Invalid _CL_Platform error

bilal_a_1 — Thu, 24 Dec 2015 16:36:41 GMT

Hi I am trying to run OpenCL on Intel 2310 core i3 2nd generation. I have configured VS 2013(Professional) for OpenCL. When I try to create a new opencl project a message appers:

"Failed to retrieve number of devices:-32(CL_Invalid_Platform) "

But it still creates the OpenCL project.When I run a simple hello world OpenCL program.VS2013 doesn't builds it. gives following error

OUTPUT window:

1>------ Build started: Project: Opencl1, Configuration: Debug x64 ------
1> Preprocessing: OpenCLFile.cl

Hi Bilal,

Hi Bilal,

Which OpenCL release you have installed on your system?
To set the expectation right - OpenCL1.2 feature is supported on the platform you are using. Also, GPU processing is not supported on this platform. You can get details from "system requirement" section in the release notes - https://software.intel.com/en-us/articles/opencl-code-builder-release-notes. Also, would recommend you to check "known limitation" section since your system is a pretty old configuration.

Hope this information helps.

Thanks,
Surbhi

Yeah OpenCL1.2 is supported for my system.Should I use VS2015 with Intel SDK 2015 APP?

Hi Bilal,

I believe you have an outdated CPU. I don't think switching to VS2015 will help. You will need a different computer, preferably from 2012 or later. 2013 or later highly recommended.

I have the same error but

2 notes:

In my investigation of exactly this error (happened when trying to compile external OpenCL project) we've found the resolution: you should install OpenCL runtime in additions OpenCL SDK
https://software.intel.com/content/www/us/en/develop/articles/opencl-drivers.html
Actually, it is "old" SW, there is the modern and (in our opinion) preferred one:
Install oneAPI Base toolkit, select in your OpenCL project DPC++ compiler toolset, and the OpenCL project will be compiled/run as well.

Have a good luck !
