Answer 1

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

Answer 2

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.
