<<<>>>vscode中的cuda

vscode-cpptools是否有任何方法可以抑制“ <<<>>>”错误。

我在中将“ * .cu”与“ cpp”相关联setting.json。

// use normal c++ syntax highlighting for CUDA files
  "files.associations": {"*.cu": "cpp"},

并且工作正常，除了一个问题， kernel execution configuration parameters surrounded by <<>>被误认为是错误expected an expression

dim3 dimGrid(2, 2, 1);
dim3 dimBlock(width / 2, width / 2, 1);
MatrixMulKernel<<>>(d_M, d_N, d_P, width);

任何建议

搜寻了几个小时，找不到完美的解决方案，但找到了一些解决方法。

我在这里总结：

通过编辑对CUDA文件使用普通的c ++语法突出显示setting.json

在程序中包含必要的CUDA标头

包括虚拟头以解决方法INTELLISENSE

波纹管是一个具体的例子

setting.json

"files.associations": {
    "*.cu": "cpp",
    "*.cuh": "cpp"
  }

cudaDmy.cuh

#pragma once
#ifdef __INTELLISENSE__
void __syncthreads();  // workaround __syncthreads warning
#define KERNEL_ARG2(grid, block)
#define KERNEL_ARG3(grid, block, sh_mem)
#define KERNEL_ARG4(grid, block, sh_mem, stream)
#else
#define KERNEL_ARG2(grid, block) <<>>
#define KERNEL_ARG3(grid, block, sh_mem) <<>>
#define KERNEL_ARG4(grid, block, sh_mem, stream) <<>>
#endif

    cudaFree(d_P);
}

    int elem = 100;

    float *N = new float[elem];
    float *P = new float[elem];

让我们用NVCC编译它

nvcc matrixMul.cu -Xcudafe "--diag_suppress=unrecognized_pragma" -o runcuda
