Support of the IBM Power9 (ppc64le) architecture

[raimis]

• I read the conda-forge documentation and could not find the solution for my problem there.

PLUMED has been ported to ppc64le (conda-forge/plumed-feedstock#22, conda-forge/plumed-feedstock#23).

So, we can port OpenMM-PLUMED too! @jaimergp do you foreseen any problems?

[jaimergp]

Yes, it's possible, but right now building PPC packages with CUDA support involves changing to manual feedstock maintenance (see this file at OpenMM's feedstock), and I'd rather not maintain too many feedstocks this way.

You can build it locally if you adapt this file from OpenMM's feedstock and drop it in your local copy of this feedstock. Then python build_locally.py should give you a tarball you can distribute.

If that's not a viable solution, we can discuss it further but I can't promise much.

Thanks @jaimergp, I will try the manual solution to test.

When we will be able to build the PPC packages with CUDA properly? Is any issue to check the progress?

[jaimergp]

I'd say it has to do with the CentOS 8 issue here: conda-forge/conda-forge.github.io#1432

[raimis]

@jaimergp any updates on this?

[jaimergp]

Nothing new. There's a solution we can try and I am going to put some time there, we'll see how it works in practice. conda-forge/cudatoolkit-feedstock#64
