[GRASS-dev] Interested in parallelization of GRASS

[Maris Nartiss]

Hello,
as nobody has answered Your mail, I would drop my 0.02$.

As most of current GRASS is designed with single process single thread
short-lived CLI applications in mind. Redesigning core of GRASS to
take advantage of modern multi-core CPUs and/or nodes /GPUs would be a
nice thing. You can read about current state of GRASS parallelization
at WIKI [1].

Keep in mind that GRASS mostly is written in C and there are no plans
to change core language to anything else.

There are many areas that could benefit from thread-safe/parallel
processing: vector and raster reading/writing, OGSF etc.

As I'm not a (good) programmer, I can't help You more. Feel free to
explore existing codebase [2] and documentation [3], [4].


Maris.
