Does FABM support OpenMP?

[BeatrizArellano]

Hi all,
I noticed that FABM has (or had) an alternative branch with OpenMP support. Is OpenMP support now included in the latest FABM release, or is it expected that parallelization is handled entirely by the host model?
Thank you!

Hi, this omp branch adds support for hosts that use OpenMP for parallelization. Specifically, it ensures all FABM routines that process slices of the spatial domain are thread-safe, so they can be called simultaneousy from multiple threads. It does not make FABM do its own parallelization independently. That is still expected to be controlled by the host, typically using MPI, or now OpenMP.

NB this omp branch has not been merged into master yet.

Thanks @jornbr, that's very helpful.
