clInfo is a small tool to obtain information about OpenCL support. It will gather information about all devices from all platforms. The code generates an in-memory property tree, which can be also easily exported as it consists of C data structures -- making this tool perfect for embedding into other projects.
There is also a GUI built on top of clInfo, which you can download here. The GUI requires a 64-bit Windows 7 or later.
The source code can be retrieved from the public repository.
