Hi All,

In one of my systems I am trying to run a 3090 RTX card (This works) along with a Quadro M4000 (8GB version). I can only get tasks to run on the 3090. I am trying to get both of them going at once. What am I doing wrong?

Also is there any way to run more than one work unit per GPU? This project hardly uses my 3090.

Other info.....

CPU: Ryzen 5900x
RAM: 64 GB DDR4
OS: Win 10.

Boinc by default will only use the most capable card based on certain criteria. You can make Boinc use all your cards if you add

<use_all_gpus>1</use_all_gpus>

in the <Options> section of your cc_config.xml file.

If you want to run multiple concurrent tasks on a gpu you need to create a app_config.xml file and put it in the project directory. Its contents will look like this for running 2X per card:

<app_config>
<app>
<name>period_search</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.1</cpu_usage>
</gpu_versions>
</app>
</app_config>

Thanks Keith. That worked; however the 3090 is taking 20+ days now estimated to complete a work unit? I think something is off.

Until Boinc sees 11 validated tasks, for both gpu tasks and cpu tasks, it can't develop a proper APR rate for the host which is necessary to project CORRECT estimated finish times.
