Python fastxor extension module
Afraid of red status ? Please click on the link, sometimes this is not my fault ;-)
A C++ fast XOR implementation strongly inspired by eryksun's stackoverflow post.
Here are the results on my workplace desktop computer (Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz):
| Method Name | Time | Speep-up |
|---|---|---|
| xor_inplace_loop | 0.444 | 1.000 |
| xor_list_comprehension | 0.237 | 1.877 |
| numpy.bitwise_xor | 0.00175 | 252.986 |
| fastxor.fast_xor_inplace | 0.00125 | 356.339 |
What the release number stands for ?
I do my best to follow this interesting recommendation : Semantic Versioning 2.0.0
How to install it (Python 2.7) ?
Install some packages that are not handled by pip:
sudo apt-get install gfortran python-dev python-pip
Make sure that pip is up-to-date (PIPception):
sudo pip-2.7 install --upgrade pip
Then, you only need to run setup.py:
python2 setup.py test sudo python2 setup.py install
How to install it (Python 3.3) ?
Install some packages that are not handled by pip:
sudo apt-get install gfortran python3-dev python3-pip
Make sure that pip is up-to-date (PIPception):
sudo pip-3.3 install --upgrade pip
Then, you only need to run setup.py:
python3 setup.py test sudo python3 setup.py install
Sometimes numpy setup fails, just run sudo pip-3.3 install numpy to solve this.
How to check coverage ?
python setup.py test xdg-open tests/cover/index.html
How to use it ?
This extension module gives you access to fast_xor_inplace and fast_xor (... TODO).
