How much does OpenCL and OpenCL C Programming Language cost ?
Where to buy ?
you can get implementation of OpenCL from AMD, Intel, nVidia for free.
if you want implement OpenCL standart and pass to conformance testing then you must get membership in khronos. which cost about 10000$ per year.
OpenCL is a open-spec language. You can write your own implementation for whatever hardware you like.
See http://www.khronos.org/opencl/
You can get the AMD APP SDK for free which includes the OpenCL language here:

Thanks to all for your advices !
Which components are/will be availble for 64-bit imaging from AMD
and how much do they cost?
OpenCL 1.1 ATI-Stream-v2.3 (451) gave the configuration:
1. AMD Phenom II X4 955 Processor
OK: 64-bit (although it would be useful to have each core as a CPU device
OK: cl_amd_fp64
*** cl_khr_global_in32_base_atomics
*** cl_khr_global_in32_extended_atomics
2. ATI RV770 GPU
*** address bits 32 <--- which GPU model has/will have & when 64-bits ?
3. Imaging support
*** no Image support in CPU <-- why (to run app only in CPU) / when ?
*** no Image support in GPU <-- which GPU and when ?
- does above mean lack of both 3D and 2D Image support ?
4. Double precision floating-point
*** no IEEE754-2008 fused multiply-ad <-- when ?
thanks in advance!
address bit are quite irelevant. it depend only when you want more than 4GB of memory.
image support for CPU can be enabled via env var CPU_IMAGE_SUPPORT. in APP SDK 2.4 it will be enabled most likely by default.
radeons 5xxx and 6xxx support image by default. on 4xxx card they will not support.
in upcoming 2.4 there will be support for cl_khr_fp64.
this is based on preview APP SDK 2.4 founded in beta Catalyst 11.4
