floating-point computation capability

--- Quote Start ---

Support for double precision is limited but this is independent of scalar versus vector support. The double precision floating point operators and math functions are not fully conformant with the 1.0 OpenCL spec but you can still use them.

So, do we currently support for double precision floating point format in vector operations? Since the programming guide doesn't specifically point out AOC supports it or not.. (or perhaps I overlooked the spot) so I got confused a little bit.

thank u.

Please see Appendix B of the programming guide (http://www.altera.com/literature/hb/opencl-sdk/aocl_programming_guide.pdf) for details on floating point (and double precision) support and conformance.

Thank you. I've read this before posting questions.

In table 6, in the scalar data types, it says AOC supports for the double precision FP format. In the vector data types, it only say it starts to support for, for instance, ucharn, where n equals to 3. So to my understanding, I think it means AOC conform with the v1.0 specification's supports to double FP in the built-in vector types, which means AOC currently doesn't support double FP in built-in vector types.

Am I correct? Thanks.

Double precision floating point vector types should be supported. You could try writing a quick kernel to validate this.

Thank you for your reply.

The board is not arrived yet, that's why I asked question here... May I ask, are you an Altera technical for OpenCL or a developer? I really appreciate an accurate answer for my question.

Thanks.

Never mind. I will find it out and post the results here. Thanks for the suggestion.
