Right, you seem to have internal Intel GPU as well and Dnet OpenCL app detects that and tries to use but fails to. There's two problems here, first that the Intel GPU fails to run the app and second that it gets detected by the Dnet app so the GPU numbering is out of sync with BOINC Client.

BOINC Schduler should have given up after 10 failures on the OpenCL app but doesn't seem to be doing that. I'll try to figure out if this can be fixed (you should only be getting the cuda31 app until problems with Intel GPUs can be fixed).

I've never used the Intel GPU for crunching so it's probably got none of the correct drivers.

The task does indeed give up after ten goes of trying to use the Intel GPU ... and then moves onto the next task and repeats.

I tried to download work again last night and got "191 Distributed.net Client v1.04 (opencl_nvidia_101)
windows_intelx86" tasks.

Some Cuda ones would be nice as the external GPU has no issues with them.

It's happened before but it's not my issue, I don't run any anti virus on my crunching machines.

I have several hosts running Moo and the only ones having problems are the ones with GTX 1080 GPUs in and only with Opencl tasks, everything else runs without problems.

Probably a driver problem but I'm not going to mess around with things at the moment. No matter, I'll move them to a different project.

I've let it run again and tasks now state:
17:45:15 (7524): wrapper v1.4 build 18 for nVidia OpenCL starting (BOINC Wrapper v7.5.26011)
17:45:15 (7524): device: OpenCL: NVIDIA GPU 0 (not used): GeForce GTX 1080 (driver version 378.49, device version OpenCL 1.2 CUDA, 8192MB, 3042MB available, 9395 GFLOPS peak)

So apparently these "Distributed.net Client v1.04 (opencl_nvidia_101) windows_intelx86" tasks are running on the CPU?!

I have a host with two GTX1080s in http://moowrap.net/show_host_detail.php?hostid=798990 and up until a few hours ago they were both crunching the same "Distributed.net Client v1.03 (cuda31) windows_intelx86" tasks quite happily.

Now I'm only getting "Distributed.net Client v1.04 (opencl_nvidia_101) windows_intelx86" tasks which all fail after about 20 seconds with "computation error"

The project attempts to run one task per GPU but GPU-Z shows no load and no power used.

It may have something to do with the message "[May 02 03:32:57 UTC] Automatic processor type detection did not recognize the processor (tag: "Intel(R) HD Graphics 530 ")" in the stderr file.

No changes at my end, another hosts with the same GPUs is also getting the opencl tasks and running them although they are claiming to need over six hours (and increasing) to finish!

I don't use an app_config.
