opencl

I am using Eclipse as an editor for OpenCL and I turned on syntax highlighting for *.cl files to behave like C++ code. It works great, but all my code is underlined as syntax errors. Is there a way that I can have my syntax highlighting and turn off the errors/warnings just for my *.cl files? First, the Eclipse syntax highlighter is programmed to the grammar of C and C++, and not OpenCL, so it is unaware of the syntactic extensions of OpenCL, such as New keywords New data types I suggest that the new keywords can be conditionally defined to nothing e.g. #define __kernel #define __global and

I had the following code, which works well on a machine but I when I try to run it on another machine with better graphics card I am getting errors: global[0] = 512; global[1] = 512; local [0] = 16; local [1] = 16; ciErrNum = clEnqueueNDRangeKernel(commandQueue, myKernel, 2, NULL, global, local, 0, NULL, &event); Errors: Error @ clEnqueueNDRangeKernel: CL_INVALID_KERNEL_ARGS Error @ clWaitForEvents: CL_INVALID_KERNEL_ARGS Any idea what is the problem? sharpneli How large are the buffer objects you are passing? __constant arguments are allocated from separate memory space and not from global

I am new to OpenCL. Working on a Core i5 machine with Intel(R) HD Graphics 4000, running Windows 7. I installed the newest Intel driver with support for OpenCL. GpuCapsViewer confirms I have OpenCL support setup. I Developed a simple HelloWorld program using Intel OpenCL SDK. I successfully compile the program but when run, it crashes upon call to clGetPlatformIDs() with a segmentation fault. This is my code: #include <iostream> #include <CL/opencl.h> int main() { std::cout << "Test OCL without driver" << std::endl; cl_int err; cl_uint num_platforms; err = clGetPlatformIDs(0, NULL, &num

I've just started working in opencl and I'm currently working on what should be a relatively basic hello_world program in opencl. Unfortunately the program is not outputting the proper phrase or anything at all it instead hangs with no output. Any idea on why that is the case? Below is: openglsource.cpp and hello.cl #define CL_USE_DEPRECATED_OPENCL_2_0_APIS #include<CL/cl.hpp> #include<iostream> #include <fstream> int main() { std::vector<cl::Platform> platforms; cl::Platform::get(&platforms); auto platform = platforms.front(); std::vector<cl::Device> devices; platform.getDevices(CL_DEVICE

In my kernel it is necessary to make a large number of random accesses to a small lookup table (only 8 32-bit integers). Each kernel has a unique lookup table. Below is a simplified version of the kernel to illustrate how the lookup table is used. __kernel void some_kernel( __global uint* global_table, __global uint* X, __global uint* Y) { size_t gsi = get_global_size(0); size_t gid = get_global_id(0); __private uint LUT[8]; // 8 words of of global_table is copied to LUT // Y is assigned a value from the lookup table based on the current value of X for (size_t i = 0; i < n; i++) { Y[i*gsi+gid]
