matconv-GPU 编译问题

Posted 2021-01-21 burton

如出现以下错误：

1 error detected in the compilation of "C:/Users/Justin/AppData/Local/Temp/tmpxft_00001afc_00000000-8_pooling_gpu.cpp1.ii".

则要修改上面错误中红色字体的.cu文件

在163行的函数用下面替换

// an implementation of atomicAdd() for double (really slow)
#if !defined(__CUDA_ARCH__) || __CUDA_ARCH__ >= 600
#else
__device__ double atomicAdd(double* address, double val)
{
unsigned long long int* address_as_ull = (unsigned long long int*)address;
unsigned long long int old = *address_as_ull, assumed;
do {
assumed = old;
old = atomicCAS(address_as_ull, assumed,
__double_as_longlong(val +
__longlong_as_double(assumed)));
} while (assumed != old);
return __longlong_as_double(old);
}
#endif
