    I haven't been getting any work since around the 16th of May. Had some trouble with nvidia driver around then so probably had a bunch of work units return errors in a row, but everything is working now. But can't get any work.

      According to your host's last scheduler contact your host doesn't support openCL. I suspect you have had a Windows update recently that has forced its version of GPU driver on you.

      You need to install or re-install a driver direct form nVidea to get crunching again :-)

        I also just had this issue on

          I also just had this issue on Ubuntu 18.04. Apparently, the Nvidia driver that is available from the "Additional Drivers" section in the "Software and Updates" window only installs CUDA.

           

          To get OpenCL, I had to install the "boinc-client-opencl" package. (Technically this just installs the "ocl-icd-libopencl1" package, but it's a nice shortcut)

            I'm having the same problem.  5 of 6 projects are not downloading new work.  I've reinstalled BOINC and the drivers.  I've removed and re-added the projects.  Nothing is working.

            You can't be having the same

              You can't be having the same problem (graphics driver not having the needed OpenCL compute libraries installed) because neither of the two hosts you have attached to this project have an nVidia or an AMD graphics card.  Only one of those hosts has made a recent contact with the project.

              Perhaps you might like to tell us what particular search or searches you have selected in your project preferences? When was the last time you got work for any search?  Have you made any changes to your project preferences recently?

              You mention you have 6 projects that you support but only one is getting work.  Can you mention all your projects and tell us which is the one that gets work.  Could it be that that particular project is behind in its share of your resources and BOINC is favouring it in order to help it catch up?

              Have you looked at the scheduler logs to see what happened the last time your active host contacted the servers?  In the 'Getting Started' forum there is this pinned thread that explains how to do that.  Here is a snip from the last contact for the active one of your hosts.  I've trimmed time, date, process ID (ie. this bit -> 2018-07-20 02:56:15.5835 [PID=18127]) from the beginning of each line so there's no line wrapping in the middle of messages.  The lines labelled [debug] can be ignored (info for the Devs).

              If you look at the parameter 'work_req_seconds' you can see that your BOINC client wasn't requesting any work.  Either you have preference settings that don't allow work to be requested or perhaps your client thinks that some other project is more worthy at this time.

              I notice that your BOINC client is version 7.12.1 which (I think) is very recently released.  Your problem could always be some sort of new client bug.  Did the problem coincide with the install of 7.12.1?

               

              Cheers,
              Gary.

                i have two pcs at home both running boinc but only one will use the gpu. Ive tried uninstalling and reinstalling boinc, updating gpu drivers, but i have a few projects that could use gpu but on one rig they wont. boinc is detecting my gpu in both rigs but it will not accept work for the gpu in the gaming rig. please help. here is the boinc event log

                  Here is the relevant bit from the above scheduler log excerpt.

                  NVidia device (or driver) doesn't support OpenCL

                  Windows apparently has a habit of updating graphics drivers and leaving out the compute libraries.  Gavin answered this same situation earlier in this thread.  This problem comes up quite regularly.  I don't use Windows at all so I'm just repeating what others have said.  The solution is to go to the nVidia website and download the full package.  You then have to completely remove the Microsoft driver and do a clean install of the full package from nVidia.

                  Gary.

                    I get my drivers from nvidia and have tried this several times and tried again this weekend but still no success. I get the same error NVidia device (or driver) doesn't support OpenCL no matter what i do.

                      Apparently, there is a bit of a knack as to how you install the drivers.  As I said, I don't use Windows so I have no direct experience.  Your problem will most likely be incorrect installation of the OpenCL libraries that are part of the full driver package.  There have been lots of previous examples of this problem over the last couple of years.

                      Have you tried a search here for some of these?  I just did a search for "nvidia AND driver AND clean AND install" so as to only find messages that contain all 4 words.  There were lots of hits.  As I recall, there was quite a lot of emphasis on doing a 'clean install', even to the point of running special apps to clean out any old driver remnants that might be interfering with the new install.  I also recall comments about selecting particular options in the install process itself.  I'm sure you'll find reference to these things if you look through some of the search results.

                       

                      Cheers,
                      Gary.
