[SoC] GSoC 2021 - Parallelization of raster modules for GRASS GIS

[Aaron Saw Min Sern]

Hi everyone,

Week 8 has concluded and here's my report for this week.

1) What did I get done this week?

r.resamp.interp [https://github.com/OSGeo/grass/pull/1771]

  *   Implement parallelization

r.slope.aspect [https://github.com/OSGeo/grass/pull/1767]

  *   Implement parallelization

Both implementation above follows similarly to r.neighbor [https://github.com/OSGeo/grass/pull/1724]. r.slope.aspect keeps track of global statistics variable like min/max, thus additional variable reduction is required aside from map computation. The benchmarking of the modules will be supplemented in the PR.

2) What do I plan on doing next week?

  *   Refactor r.univar
  *   Implement parallelization for r.series, r.patch
  *   Revisit r.proj to decide on implementation

3) Am I blocked on anything?
No major issues.

Thanks,
Aaron
