Took me ages to get my NVIDIA GTX 760 card working under linux. Now Boinc Recognizes the card but I don't get any work units for it. Anybody got a clue why I dont get work units ?

---

Any chance we can get a little bit more info than just "I'm not getting work?" Like maybe something from the logs indicating if it is asking for work or if it doesn't need any because you have enough on-hand from other projects?

Place this line in your cc_config.xml file in between the log_flags;
<sched_op_debug>1</sched_op_debug>

That will give you juicy details such as;

I'm getting work for my I7 but no work for the NVIDIA GPU. Seti@home is the only project running at the moment.


Ill try the <sched_op_debug>1</sched_op_debug>

but neither running windows or OSX but Fedora 21 Linux

---

The only GPU app currently for Linux is Astropulse, and with the problems the database has had recently that would account for not getting any work for the GPU.

Also make certain that you are allowing AP work in your preferences.

---

That explains alot :)

---

I'm getting AP units on my other machines.

Just wondering if it has something to do with the driver version

this is what i get from log file

---

It appears you are still receiving all MB CPU tasks. You would think if you have selected AP you might at least get a couple CPU APs. It would be helpful if you posted the Scheduler Request, as I did in my last post, so we could see just what is being requested by your system.

Yes, it appears your driver is the problem. You are missing the OpenCL entry, all it is showing is CUDA. You need OpenCL for AstroPulse. You are going to need the GPU Driver from nVidia and reinstall the driver. I'm familiar with Ubuntu and that's about it as far as Linux versions go. Maybe someone else can help you with your version of Linux...if you need it ;-)

BTW, you can check for OpenCL by opening a Terminal window and typing clinfo. If you have OpenCL it will run clinfo and display results for all your devices that have an OpenCL driver.

Thanks for this thread. I failed to realize I needed opencl for AP!
Now installed opencl and boinc sees CUDA and opencl.

Is there a technical reason that prevents the development or porting of a GPU app for MB WUs under Linux, or is it a case of no one taking or having the time to do it?

Mostly it is nobody really has the experience to port it to Linux and Mac. Jason plans on working on it eventually, but is busy dealing with other stuff currently.

Various of us have our own ports, but it's hard to make a "standard" version due to the large variability between different versions, distributions and libraries. Also, you really need to have a compatible version of BOINC and even that is hard to compile, especially if you want the graphical boincmgr (the standard distribution doesn't work on most of my Linux systems, due to its requiring specific libraries).

---

First, thanks to both of you for taking the time to reply. I run SETI on a server with no GUI so perhaps we might eliminate that part of the problem. Is the source code readily available for download somewhere so that others can play with it? To say I am not the best at working through problems of compiling source code is undoubtedly an understatement, but I learned a long time ago that you do not always have to be good if you are willing to be persistent.
