    There is capable Intel GPU as part of Ivy Bridge device. It's idle (and log confirms that). But 0 secs of work asked for it it seems. Why so? How to fix ?

    And another attempt:

      I followed your link to the server logs and found this message:

      2013-09-23 21:09:41.4003 [PID=11917] [version] OpenCL device version required min: 102, supplied: 101

      Could a driver update fix this or is it hardware dependent?

            My client asks for intel GPU work, but looks like intel_gup plan class not checked by server at all, only CPU, ati and cuda.
            Why so and how to fix?
            Is it client issue or server setup issue?

              The opencl-intel_gpu apps are thrown in with the CPU apps in the BRP (Arecibo) Search, so probably configured as a CPU app, as opposed to an Intel GPU app.

                  And I had GPU enabled (GPU app) but CPU (CPU app) disabled.
                  Well, Ok if it's known feature but I would say not obvious feature for project newbie. Maybe worth to make it more clear on properties page.

                    It seems really odd to me. Looking at the valid tasks page for Richard's host with Intel graphics on it, the Binary Radio Pulsar Search (Arecibo, GPU) selection has no entries, while the Binary Radio Pulsar Search (Arecibo) selection has lots of returned work. Just to add to the noise, the Application column on that page for these tasks includes the string "opencl-intel_gpu".

                    So in order to get intel GPU work, you must tick the (apparently) non-GPU box if you are not just allowing everything!

                    I'd venture that will mislead plenty of people.

                    I'm contemplating a build soon using an i3-3225 (2-core Ivy Bridge including HD 4000) with GTX650. This preference behavior would have tripped me up for sure.

                      This is what Bernd Machenschalk said almost two months ago:

                      As you can see on the Applications page the only (active) intel_gpu application version is for BRP4 ("Binary Radio Pulsar Search (Arecibo)"). I agree that this is somewhat confusing as BRP4 is a CPU application. It stems from the fact that the Intel GPUs are only available as part of a CPU and are not as powerful (speed & RAM) as what we usually have for GPU applications.

                      Sending (some) poor Intel GPUs WUs that are designed for more powerful GPUs caused more trouble (in terms of reported errors) than we got computing power from these, so we decided to send these small CPU work units.
