The server status page shows that there are tasks for "Short runs" and "Long runs", but I am not getting either of these tasks on my PC. The event log entries are:

GPUGRID | Sending scheduler request: To fetch work.
GPUGRID | Requesting new tasks for NVIDIA GPU
GPUGRID | Scheduler request completed: got 0 new tasks
GPUGRID | No tasks sent
GPUGRID | Tasks for CPU are available, but your preferences are set to not accept them

I did see another topic stating that CUDA 8.0 is required, but the BOINC logs suggest that I am running 9.1:

CUDA: NVIDIA GPU 0: GeForce GTX 760 (driver version 390.48, CUDA version 9.1, compute capability 3.0, 1992MB, 1545MB available, 2620 GFLOPS peak)

My account preferences are set to accept all applications, with "Use CPU" set to "no".

I am running on Ubuntu 18.04 LTS with Nvidia driver 390.48. Do I need to install a separate CUDA package to get GPU tasks?

I have not found it necessary to install a separate CUDA package on Ubuntu 18.04.

EDIT: Let me clarify that. I had to install the "Nvidia driver metapackage from nvidia-driver-390 (proprietary, tested)" from Ubuntu Software & Updates in order to get the OpenCl drivers. It did not used to be the case for Ubuntu 16.04, but that seems to have changed somewhat, and may be necessary for CUDA too.

These preferences work for me:

Resource share 100
Use CPU no
Use ATI GPU no
Use NVIDIA GPU yes
Run test applications? no
Maximum CPU % for graphics 20

Run only the selected applications
ACEMD short runs (2-3 hours on fastest card): no
ACEMD long runs (8-12 hours on fastest GPU): yes
ACEMD Beta: no
Quantum Chemistry (CPU): no
Quantum Chemistry (CPU, beta): no
Python Runtime : no
If no work for selected applications is available, accept work from other applications? yes
Use Graphics Processing Unit (GPU) if available yes
Use Central Processing Unit (CPU) yes


Also, in BOINC Preferences, do you have "Use GPU while computer is in use" enabled?

According to this post, the present Linux app (v9.18) does not support cc3.0 cards (so called shader model 3.0, sm3.0). The older v8.49 app (CUDA6.5) supports cc3.0 cards, but there's only Windows version of this app. So you have to use Windows to make your cc3.0 card work with GPUGrid.

I had to add the nvidia PPA to get drivers to work with BOINC in 18.04. I don't recall if that was for OpenCL or CUDA. One was missing.

In that case, I will unfortunately be unable to contribute to this project (at least for GPU tasks). I do not have a Windows PC, and I do not plan to use Windows in the forseeable future.

I have a like problem: I'm getting CPU tasks but no GPU.

Fedora-25, 7.8.4 x86_64-pc-linux-gnu, GeForce GTX 770

Do I have a configuration problem or as above there is nothing I can do to use my GPU?

Thanks

Currently there are no more "unsent" GPU work units.

Looks like the GPU well has run dry...

Some new GPU WU's will be generated from returned results...keep trying.

I am still getting both CPU and GPU tasks on my main Linux box. A Linux laptop, with no GPU board, is getting CPU tasks.

They were going to update the name but couldn't because the recaptcha is still out of date. /snark
