I looked at implementing the bindings for the CUDA driver library interfaces, and I can't see a way to add them without implementing (at least partially) Python bindings for the CUDA driver library. That's too much work for a retired person to take on. :)
The CUDA runtime library seems a bit easier. I've created a git branch called "cudart" which I hope has a proper implementation of those bindings. I can't build it because hwloc's cudart.h needs cuda.h from the CUDA driver development files, which I do not have. On an RPM based system you should be able to "make rpm". On other platforms the setup.py should build the bindings for you to try. I implemented test/cudart.py, patterned after the test/cudart.c from hwloc. --Guy On Sat, Sep 2, 2017 at 6:42 AM Jeff Squyres (jsquyres) <jsquy...@cisco.com> wrote: > Guy -- > > This is tremendous.
