[GRASS-dev] Compilation options

[Stefan Blumentrath]

Hi again,

Seek and ye shall find...

So, there is:
https://grasswiki.osgeo.org/wiki/OpenMP#OpenMP_support_in_GRASS_7 and
https://grasswiki.osgeo.org/wiki/GPU
Which helped me a bit further.

However, my impression is that not all info there (esp. on OpenMP) is up to date (e.g. latest development like here: https://lists.osgeo.org/pipermail/grass-dev/2017-August/085711.html). Neither did it became very clear to me which modules already have robust and working support and which are just candidates or where initial implementations are available (sometimes outside the code base)...

Cheers
Stefan

Subject: [GRASS-dev] Compilation options

Dear all,

Does someone of you know which modules benefit from --with-openmp and --with-opencl compilation options?

I found this explanation of compilation options: https://grass.osgeo.org/grass72/source/snapshot/REQUIREMENTS.html
But it does not cover OpenCL or OpenMP (as well as some few more other option).

If I wanted to find out myself, could I just search the code for modules that import the relevant headers of the respective libraries?
Or is that a bit more complex?

Another question is if it would be recommended to use the different options, as I understood e.g. using --with-pthread is not necessarily a good choice...

Thanks in advance.

Cheers
Stefan
