Any comments please?

Hello jleitch2013,

I will have someone from the IGC team look into this shortly. In the meantime can you please include some additional details regarding the steps up to this point? Did you see any errors during the build or the install process?

Thanks,
Alex

Hello Alex, Good morning, and  thanks for your reply. Here is some background to my question: I am using Python 2.7 and starting to use the Quantum processing features in this language, with the Intel i3 i8300 CGU on my linux system , 64-bit ,( kernel 4.19.8-1-default #1 SMP PREEMPT) I load the pyopencl library (>>> import pyopencl as  cl,  numpy) try and select a context with >>>ctx  = cl.create_some_context() and I am offered the platform:Choose platform: [1] <pyopencl.Platform 'Intel Gen OCL Driver' at 0x7f7020ea6c60> The response is: cl_get_gt_device(): error, unknown device: 3e91 Running oscli on the command line confirms this, gives me the response sent previously. The Intel graphics compiler was downloaded from github, the dependencies also downloaded following the instructions given, and the compilation completed with only a few minor warnings. The installtion was completed without any errors. However Python apparently does not seem to recognise the hardware! I was surprised there was not any installation script (python.setup) to be run to tell Python about the CGU, however this may just  be my understanding, and not necessary. Thanks for your assistance.

Hello James,

After evaluating your issue further it appears that you need to install the new Intel Graphics Compute Runtime for OpenCL located here (https://github.com/intel/compute-runtime). The legacy runtime that you have installed currently (Beignet) is not supported for your machine with the latest igc driver. Please follow the installation steps located on the the compute-runtime ReadMe and let me know if you have any additional question or problems during setup.

Thanks,
Alex

Hi Alex,Thanks for the suggestion. I downloaded and recompiled, and I'm still getting the error message. The new  Intel context is selected by default. Here is my Python code: jleitch@BOSTON:/usr/usr1/QUANTUM/SAMPLES/MonteCarlo> python Python 2.7.15 |Anaconda, Inc.| (default, Dec 14 2018, 19:04:19)   [GCC 7.3.0] on linux2 Type "help", "copyright", "credits" or "license" for more information.

cl_get_gt_device(): error, unknown device: 3e91 cl_get_gt_device(): error, unknown device: 3e91

Hi James,

it looks like you python still trying to use Beignet driver. Error message:

cl_get_gt_device(): error, unknown device: 3e91

comes from Beignet.

can you share output from command: ls -l /etc/OpenCL/vendors/?
could you install clinfo in your system and check whether it reports

Device Name                                     Intel(R) Gen9 HD Graphics NEO

I tried your python code, here is my output:

# python

[2] <pyopencl.Platform 'Portable Computing Language' at 0x7f92d3730020>
Choice [0]:1
Set the environment variable PYOPENCL_CTX='1' to avoid being asked again.
>>>

As you can see I have more than one platform installed and it works. but this may be hint: PYOPENCL_CTX='1'. do you have this environment variable set?

regards,
Artur
