    Hi,
    I have recently installed Kubuntu 16.04 on my amd (Firepro W2100) pc. I used same hardware at Boinc Einstein@home opencl-ati tasks without any problem(Fedora 22). Also I have installed amdgpu-pro drivers to gain opencl support.

    Everything(X apps) works without problem. But I am suffering computation error at opencl-ati(Einstein@Home's Gamma-ray pulsar binary search #1 on GPUs 1.17) tasks. I have also installed amd APP Sdk but nothing changed(I guess It doesn't necessary).

    What should I do to finish opencl-ati tasks without problems.
    Thanks in advance.

      Hi and welcome to the message boards!

      Looking at some of your failed tasks the stderr log shows the following error:

      boinc_get_opencl_ids returned [0x195caa0 , 0x7fedc9183db8]
Using OpenCL platform provided by: Advanced Micro Devices, Inc.
Using OpenCL device "Hainan" by: Advanced Micro Devices, Inc.
Max allocation limit: 985393152
Global mem size: 1476169728
Couldn't create OpenCL command queue (error: -6)!
OpenCL shutdown complete!
initialize_ocl returned error [2013]
OCL context null
OCL queue null
Error generating generic FFT context object [5]
03:44:50 (29131): [CRITICAL]: ERROR: MAIN() returned with error '5'

      Something seems to prevent the app from using OpenCL and so it fails. I would start looking at the graphics drivers and make sure OpenCL support is installed and functioning properly.
      As I'm not a Linux user maybe someone else can use the above info and give better advice.

        https://streamcomputing.eu/blog/2013-04-28/opencl-error-codes/

        shows

         

         -6 CL_OUT_OF_HOST_MEMORY   if there is a failure to allocate resources required by the OpenCL implementation on the host.

         

        what should appear is something like...

        boinc_get_opencl_ids returned [0x22693e0 , 0x7fa9b1397db8]

        Using OpenCL platform provided by: Advanced Micro Devices, Inc.

        Global mem size: 4344250368

        OpenCL device has FP64 support

         so a new version after the holiday period which needs less VRAM should help here.
