Hi Nishma,
One thing I am curious about: if you reinstall the AMD SDK, does that fix the problem and do you see the GPU device as well?

Hi Robert,
I tried running GEMM and bitonic sort and it doesn't give error now. They use CPU. Does this means I have install OpenCL correctly? Could you please tell me how to run samples using GPU?
Best Regards,
Nishma Laitonjam

Hi Nishma,
Yes, you installed the CPU OpenCL runtime correctly. You could try to reinstall AMD SDK and see if you could get your GPU OpenCL device back. Your integrated GPU is much too old, so we don't have an OpenCL runtime that supports it.

Hi Tata,
We don't support a GPU driver for Sandy Bridge. Sorry!

Hi Robert,
My environment is ubuntu14.04 64-bit and Intel® Core™ i7-4770 CPU @ 3.40GHz × 8.
I've download and installed the Intel opencl backend from https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_driver.
Also I installed the clinfo: $ sudo apt-get install clinfo
And then I ran clinfo: $ sudo clinfo
But it crashed:
terminate called after throwing an instance of 'unsigned long'
Could you help on it?
Best Regards,
Kris

Hello,
I have the same environment and did exactly what is recommended in https://software.intel.com/en-us/node/671831 after installation of Intel OpenCL from https://software.intel.com/en-us/intel-opencl/download. But, when invoking Eclipse Mars.2 I have messages kind of "Cannot get machine/platform/device list. Failed to initialize code builder API." What may be the problem?
Thanks

Hi Robert,
I have a similar problem to Vitali K. I am using Eclipse Neon and I also get messages of the type "Cannot get machine/platform/device list. Failed to initialize code builder API." The command line version of ioc64 seems to work.
Thanks,
Nik

Hi,
I am trying to install intel SDK for openCL on a virtual machine. when I am trying to install opencl runtime env then it is giving output as "CPU is not supported". I complied the matrix multiplication program. It is compiling with some warning and creating the executable file. But when I am running the executable then it is giving error as follows:
./GEMM: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory
UPDATE:
now I fixed the path problem I think. A new error is coming.
root@VM1:/home/sudiptavm/workvm/codeSamples/withOpenCL/matrix_mult/GEMM# ./GEMM
Platforms (1):
[0] Intel(R) OpenCL [Selected]
Devices (1):
[0] QEMU Virtual CPU version 2.2.0 [Selected]
[ ERROR ] Sample application specific error: OpenCL error CL_DEVICE_NOT_AVAILABLE happened in file ../common/oclobject.cpp at line 447.
How can I solve it?
note: I installed OpenCL in the host machine which has Intel(R) Xeon(R) CPU E31280 @ 3.50GHz
With regards,
Sudipta

What do you see with the system analyzer? https://software.intel.com/en-us/articles/mss-sys-analyzer-linux
You can also see more about how OpenCL initialization is handling this environment with the Platform/Device Capabilities Viewer Sample.

Hi TimurS,
Can you share what CPU SKU the system is on? What kernel the system is on?
For linux setup... please see these two pages:
https://software.intel.com/en-us/articles/sdk-for-opencl-gsg

Hi, I am a new OCL dev trying to get everything off the ground so I can start playing with it.
I am running on an Inspiron prebuilt laptop running window 10 home, and operate in an Ubuntu 16.04.4 terminal.
When compiling through the C++ wrapper I get a large error string as follows:
/tmp/ccTKf6fE.o: In function `cl::detail::ReferenceHandler<_cl_device_id*>::release(_cl_device_id*)': oCLtest.cpp:(.text._ZN2cl6detail16ReferenceHandlerIP13_cl_device_idE7releaseES3_[_ZN2cl6detail16ReferenceHandlerIP13_cl_device_idE7releaseES3_]+0x14): undefined reference to `clReleaseDevice' /tmp/ccTKf6fE.o: In function `cl::detail::ReferenceHandler<_cl_context*>::release(_cl_context*)': oCLtest.cpp:(.text._ZN2cl6detail16ReferenceHandlerIP11_cl_contextE7releaseES3_[_ZN2cl6detail16ReferenceHandlerIP11_cl_contextE7releaseES3_]+0x14): undefined reference to `clReleaseContext' /tmp/ccTKf6fE.o: In function `cl::detail::ReferenceHandler<_cl_command_queue*>::release(_cl_command_queue*)': oCLtest.cpp:(.text._ZN2cl6detail16ReferenceHandlerIP17_cl_command_queueE7releaseES3_[_ZN2cl6detail16ReferenceHandlerIP17_cl_command_queueE7releaseES3_]+0x14): undefined reference to `clReleaseCommandQueue' collect2: error: ld returned 1 exit status
after the program defaults to OpenCL2.0.
I've done some poking around and believe that I haven't installed the SDK properly, or at the very least haven't linked it correctly, though I'm not familiar enough with bash commands to make any sense of what I'm supposed to do through it. Thanks in advance.

Hi TraceV,
Can you share your linker command? If your ocltest.cpp source is appropriate for sharing... can you start a new thread on the forum and attach it?
Edits:
Thanks for the comment. This looks like the OpenCL library isn't being linked in properly.
On Linux OS the linker will need to see libOpenCL.so... On Windows OS the linker will need to see OpenCL.lib... both are available from the Intel SDK for OpenCL Applications 2017 and 2019 beta respectively.
Adding -lOpenCL -L<path to libOpenCL.so> may get you across the finish line.
Also... Look out for deprecated functions when using OpenCL 2.0 which may not link as expected without the usage of macros... Some functions only exist for OpenCL 2.0 while some exist in 1.2 but are sometimes exposed with #define CL_USE_DEPRECATED_OPENCL_1_2_APIS... Examples that users evaluate may not specify which OpenCL version they expect, so a developer needs to consider tweaking the code in accordance with their platforms.
/Edits
Thanks for your interest,
