<p>I have a Linux server with 3 OpenCL drivers, running Ubuntu 18.04 x64:</p>
<h1><a name="clinfo" class="anchor" href="#clinfo"></a>clinfo</h1>
<p>Platform Name Portable Computing Language Platform Vendor The pocl project Platform Version OpenCL 1.2 pocl 1.1 None+Asserts, LLVM 6.0.0, SPIR, SLEEF, DISTRO, POCL_DEBUG Platform Profile FULL_PROFILE ... Platform Name Intel(R) CPU Runtime for OpenCL(TM) Applications Platform Vendor Intel(R) Corporation Platform Version OpenCL 2.1 LINUX Platform Profile FULL_PROFILE ... Platform Name NVIDIA CUDA Platform Vendor NVIDIA Corporation Platform Version OpenCL 1.2 CUDA 10.0.141 Platform Profile FULL_PROFILE ... but for some strange reason, GB4 can see ONLY NVIDIA....</p>
<p>root@gpu-01 ~ # Geekbench-4.3.2-Linux/geekbench4 --compute-list<br>
Geekbench 4.3.2 Pro : <a href="http://www.geekbench.com/">http://www.geekbench.com/</a></p>
<p>CUDA<br>
0 0 GeForce GTX 1080<br>
OpenCL<br>
2 0 GeForce GTX 1080</p>
<p>What is going on ?<br>
(+I have attached 'clinfo' output from Linux)</p>
<hr>
<p>Intel OpenCL driver + Linux OpenCL driver (POCL) install commands on Ubuntu 18.04:<br>
apt-get install ocl-icd-dev ocl-icd-libopencl1 libpocl2 clinfo lsb-core</p>

<p>This configuration is intended for testing and benchmarking, and if it works well, maybe playing some Leela Chess :)</p></div>al4321tag:support.primatelabs.com,2011-01-31:Comment/467627042019-01-08T15:06:54Z2019-01-08T15:06:54ZUnable to detect OpenCL devices<div><p>Geekbench 4 OpenCL Compute Benchmarks only support GPU devices, and the NVIDIA device is the only GPU device in your system (the POCL and Intel devices are CPU devices).</p></div>John
