Hi,
I just got a new laptop, Acer Nitro 5 running an Intel core i5-7300HQ processor and an Nvidia GForce 1050ti (4GB). When we started getting work units again (by the way Thanks Eric and crew, Great Job!! ) I noticed that both the Intel graphics and Nvida are processing work units. I'm assuming that the Intel graphics is embedded in the processor. Specs say it's an Intel HD 630.
I'm running an "ap_config" file,
<app_config>
<app>
<name>astropulse_v7</name>
<max_concurrent>9</max_concurrent>
<gpu_versions>
<gpu_usage>.16</gpu_usage>
<cpu_usage>0.3</cpu_usage>
</gpu_versions>
</app>
<app>
<name>setiathome_v8</name>
<max_concurrent>12</max_concurrent>
<gpu_versions>
<gpu_usage>.16</gpu_usage>
<cpu_usage>.50</cpu_usage>
</gpu_versions>
</app>
</app_config>

This gives me 3 cores and 3 graphics, however with both graphics cards running I'm getting 6 WU for the graphics cards (3 each)
This is probably way too much work for the laptop, so how do I either stop the Intel graphics card from doing work or adjust the ap_config file to limit the work?

Just got the laptop, don't want to burn it out in a week :-)

Go to your Seti account, Seti@home preferences, deselect "Use Intel GPU". Save changes. Next time the client on the computer contacts the Scheduler it'll get the changed settings (or you can manually click on Update). That should allow the laptop to finish the iGPU work it has, and not get any more.
Generally the use of an integrated GPU actually results in less work being done than just using the CPU alone.
With the iGPU disabled the CPU and Nvidia GPU will be able to pump out plenty of work.

Thanks Grant, I unchecked the box, Like you said I guess it will process all the intel gpu's and then stop. I got a bunch of them :-)

Grant, I don't know if its just a SETI issue but when I was testing a new app over at folding@home the iGPU actually improved CPU output by 50%

You can't compare credit or run times between projects as the tasks and applications are so different.

However a lot of folks have found that the Intel GPU is a considerable drain on the CPU, to such an extent that they don't use the Intel GPU for processing on SETI at all.
