How to run the example with add.cubin file?

[VariniChiara]

I'm trying to run the example with the add.cubin kernel but it seems not to work.

I've tried
"...
let module_data = CString::new(include_str!("../add.cubin"))?;
let module = Module::load_from_string(&module_data)?;
..."

but I got
error: src/../add.cubin wasn't a utf-8 file

the I've tried
"...
let filename = CString::new("./sub.cubin")?;
let module = Module::load_from_file(&filename)?;
..."
but I got
Error: InvalidSouce

That's a fair point! I don't know, I've only ever used PTX files.

include_str! won't work with binary files. I always meant to create an include_cstr! macro if I could figure out how to implement it, but never got around to it.

Using load_from_file is probably the right way to go, but you'll need to make sure your path is correct. If you're using relative paths, then I think they'll be relative to the current working directory when you run the program.

Unfortunately even the load_from_file() doesn't work even if I set the correct path,
Is there a workaround?

I'm successfully using load_from_file to load a fatbin. You can generate a fatbin by passing '-fatbin' to nvcc.

How are you compiling the binary?

I tried to use nvcc-fatbin add.cu to compile the file using load_from_fiile to load. Error NoBinaryForGpu
Can you directly load the CU file to call
