SEA Panel Discussion on Language Interoperability

The UCAR Software Engineering Assembly will hold a panel of lightning talks followed by a discussion on language interoperability at 3 PM MT on Wednesday February 26, 2025.

The discussion can include more traditional Fortran-C/C++ interoperability, but we're especially interested in interoperability of compiled codes with interpreted languages such as Python and Julia. For example, the Earth System Modeling Framework (ESMF) team is considering building out capabilities to facilitate the coupling of model components written in Python or Julia with those in Fortran, C and C++.

We currently have the following panel speakers, who will present ~5 minute lightning talks on related experiences and perspectives:

  • Bill Sacks - thoughts on prospective ESMF capabilities to facilitate the coupling of model components written in Python and Julia with C/C++/Fortran code
  • Kyle Shores - team maintains a lot of C++ code with C interface exposed for Fortran and Python interoperability
  • Orhan Eroglu - GeoCAT experiences leveraging Python-Fortran (via f2py) and Python-C++ (via Cython) interoperability

There is still room for 1-2 more panelists, so please reach out to the SEA committee if you may be interested. If you are NCAR/UCAR staff, you can use this calendar link to save this event. If you are external to the organization but wish to attend, contact our admin team for a registration link.

Participate in an upcoming SEA event on language interoperability

The UCAR SEA is planning to have a discussion, with a few short presentations, on the topic of language interoperability, providing an opportunity for groups to share their experiences and plans in this area. This can include more traditional Fortran-C/C++ interoperability, but we're especially interested in interoperability with other languages such as Python and Julia.

For example, the Earth System Modeling Framework (ESMF) team is considering building out capabilities to facilitate the coupling of model components written in Python or Julia with those in Fortran, C and C++.

We are looking for volunteers to give microtalks on the subject. Do you have experience with this kind of language interoperability that you would be willing to share in a short (~ 5-minute) presentation or through participation in a discussion session on this topic – sharing successful techniques, challenges you’ve encountered, etc.? Or does your group have plans to add capabilities in this area that you would be willing to share?

If so, please contact Brian to discuss how you can get involved.
