Classes
class	viennacl::ocl::backend< dummy >
	A backend that provides contexts for ViennaCL objects (vector, matrix, etc.) More...

Namespaces
	viennacl
	Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.
	viennacl::ocl
	OpenCL backend. Manages platforms, contexts, buffers, kernels, etc.
