Re: [hwloc-devel] Python bindings for hwloc

[Guy Streeter]

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.

This is tremendous.  Thank you!

Hello
Thanks a lot!
I updated the links on the website.
Note that your code should work up to 1.11.8 except for one new topology
flag added in 1.11.6.
I am not very good at Python but I could help finishing CUDA support if
you tell me what's missing and where to look.
