Message 1641410 - Posted: 13 Feb 2015, 20:18:26 UTC

One of my hosts has two GTX 970's and also an integrated GPU (intel HD4600). I run multiple WU's concurrently on the 970's but would like to limit the 4600 to one at a time. Is there a way to do that?

Also, are there any recommended settings for mb_cmdline_win_x86_SSE_OpenCL_Intel.txt?

Have you tried an app_config.xml with the <app_version> settings?

<app_config>
[<app>
<name>uppercase</name>
<max_concurrent>1</max_concurrent>
[<fraction_done_exact/>]
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.4</cpu_usage>
</gpu_versions>
</app>]
...
[<app_version>
<app_name>uppercase</app_name>
[<plan_class>mt</plan_class>]
[<avg_ncpus>x</avg_ncpus>]
[<ngpus>x</ngpus>]
[<cmdline>--nthreads 7</cmdline>]
</app_version>]

...
[<project_max_concurrent>N</project_max_concurrent>]
</app_config>

This is my current app_config

<app_config>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>0.1</cpu_usage>
</gpu_versions>
</app>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>0.2</cpu_usage>
</gpu_versions>
</app>
</app_config>

I'm sorry, I don't understand the syntax of your example.

This is my current app_config

<app_config>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>0.1</cpu_usage>
</gpu_versions>
</app>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>0.2</cpu_usage>
</gpu_versions>
</app>
</app_config>

I'm sorry, I don't understand the syntax of your example.

Something along the lines of this
<app_config>
	<app_version>
		<app_name>setiathome_v7</app_name>
		<plan_class>CUDA50</plan_class>
			<ngpus>0.33</ngpus>
			<avg_ncpus>0.1</avg_ncpus>
	</app_version>
	<app_version>
		<app_name>setiathome_v7</app_name>
		<plan_class>opencl_intel_gpu_sah</plan_class>
			<ngpus>1.0</ngpus>
			<avg_ncpus>0.1</avg_ncpus>
	</app_version>
	<app_version>
		<app_name>astropulse_v7</app_name>
		<plan_class>opencl_nvidia_100</plan_class>
			<ngpus>0.33</ngpus>
			<avg_ncpus>0.2</avg_ncpus>
	</app_version>
	<app_version>
		<app_name>astropulse_v7</app_name>
		<plan_class>opencl_intel_gpu_102</plan_class>
			<ngpus>1.0</ngpus>
			<avg_ncpus>0.2</avg_ncpus>
	</app_version>
</app_config>

You would need to match the values in <plan_class></plan_class> with the ones you are using in your app_info.xml

Thank you so much! I'll give it a try. :-)

UPDATE: Worked perfectly. Thank you again!
