== Abstract ==
The current state of OpenMP support for raster modules is limited. Many of such modules can benefit from parallelization. This project aims to provide parallelization to modules chosen based on their frequency of usage and its implementation complexity.

== Bonding period report ==

1) What did I get done during this period?
- I have set up a wiki page detailing my project and its progress. (1)
- I have set up my development environment. Here's the link to my repository. (2)
- I have gotten in touch with my mentors, and we are arranging a meeting this week.

2) What do I plan on doing next week?

I will be working on parallelizing 3 modules: r.proj, r.neighbor, r.univar. Based on the results, I will adjust my plans in the future weeks.

3) Am I blocked on anything?

No, it has been good so far.
