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:

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 …

Mar 17, 2019 · Perhaps the standard can force some type of emulation mode be supported, or return an error if double is not supported by the OpenCL device. Querying device capabilities for double is also an option. Please let me know when double support is planned for OpenCL, or if the standard may be revised to include it in this iteration.

Mar 25, 2010 · I try to transform float to double in my simple program that only makes a product of one array and a value. It works fine with float but when I pass it to double, results are wrong. This is my kernel: [codebox]#pragma OPENCL EXTENSION cl_khr_fp64: enable __kernel void VectorMul(__global const double* a, double b, __global double* c, int ...

Jan 05, 2013 · Yes, OpenCL 1.2 supports double precision. Whether or not your device does is another question. You can query your device to test this. Page 39 onwards of the OpenCL 1.2 Specification: www.khronos.org/registry/cl/specs/opencl-1.2.pdf If double precision is not supported, CL_DEVICE_PREFERRED_VECTOR_WIDTH_DOUBLE must return 0.Reviews: 13

NVidia has support for OpenCL 1.1 since drivers 280.13, so if you need OpenCL 1.1, then make sure you have this version or later. ... If you have a 8 core processor with double threading, then it mostly is understood that 16 pipelines of instructions are possible. OpenCL takes care of this threading, but also uses parallelism provided by SSE ...

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 type is declared in the kernel code.
