Hi.
I'm a programmer from Russia with strong skills in C++. You can see the full list of my skills on my profile page. I'm good with version control systems, I worked with Git and Bazaar, but I'm able to learn other systems as well. My knowledge in this field includes simple actions like staging changes, commiting them to a local repository, pushing them to a remote one, merging changes, branching, and more complex actions like resolving the conflicts etc.
As for your project, I think, it needs profiling, maybe some system calls require too much time. Or perhaps, we can use CUDA or similar libraries.
If you're interested, feel free to contact me.
All the best,
Sergey.
