The difference … WebFeb 4, 2012 · The code is compiled correctly, it is the Visual Intellisense which is trying to parse the code and catch errors on its own. The trick I do usually is to have a "hacked" header file which defines all CUDA-specific symbols ( threadIdx, __device__, etc.) and then include it in the .cu file like this: #ifndef __CUDACC__ #include "myhack.h" #endif.

WebthreadIdx, blockIdx, blockDim and gridDim are special objects provided by the CUDA backend for the sole purpose of knowing the geometry of the thread hierarchy and the position of the current thread within that geometry. These objects can be 1D, 2D or 3D, depending on how the kernel was invoked. Webgrid_size→gridDim(数据类型：dim3 （x，y，z）); block_size→blockDim; 0<=blockIdx
