Beta2 Beta3 Beta4 which one support double precision?

Same as title.

I found beta4 doesn't support it for CPU and GPU.

No extensions are currently supported for GPU currently. There is no double support currently. In case of CPU, a device query will give you the supported extensions.

Double precision floating point is not currently supported in the OpenCL beta release. We start introducing various pieces of DPFP support in OpenCL over the next year. Some of the basic arithmetic functions will be introduced first with the math function support likely taking longer. Since full DPFP support is an optional extension in the OpenCL spec, we are concentrating first improving the performance and other aspects of the required spec first.
