Intel OneAPI Basic Toolkit installation problems

[janez-makovsek]

Dear Sir,

When installing the latest version of Basic Toolkit (comprehensive), this causes two problems with Open CL drivers:

1.) For 32bit applications, which rely on Open CL, but have nothing to do with Intel, crash after the installation of the Basic Toolkit. 

Exception happens inside of the

clGetPlatformIDs

and the exception code is:

C06D007E

The 32bit OpenCL driver subsystem appears permanently broken for all platforms. Any idea how to recover?

2.) For 64bit applications, there are three platforms:

a.) Intel(R) OpenCL, returns an error when calling:

clCreateContextFromType

The error reported is "out of memory" for the CPU device.

b.) The FPGA emulation platform, which has one device

c.) The FPGA SDK, which has no devices.

The machine on which the installation was made does not have an Intel GPU, but it does have AMD and NVidia devices.

Temporary workaround to resolve both problems, rename "Khronos" to "whatever" in the following registry entries:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\KhronosX\OpenCL
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KhronosX\OpenCL

Then all other OpenCL drivers (AMD and NVidia) continue to work fine.

But  I am still curious, why would 32bit clGetPlatformIDs call fail with internal exception, when Intel drivers are present?

Thanks!

Hi Janez, could you share the link of the website from where you had downloaded the Intel® oneAPI Basic Toolkit?

We would like to know.

Janez, could you share the log files with us in this scenario? The default location for the log files on Windows would be> C:\Program Files (x86)\Intel\oneAPI\logs

Janez, we have contacted you privately regarding your query. Please check your inbox for further updates.

Hi Janez,

​From your description, I think you install the Base toolkit, so you install Intel OpenCL CPU runtime. And you don't have Intel GPU, but have AMD and NVidia GPU. My question is which device that your application run on? Is on GPU or CPU?

Thanks​

Considering that

> 32bit clGetPlatformIDs call fails with internal exception

>64bit returns an error when calling clCreateContextFromType

these errors happen before you select the device with OpenCL, I dont understand your question.

If the code could reach the point where any OpenCL device becomes accessible, then it could also run on any Open CL device.

Kind Regards!

Hi,

Sorry for the delay in replying. To figure out your issue, could you provide us with the following information?

1 . The content of the following paths

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\KhronosX\OpenCL

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KhronosX\OpenCL

2 . The value of OCL_ICD_FILENAMES

We want to check if any older versions of OpenCL CPU RT is installed on your machine.

Thanks
