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.

good question -
my impression within the last weeks has been the GPUGRID staff is now a lot more concentrating on the CPU tasks (Quantum Chemistry), resulting in more frequent periods of time where GPU tasks are NOT available.
Although QC is a minority program only, not being available for Windows users.

In a way this is really too bad for all the crunchers who for one reason or the other want to stick with Windows: CPU jobs cannot be processed, and GPU jobs are not available :-(

Of course, everyone who wants go keep his/her GPU busy can choose from a variety of backup projects;
however, it should be clear to GPUGRID that there may be cases where crunchers do not return to GPUGRID once they satisfactorily participate in another project - particularly if there is a much better and more reliable availability of work.

somehow I would have expected some kind of statement from the GPUGRID people in reply to my posting above. Well, nothing so far :-(

A look at the current Server Status page shows interesting figures:

GPU tasks - unsent: 0; in progress: 1.761; users in last 24hrs: 924

CPU tasks - unsent: 44.723; in progress: 848; users in last 24hrs: 76

this alone shows the huge imbalance. 924 GPU users have no news tasks available, and 76 CPU users have 44.723 available.
What sense does this make?

There are about 12x more GPU users, not getting new taks. Whereas only 76 users are swamped with 44.723 tasks.

Where is the logic behind this?

I hope all this work on cpu helps the advancement of science on gpugrid. :-)
It's not so clear what we are crunching on our cpu....

What is not clear about what we are crunching on CPU? If you have any doubts or questions I'll be glad to answer them.

After reading what is printed in the output directory of stderr.txt I would welcome a short explanation of what the program is doing. I have taken a structural chemistry course in my university years, talked with Enrico Clementi while working at Mondadori Scientific Publishing and followed some lectures on Density Functional Theory while at Trieste Area Research Park.

The overview that Stefan gave is good enough for me. I expect we will have to await the details until the publication(s). There should be a series of them.

too bad that there still is no reaction or reply from GPUGRID side to my above posting.

It can be reduced to the main question: is there a continuing, long-term tendency towards CPU tasks, with a decreasing focus on GPU tasks?
(I do not remember any siginificant period of time within the past 2 1/2 years where no new GPU tasks were available as it was the case within the past weeks).

I guess I am not the only one who would be interested in getting some kind of information.

This is my doubt. I had already read the Stefan post and i understood the "tecnical part" (and it's very interesting), but i don't know what we are crunching for: Hiv? Cancer??? Just a curiosity
I'll wait publications :-)
And i'll wait for windows client :-))
