I suggest to add a Boinc feature to run multiple project tasks on a single GPU for stock project executables without the use of app_info.xml (<count>.33</count>).

On average, I went from 1 SETI task per GPU at 210s/cuda task to average 170s per cuda task while running 3 at same time.
GPU-Z stated from 75% GPU load to 98%.
All other variables were the same.

They beat you to it - already implemented!

You need one (or more) app_config.xml file(s) - details are in the final section of application configuration. You can even load the app_config files and change the GPU loadings on-the-fly without exiting BOINC - though you are recommended to upgrade to BOINC v7.0.64 first - the recommended version since yesterday.

Cool!!!

But I can't make it work for SETI. :(

I tried with Boinc 7.0.64, 64bits
app_config.xml in Project directory and Boinc reloaded:

<app_config>
<app>
<name>setiathome_enhanced</name>
<max_concurrent>4</max_concurrent>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
</gpu_versions>
</app>
</app_config>

And could not find a working example for seti.

OK, I made it work!

I went from 73% GPU load to 92% with:

<app_config>

<app>
<name>setiathome_enhanced</name>
<max_concurrent>5</max_concurrent>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>0.2</cpu_usage>
</gpu_versions>
</app>

<app>
<name>astropulse_v6</name>
<max_concurrent>1</max_concurrent>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>0.2</cpu_usage>
</gpu_versions>
</app>

</app_config>
