Good afternoon! I need to run a program written in C++ that uses OpenCL. Before that I enabled OpenCL headers, installed CUDA (this is optional) and reinstalled Visual Studio and MinGW. I have an NVIDIA GeFOrce 1080. Well, I have an array<int, 3> loc and as a result of the execution loc should change to ..
Good afternoon! I’m trying to run code in C++ that has the following line: #include <CL/cl.hpp> But launching the program gives this error: fatal error: CL/cl.hpp: No such file or directory What have I tried to do? Completely reinstalling mingw64 Uninstalled Visual Studio 2019 and installed Visual Studio 2022 Installed NVIDIA Cuda according to the ..
I am trying to process an array of arrays of variables lengths with openCL 1.2 in c++. In each instance (workitem?) i want to process one sub array. Below I’ve tried to treat the array of arrays as a 1D array, but it does not work – random parts of the data are not processes. ..
So I just got myself a Xeon Phi and now Im wondering how could I use it with OpenCL because most of the tutorial uses OpenMP. If I change target device to the Xeon Phi and run the kernel will it work? Do I need any other library than the Intel SDK for OpenCL(v14.2). Source: ..
I am targeting OpenCL and forced to write code in C, so am really missing C++ templates. Currently doing string substitution on C sources when sending code to OpenCL compiler which is error-prone. In general, my question is how to generate C code from C++?, but out of C++ I mostly need just template instantiation ..
I can’t figure out exactly what is wrong with my code but the vadd function does not seem to work. I think it has to do with to way the kernel is created and how arguments are passed. The function does not write to any of the passed buffers. Everything compiles. const char *KernelSource = ..
In the case of cl_context and cl::Context, we can do: cl::Context context_ = cl::Context(device); cl_context context = context_(); Now, I have an OpenCL program, with the following snippet in it: … void* svm_data = clSVMAlloc(context, svm_flags, svm_buffer_size, 0); … I would like to do something similar here to what we did with cl::Context above: cl::SVMAllocator ..
I’m starting with OpenCL and would like to develop a word frequency counter from a given text. My difficulty is that OpenCL is different of anything I’ve studied in programming. I thought about making it with a map but I don’t know if it’s possible, so I put all the words in the text file ..
Maybe it is a silly question but I am really confused. I also feel so uncomfortable while using Opencl c++ wrapper functions,classes etc. The way they are explained in OpenCL c++ bindings in khronos website and the way we use them in our code looks so different to me. For example, in OpenCL C++ bindings ..
I got an error while initializing a device variable. cl::Device device; It says: "The procedure entry point clReleaseDevice could not be located in the dynamic link library OpenCL.dll". I opened OpenCL.dll from C:WindowsSystem32 with "Dependency Walker" and it really doesn’t have such a function. I’m using Windows 7 and NVIDIA CUDA Toolkit 11.5 and cannot ..
