• jprice: It's not clear what you are asking. Yes, you can find all of this information using clGetDeviceInfo(). If you want example code that will actually produce all of the above, then you can usually find a 'device info' sample in most OpenCL SDKs.
• DarkZeros: I don't understand, you are using a free tool to dump that information (clinfo), but you are asking for a method to do it. Why not take the code of the free tool instead? For me the question is trivial, it is answered by itself.
• user1848223: thanks for replay . that result not for me i want any tool or program to give me same info. i know about clgetdeviceinfo but can i find complete opencl program for that

Answer 1

Take at look at the Intel OpenCL SDK

There's an app they provide called "Basic Capabilities" that lists most of what you're looking for. Each app even comes with a PDF users guide. Near the back the users guide has a section called "Controlling the Sample" which lists command-line options for the app.

One of the command line options is <PLATFORM>. The apps default to looking for "Intel" hardware but I've specified the platform as "NVidia" and things worked for me.

Answer 2

There's an app called GPU Caps viewer which will show the capabilities of all the OpenCL devices available in your system.
