opencl

I downloaded the AMD APP 3.0 SDK and as soon as I include #include <CL/cl.hpp> into my cpp it throws deprecation warnings: 1>c:\program files (x86)\amd app sdk\3.0\include\cl\cl.hpp(4240): warning C4996: 'clCreateSampler': was declared deprecated and many more. Am I doing something wrong? I feel uncomfortable starting to play with openCL having so many warnings already before writing a single line of useful code. The issue here is that cl.hpp is for OpenCL 1.X platforms, but the rest of AMD's SDK supports OpenCL 2.0. The clCreateSampler function was deprecated in OpenCL 2.0. Khronos have

After searching a lot for solutions to this problem, I found that this particular error has not been documented properly for Windows. So I have decided to post this issue along with the solution. Sorry if I am posting this in the wrong section. I hope this solution will help users with the PyOpenCL installation error in the future. Please note that the examples used here are for ATI Radeon GPUs that supports the AMD OpenCL SDK SDK. For other GPUs , please refer to their respective parameters and implement them as necessary. Also do not attempt to install using pip if the installation fails.

I am using NVIDIA's GeForce GTX 480 GPU on Wwindows 7 operating system on my ASUS laptop. I have already configured Visual Studio 2010 for CUDA 4.2. How to configure OpenCL for nvidia's gpu on visual studio 2010?? Have tries every possible way. Is it possible by any way to use 'CUDA toolkit (CUDA 4.2)' and 'nvidia's gpu computing sdk' to program OpenCL? If yes then How? If no then what is other way? KLee1 Yes. You should be able to use Visual Studio 2010 to program for OpenCL. It should simply be a case of making sure that you have the right include directories and libraries setup. Take a look

The code I used is from this question OpenCL image3d linear sampling , I've tested in 2d and 3d, both with huge diff between CPU and GPU. Here is the result of CPU: coordinate:0.000000, result: 0.000000 coordinate:0.100000, result: 0.000000 coordinate:0.200000, result: 0.000000 coordinate:0.300000, result: 10.156250 coordinate:0.400000, result: 30.078125 coordinate:0.500000, result: 50.000000 coordinate:0.600000, result: 69.921875 coordinate:0.700000, result: 89.843750 coordinate:0.800000, result: 100.000000 coordinate:0.900000, result: 100.000000 coordinate:1.000000, result: 100.000000 The

I have been looking to a way to develop openCL in Java. I found aparapi interesting as it focusses on parallelization but creates openCL code as well. As I understand it the code will run with or without a GPU but still run parallized. My trouble is: where can I find documentation on how to install what? The AMD site was often pointed at, but it contains no information about aparapi, I wondered as well whether their code will work on Nvidia cards. The links to Google code is obsolete and the Github site is neither very helpful. A pointer to some more documentation is very much appreciated. As

Given the following structure typedef struct { float3 position; float8 position1; } MyStruct; I'm creating a buffer to pass it as a pointer to the kernel the buffer will have the previous buffer format. I understand that I've to add 4 bytes in the buffer after writing the three floats to get the next power of two (16 bytes) but I don't understand why I've to add another 16 bytes extra before writing the bytes of position1. Otherwise I get wrong values in position1. Can someone explain me why? A float8 is a vector of 8 floats, each float being 4 bytes. That makes a size of 32 bytes. As per
