Adios2: Conda-Forge Feedstock

[ax3l]

Are you planning a conda-forge feedstock for quick installs?

Although the primary audience will barely be HPC with conda-forge, I find a conda-forge binary release quite useful for desktop applications such as HDFcompass, people writing serial python scripts on small data and CI in downstream projects.

Full disclosure: I am the current packer of the ADIOS and ADIOS-Python feedstocks for ADIOS1. (Happy to share the maintenance work.)

Hi @ax3l we don't have immediate plans or resources targeting specific package managers. That being said, we'll be very happy to work with you on a conda distribution if you're interested. Our priority is to get the December release out and have a stable cmake build backend for the C++11 library and bindings, so any package manager frontend can be then applied. BTW, package managers have become my preferred installation method. Let us know. Thanks!

Hi @williamfgc, thank you for the quick answer. That sounds great! A student of ours (@franzpoeschel) is currently starting to explore ADIOS2 in detail to make it usable in openPMD-api and with that in PIConGPU.

We will soon-ish need it in CI and CD. When we are there I will probably set up a conda-forge feedstock again and ping here for coordination. Time-scales match, that will work!

Hi @ax3l @franzpoeschel thanks for the update, looking forward to hearing about your experience with openPMD-api/PIConGPU and the conda-forge feedstock. Let us know if you have any questions. For the python scripts applications on small data, desktop apps and CI cases we built a high-level simplified API that is all write/read (sync) based for a quick jump start. For a Python example. Similarly with C++ Thanks!

Excellent, we will write the openPMD bindings against the native C++11 API and should use the ADIOS2 python API again in projects like HDF-Compass so we have a file explorer at hands.

@ax3l my bad, actually @chuckatkins has something you can start with: adios2-conda scripts

resolved in conda-forge adios2 feedstock. Thanks to @ax3l
