问题描述
我可以使用PTX文件中包含的PTX函数作为外部设备函数来将其链接到另一个应调用该函数的.cu文件吗？
Can I use a PTX function contained in a PTX file as an external device function to link it to another .cu file which should call that function?
这是中的另一个问题，其中函数本身不包含在。 cu文件，但我宁愿以某种方式链接PTX功能。
This is another question from CUDA - link kernels together where the function itself is not contained in a .cu file but I rather have a PTX function to be linked somehow.
推荐答案
您可以自己加载包含PTX代码的文件 cuModuleLoad 和 cuModuleGetFunction 来自文件系统的代码，如下所示：
You can load the file containing PTX code in your own code from the filesystem by cuModuleLoad and cuModuleGetFunction as follows:
CUmodule module;
CUfunction function;
const char* module_file = "my_ptx_file.ptx";
const char* kernel_name = "my_kernel_name";
err = cuModuleLoad(&module, module_file);
err = cuModuleGetFunction(&function, module, kernel_name);
您也可以将PTX代码直接作为字符串传递给CUDA驱动程序，请参见。
You can also pass the PTX code to the CUDA driver directly as a string, see Passing the PTX program to the CUDA driver directly.
