Things that worked for me in Ubuntu 16.04

I have installed openCL on:

SandyBridge CPU: cpu only

IvyBridge GPU

Nvidia GTX 950

install packets

Generic ubuntu packages for OpenCL

Basic installation sudo apt install ocl-icd-libopencl1 sudo apt install opencl-headers sudo apt install clinfo

Package that allows to compile OpenCL code (1.2 I think)

Needed to link and compile sudo apt install ocl-icd-opencl-dev

For Intel GT core

Package that enables runnig openCL on Intel GT, IvyBridge and up

sudo apt install beignet

For SandyBridge Intel CPU and possible others

Download this file OpenCL™ Runtime 16.1.1 for Intel® Core™ and Intel® Xeon® Processors for Ubuntu* (64-bit) On https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_SDK_release

Install packages for turning rpm to deb sudo apt-get install -y rpm alien libnuma1

Untar downloaded file tar -xvf opencl_runtime_16.1.1_x64_ubuntu_6.4.0.25.tgz cd opencl_runtime_16.1.1_x64_ubuntu_6.4.0.25/rpm/ Turn rpm files to deb fakeroot alien --to-deb opencl-1.2-base-6.4.0.25-1.x86_64.rpm fakeroot alien --to-deb opencl-1.2-intel-cpu-6.4.0.25-1.x86_64.rpm Install .deb packages sudo dpkg -i opencl-1.2-base_6.4.0.25-2_amd64.deb sudo dpkg -i opencl-1.2-intel-cpu_6.4.0.25-2_amd64.deb Touch local config file sudo touch /etc/ld.so.conf.d/intelOpenCL.conf Open the file sudo vim /etc/ld.so.conf.d/intelOpenCL.conf and add the line

/opt/intel/opencl-1.2-6.4.0.25/lib64/clinfo

Create a vendors dir and add intel.icd sudo mkdir -p /etc/OpenCL/vendors sudo ln /opt/intel/opencl-1.2-6.4.0.25/etc/intel64.icd /etc/OpenCL/vendors/intel64.icd sudo ldconfig

test if this worked

clinfo should list your devices Dowload this file

https://codeload.github.com/hpc12/tools/tar.gz/master

Run this code to make sure everything works tar xzvf tools-master.tar.gz cd tools-master make ./print-devices ./cl-demo 1000 10 This should print out GOOD in the end

For Nvidia

install nvidia drivers (I used 370), this should include all the runtime dirvers
