I have heard, it is possible to run multiple task on one GPU. This has benefits, because the GPU will stay at 100% and will complete morse tasks in the same time.
You have to edit a config file as far as i know. This is about the OPNG Covid GPU workload. |

Add an app_config.xml file to the WCG projects directory, example contents at link below, other examples in that thread and others.

Thanks, that helped me on my Windows computers, too! Is it also possible to run multiple GPU WU's under Linux (Ubuntu 20.04)? I am guessing the approach would be somewhat different as the folder structure is completly different compared to Windows. A Boinc directory I couldn't find let alone set up an app_config file.

Same for all, Linux, Windows or Mac.
----------------------------------------File app_config.xml in the project folder. On my Ubuntu 20.04 it is under /var/lib/boinc-client/projects. Many examples in GPU threads here and elsewhere. Adjust numbers to suit, e.g. .25 for 4 at once. Paul.
