My goal is to enable OpenCL2.0 features on my Intel graphics (Intel® HD Graphics 510).
After a fresh installation of intel-opencl-2.0-2.0-54425.tar.gz on my Ubuntu 14.04,
finally the sample code CapsBasic can list all my available platforms and devices.
The version of OpenCL driver detected for CPU (Intel(R) Pentium(R) CPU G4400 @ 3.30GHz) is 2.0 as I expect, but is 1.2 for GPU.
I have also tried intel_sdk_for_opencl_2016_ubuntu_220.127.116.110_x64.tgz, which is referred to as Intel® SDK for OpenCL™ Applications 2016 R2 for Linux* (64 bit), either based on previous setup or on a fresh Ubuntu;
after I modify the /etc/ld.so.conf.d/ rules and do sudo ldconfig, there is even no platform can be detected, along with clinfo reporting:
I: ICD loader reports no usable platforms
We just posted a new intel-ocl-r3 driver update on the drivers and runtimes page. If fully installed you should get OpenCL 2.0 features for GPU as well.
From the release notes: This release provides OpenCL 2.0 support for 5th, 6th and 7th generations of Intel® Core™ and Xeon™ processors with Intel® Processor Graphics Technology not previously disabled by the BIOS or motherboard settings.
You will need to install a driver package in addition to the SDK. Installation instructions.
It seems that Intel intel-opencl-r3.0 (SRB3) Linux driver package along with Intel® SDK for OpenCL™ Applications 2016 R2 for Linux* (64 bit) can't work as expected on my Ubuntu configuration after following the installation guide.
The sample code CapsBasic displays:
CL_DEVICE_OPENCL_C_VERSION: OpenCL C 1.2
and clinfo reports:
terminate called after throwing an instance of 'unsigned long'
Aborted (core dumped)
Is there anything else I can do to identify the reason?
