I get the sense that the intention is there to make it a complete implementation, it just isn’t finished yet. Which is what I’m planning on doing next: starting with the matrix functions.

I would also add that the provided rend_lib.cu doesn't define some functions required when evaluating textures (for example osl_texture_set_swrap_code(...) and osl_texture_set_twrap_code() were missing). So, as far as I can tell, one has to modify this lib to support such features, and it thus becomes impractical to use the one provided in the examples. To me, providing the rend_lib as an llvm bitcode to OSL seems completely unnecessary.
It would be interesting to know why this choice was made in the first place.
