Install OpenCL on Ubuntu 17.04, Intel

I'm trying to install OpenCL on ubuntu 17.04 with:

$ lshw :

     *-cpu
          product: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
          vendor: Intel Corp.
          physical id: 1
          bus info: cpu@0
          size: 2899MHz
          capacity: 3100MHz
          width: 64 bits

        *-display
             description: VGA compatible controller
             product: 3rd Gen Core processor Graphics Controller
             vendor: Intel Corporation
             physical id: 2
             bus info: pci@0000:00:02.0
             version: 09
             width: 64 bits
             clock: 33MHz
             capabilities: vga_controller bus_master cap_list rom
             configuration: driver=i915 latency=0
             resources: irq:34 memory:a0000000-a03fffff memory:90000000-9fffffff ioport:2000(size=64) memory:c0000-dffff

So far, haven't been able to find any docs. Intel's "install.sh" reports unsupported OS.

---- As per @Thomas, I've installed: apt-get install beignet clinfo

So far there does not seem to be opencl gpu support

Here is the clinfo output:

You can install beignet package for use with Intel, and clinfo will be helpful to check what is recognized.

apt-get install beignet clinfo

Then run clinfo to check the openCL devices.

clinfo

Depending on your plans, you also might want to have to install development packages or other libraries as well.

apt-get install beignet-dev 

For libraries or programmes you are interested in use the command as follows to find them.

apt-cache search opencl
  • revised question with clinfo output. This doesn't seem to have worked. – iamacomputer Sep 2 '17 at 17:21
  • beignet is only for intel GPUs and doesn't enable OCL for CPU compute. – Andreas Hartmann Jan 10 at 12:09
