+== Final report ==
+
+Of all the modules that are proposed to be parallelized, I have introduced OpenMP support to 8 raster modules:
+
+- r.univar - https://github.com/OSGeo/grass/pull/1634
+- r.neighbors - https://github.com/OSGeo/grass/pull/1724
+- r.mfilter - https://github.com/OSGeo/grass/pull/1708
+- r.resamp.filter - https://github.com/OSGeo/grass/pull/1759
+- r.resamp.interp - https://github.com/OSGeo/grass/pull/1771
+- r.slope.aspect - https://github.com/OSGeo/grass/pull/1767
+- r.series - https://github.com/OSGeo/grass/pull/1776
+- r.patch - https://github.com/OSGeo/grass/pull/1782
+
+The work output was lower than what was proposed as the implementation turns out the be more challenging that what I have expected.

+=== Week 9 ===
+
+'''1) What did I get done this week?'''
+
+r.univar [https://github.com/OSGeo/grass/pull/1634]
+
+- Refactor previous implementation
+
+r.series [https://github.com/OSGeo/grass/pull/1776]
+
+- Implement parallelization
+
+Implementation for r.patch is yet to be completed.
+
+'''2) What do I plan on doing next week?'''
+
+- Finish implementing r.patch parallelization
+- Write documentation on manual pages for each of the modules that have been implemented
+- Specifically, a section titled "Performance" to include user parameters for parallel processing and expected behavior and issues.
+        - r.univar
+        - r.mfilter
+        - r.neighbors
+        - r.slope.aspect
+        - r.resamp.filter
+        - r.resamp.interp
+        - r.series
+        - r.patch
+- Include a wiki page on the general OpenMP implementation and the benchmark results of each module
+
+'''3) Am I blocked on anything?'''
+
+No major issues.
+
+=== Week 10 ===
+
+'''1) What did I get done this week?'''
+
+- Finished implementing r.patch parallelization [https://github.com/OSGeo/grass/pull/1782]
+- Included a wiki page on the general OpenMP implementation [https://grasswiki.osgeo.org/wiki/Raster_Parallelization_with_OpenMP]
+- Wrote documentation on manual pages for some modules (Performance section)
+- Added benchmark scripts to all implemented modules
+
+'''2) What do I plan on doing next week and beyond?'''
+
+Most of the modules will not be merged into master by next week. There are still some checks to be done, like benchmarking and tests on large raster maps.  I intend to prepare for the GSoC submission for the next week and continue to work to smoothly prepare the PRs to be merged for the upcoming release.
