I wrote an OpenCL program to convert Laititude-Longitidue to UTM coordinates. I am using an Nvidia gtx285 with 190.89 driver and CUDA 2.3. When I use ‘#pragma OPENCL EXTERNSION cl_khr_fp64 : enable’ I get an unsupported extension error which basically tells me OpenCL doesn’t know how to deal with doubles. Does anyone know if I need an updated driver or does current Nvidia drivers not support double precision in OpenCL? Thanks.
I have the same problem. That is I can not use double precision. When I write #pragma OPENCL EXTENSION cl_khr_fp64 : enable
to the kernel source code, I get following error
error: unsupported extension used with ‘#pragma OPENCL EXTENSION’ #pragma OPENCL EXTENSION cl_khr_fp64 : enable
Hi, I want to buy a GPU card that supports double precision for OpenCl.
I want to spend around 300 Euro.
I am considering buying GeForce GTX 285. It is stated that
it has 1.3 Compute capability. Does this mean that all the
GeForce GTX 285 cards sold such as in this site
will have double precision support?
If you can help I appreciate.
