Hi everyone,
Week 1 has concluded, and this is my report for this week.
1) What did I get done this week?
r.univar
* Updated Makefile to include OpenMP dependencies
* Wrote multi-threaded test cases to ensure consistency of the program
* Wrote benchmarking script to measure speedup
* Implemented parallel support
* Drafted the PR of abovementioned changes [1]
r.neighbor
* Investigated Segment library to support random access and write opera=
tions
2) What do I plan on doing next week?
The goal is to come out with a design for output-based modules. The next st=
ep is to finish the implementation for r.neighbor. Furthermore, I plan to i=
nvestigate the thread-safety of Raster3D module for pthread implementation =
of r.mapcalc.
3) Am I blocked on anything?
No, it has been good so far, but I hope to improve on my pace.
