Simple python script to obtain CUDA device information
#!/usr/bin/env python
# -*- coding: utf-8 -*-
Outputs some information on CUDA-enabled devices on your computer,
including current memory usage.
It's a port of
from C to Python with ctypes, so it can run without compiling anything. Note
that this is a direct translation with no attempt to make the code Pythonic.

# This patch is required:
# For: google authentication.
# When: Running rails on a port other than 80 where a proxy server proxies to rails.
# Cause: 1. Rack is not able to figure out that it should not set the realm url port to the rails custom port in case the full_host is mentioned using
# OmniAuth.config.full_host
# 2. OpenID tries to validate the incoming callback url with the custom port that rails is running on and throws the error "return_to #{meth.to_s} does not match".
