OpenCL 1.0 adds support for double precision floating-point as an optional extension. An application that wants to use double will need to include the #pragma OPENCL EXTENSION cl_khr_fp64 : enable directive before any double precision data type is declared in the kernel code.

I'm trying use double type in openCL, but doesn't work anyway, i want use double for more precision, if have any other type make this, please, tell me. if you don't have time for read my code, resuming is: I want use double(or other type) in openCL for more precision in calculation of pi. My code:

What’s precise enough? Support for double precision floating-point type double in OpenCL kernels requires an extension. AMD provides cl_khr_fp64 for newer high-edn hardware, but also a non-fully compliant cl_amd_fp64 extension for other hardware.NVIDIA and Intel support the cl_khr_fp64, so no exceptions need to be made for those drivers.

Dec 12, 2017 · For my kernel, I need double precision. In CUDA, this is no problem, it is automatically supported. However, in order to support non NVIDIA hardware, the user should be able to use OpenCL, too. Here, as far as I understand, double precision has to be activated manually. Currently, the compiler throws the exception

Sep 10, 2009 · No double precision support?! It would be useless for many if not most scientific computation. I have read through nVidia's OpenCL documents. My impression is that double precision is supported on GPUs with 1.3 computing capability.

Jan 05, 2013 · Yes, OpenCL 1.2 supports double precision. Whether or not your device does is another question. ... On the host side, you need to check if the device has double precision support. I think earlier posts answer that. ...

I am programming in OpenCL using a GeForce GT 610 card in Linux. My CPU and GPU double precision results are not consistent. I can post part of the code here, but I would first like to know whether anyone else has faced this problem.

Now that the Haswell NDA has been lifted, I wanted to know 1. Do any of the GPUs (Iris Pro 5200, Iris 5100, HD 5000, HD 4600) support cl_khr_fp64 (or perhaps some custom fp64 extension) in OpenCL? 2. If they do, what speed can we expect? 3. If they don't support fp64 in OpenCL, do they support fp64 in some other GPU compute API? Ivy Bridge used to provide limited fp64 support (add and mul, but ...

Optional Double Precision and Half Floating Point. OpenCL 1.0 adds support for double precision and half floating-point as optional extensions. The double data type must confirm to the IEEE-754 double precision storage format.. An application that wants to use double will need to include the #pragma OPENCL EXTENSION cl_khr_fp64 : enable directive before any double precision data …
