 with further fixes, they don't have the extra development features.
You don't necessarily need to supply cmdline parameters.

Are you sure that the BRP4 app is not also for CPU, as I had an earlier version of this app and I don't think I have ever had the Intel gpu working before.
Here is the older file: einsteinbinary_BRP4_1.33_windows_x86_64__BRP4X64.exe
However, in the interim, I have just done what you suggested and lowered the count for the app.
Thanks

Hi Claggy
I have upgraded to Version 7.2.33, but it has no affect on number of tasks running. Is this replacing the tag?

Yes, see Bernd's post in Technical News
BRP4 for CPU was disabled as we are running out of data to process.

Thank you for that info.
