In the New Project window, I selected Win32 as the project type and Win32 Console Application as the template. To start, I brought up the Visual C++ 2005 Express Edition IDE and clicked on the New Project button (you can also use Fileв†’Newв†’ProjectвЂ¦ from the menu). It actually takes a bit of work to do that. Then the host displays the contents of the array (line 34) and frees the array memory on both itself and the CUDA device (line 36).ДЄt this point, I have a CUDA-enabled program, but I donвЂ™t have it integrated into a Visual C++ project. This transfer is delayed until the CUDA device has finished executing the kernel, so there is no chance of getting data that has not been processed yet. Immediately after starting the kernel, the host begins a transfer of the data from the array in the CUDA device memory back to the array in the host memory (line 32). If the index is within the bounds of the array, then the corresponding array element is squared (line 13). On line 12, the array index is found by multiplying the threadвЂ™s block index (blockIdx.x) by the number of threads in each block (blockDim.x) and then adding the index of the thread within the block (threadIdx.x). Each thread is distinguished from all the others by block and thread indices that can be used to determine the array element the thread will access. In this example, each thread will execute the same kernel function and will operate upon only a single array element.

The _global_ keyword indicates that this is a kernel function that should be processed by nvcc to create machine code that executes on the CUDA device, not the host. More on nvcc, later.) Following that, the standard argument list to square_array contains a pointer to the array in the CUDA device memory and the number of elements in the array. (This information is picked up by the Nvidia compiler, nvcc, and is used when generating the instructions that start the kernel on the CUDA device. Retrieve result from device and store it in host arrayД¬udaMemcpy(a_h, a_d, sizeof(float)*N, cudaMemcpyDeviceToHost) ДЇor (int i=0 i> following the kernel name.

_global_ void square_array(float *a, int N) Kernel that executes on the CUDA device example1.cpp : Defines the entry point for the console application. It takes an array and squares each element. My first CUDA program, shown below, follows this flow.

The CUDA device operates on the data in the array.

The array is copied from the host to the memory on the CUDA device.

The host initializes an array with data.

Rob does his examples in a make-based build environment IвЂ™ll show how to build a CUDA program in the Visual C++ IDE.

ItвЂ™s a modification of an example program from a great series of articles on CUDA by Rob Farber published in Dr.

I got CUDA setup and running with Visual C++ 2005 Express Edition in my previous post.
