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

In the documentation for CUDA 6.5 has written: http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#ixzz3PIXMTktb 5.2.3. Multiprocessor Level ... 8L for devices of compute capability 3.x since a multiprocessor issues a pair of instructions per warp over one clock cycle for four warps at a time, as mentioned in Compute Capability 3.x. Does this mean that the GPU Kepler CC3.0 processors are not only pipelined architecture, but also superscalar? Pipelining - these two sequences execute in parallel (different operations at one time): LOAD [addr1] -> ADD -> STORE [addr1] -> NOP NOP ->

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 have used atomicMax() to find the maximum value in the CUDA kernel: __global__ void global_max(float* values, float* gl_max) { int i=threadIdx.x + blockDim.x * blockIdx.x; float val=values[i]; atomicMax(gl_max, val); } It is throwing the following error: error: no instance of overloaded function "atomicMax" matches the argument list The argument types are: (float *, float) . The short answer is no. As you can see from the atomic function documentation , only integer arguments are supported for atomicMax and 64 bit integer arguments are only supported on compute capability 3.5 devices.
