《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malloc()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...

To enable cuda-gdb for samples builds, define theENABLE_CUDA_DEBUGflag on the CMake command line. For example: cmake -DENABLE_CUDA_DEBUG=True ... Platform-Specific Samples Some CUDA samples are specific to certain platforms, and require passing flags into CMake to enable. In particular, we...
CUDA编程允许你的程序执行在异构系统上,即CPU和GPU,二者有各自的存储空间,并由PCI-Express 总线区分开。因此,我们应该先注意二者术语上的区分: Host:CPU and itsmemory (host memory) Device: GPU and its memory (device memory)) 代码中,一般用h_前缀表示host memory,d_表示device memory。

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...
This example extends the previous one to add two vectors together. For simplicity, assume that there are exactly the same number of threads as elements in the vectors and that there is only one thread block. The CU code is slightly different from the last example. Both inputs are pointers,...
