Hi everyone,
Week 2 has concluded, and this is my report for this week.
- What did I get done this week?
r.univar
- Address changes for the PR [1] , e.g. to use a standard option “nprocs” will now be a parameter for users to indicate the number of threads
r.neighbor
- Write test cases for parallel execution
- Drafted a PR alongside its implementation [2]
r.proj
- Write new test cases for the modules [3]
- What do I plan on doing next week?
I have managed to come up with a way to parallelize output-based modules like r.neighbor. The idea is to make use of a temporary segment file to allow threads to perform random write operations, which is not possible directly on compressed raster format file without using intermediate cache. With this design in mind, I intend to continue to parallelize similar modules next week. Also, there may be ideas in discussion to encapsulate a benchmarking framework possibly under grass.benchmark as this will be used repeatedly in the future to measure performance.
- Am I blocked on anything?
No, it has been good so far.
Warmest regards,
Aaron
