《CUDA by Example》--chapter10 code 先来介绍CUDA中的一个函数:cudaHostAlloc(),理解这个函数,要和标准C语言中的()联系起来。malloc()函数是CPU在主存中开辟内存并返回指针,而cudaHostAlloc()是cuda在主存中开辟指定内存并返回指针。cuda开辟和CPU开辟的主存有什么不同?CPU是分配可分页的(Pagable)主机内存,而cu...

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)开头的空函数,这类函数我们称之为核函数(kernel function)。核函数由 CPU 调用,GPU 运行,相当于...
