Dependency Analysis

Please note that this analysis is highly experimental. The aim here is to make maintenance easier by inspecting the package's dependencies. Importantly this analysis does not support optional dependencies, please double check those before making changes. If you do not want hinting of this kind ever please add bot: inspection: false to your conda-forge.yml. If you encounter issues with this feature please ping the bot team conda-forge/bot.

Analysis by source code inspection shows a discrepancy between it and the the package's stated requirements in the meta.yaml.

Packages found by source code inspection but not in the meta.yaml:

• cython

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@minrk @isuruf Folks, in this update, I'm adding support for Intel MPI (Linux and Windows). However, I believe the Intel MPI support in conda-forge is still a bit precarious.

• We have the two packages impi-devel and impi_rt, but these packages are not proper MPI providers, in the sense that they are coming almost verbatim from the Intel channel, and there is no proper dependency on the mpi metapackage.
• We do not have impi-mpi{cc|cxx|fort} packages to pull in the compilers.

[dalcinl]

On top of my previous comments, it seems that the compiler wrappers are not usable as they are, because they do not use the compiler commands from the compiler package.

Another caveat: Intel MPI does not provide mpifort, but mpifc.

@conda-forge-admin, please rerender

[dalcinl]

I'm merging this as it is now. I'm a bit worried the new Intel MPI builds may somehow mess the conda solver.

@jan-janssen If you see any regression in production, let me know ASAP.

@dalcinl So far everything works fine for mpich but my openmpi tests fail. I am going to look into this in more detail https://github.com/pyiron/pympipool/pull/181 . To be more precise the issue appears for Python 3.9 and 3.10 but it does not appear for 3.11.
