where can I find the macro

[bigbenbird]

Are there any macors in cuda?And where can I find a list of them.Such as the macors defines the maximum threads per block.

There are compiler macros defined by NVCC. These include NVCC, CUDACC, and CUDA_ARCH. These are discussed in the CUDA Compiler Driver NVCC document ([url]NVCC :: CUDA Toolkit Documentation).

Compute capability limits such as maximum threads per blocks are queried through cudaDeviceGetAttributes and cudaGetDeviceProperties and are not available as macros. For more information see the CUDA Runtime API [url]CUDA Runtime API :: CUDA Toolkit Documentation.

CUDA C Device code supports a number of built-in variables. These include gridDim, blockIdx, blockDim, threadIdx, and warpSize. These are defeind in the CUDA C Programming Guide section on Built-in Varaibles ([url]Programming Guide :: CUDA Toolkit Documentation).

Thank You!!
