How do I get a PTX file to execute

I know how to generate a .ptx file from a .cu and how to generate a .cubin file from a .ptx. But I don't know how to get the final executable.

More specifically, I have a sample.cu file, which is compiled to sample.ptx. I then use nvcc to compile sample.ptx to sample.cubin. However, this .cubin file cannot be directly executed without host code. How can I link .cubin file to my original .cu file to produce the final executable?

Solution

  • You should be able to run ptx code directly from the cuda driver api with cuModuleLoadDataEx. There is an example here at page 5
