所谓CUDA与OpenGL的交互,其实就是,以前我们在cpu中开辟内存,再复制到gpu中,计算每个像素的值,再将位图传回cpu中。现在是用opengl在GPU中开辟内存,cuda对这块内存进行操作,然后再由opengl绘制显示。
要编译某个代码,请使用 CUDA C 的官方编译器 nvcc,在和代码处于同一目录时使用命令: nvcc <code-name>.cu -o <bin-name> 第一个程序hello_world.cu长得和 C 语言没有区别,它旨在告诉你 CUDA C 是 C 语言的超集。在第二个程序simple_kernel.cu中,它加入了一个由__global__修饰符(qualifier)开头的空...

The following C++ example code shows usage: #include <iostream> #include "/usr/local/cuda-14.0/bin/nv_decode.h" using namespace std; int main(int argc, char **argv) { const char* mangled_name = "_ZN6Scope15Func1Enez"; int status = 1; ...
For example, you can type CUDART.lib; instead of the longer $(CUDAToolkitLibDir)\CUDART.lib. Figure 2.10: CUDA Runtime Library Now that we have added the include path and the runtime library, we are ready to write some CUDA code. Initially, we can test that the Include directory and ...

《CUDA By Example》中文译名《GPU高性能编程CUDA实战》是研究GPGPU异构并行计算非常不错的工具书。书中给出的代码,非常个别的地方有失误,但是都有人为标注了,而且对不同的编程工具可能需要自己配置链接库。压缩包包括中文版的和英文版的,还有代码和库。

Each of these streams is defined by the following code sample as a sequence of one memory copy from host to device, one kernel launch, and one memory copy from device to host: Each stream copies its portion of input array hostPtr to array inputDevPtr in device memory, processes inputDev...
