JuliaCon 2022 (Times are UTC)

The JuliaMolSim community is open to anyone who uses/develops Julia code that is used for simulating/analyzing systems that are resolved at the level of atomic/molecular coordinates. You can learn more about the packages we maintain and join conversations on our Slack workspace by going to our website at https://juliamolsim.github.io .

Our BoF session from JuliaCon 2021, “Building a Chemistry and Materials Science Ecosystem in Julia,” helped jumpstart the Slack community. A major subsequent output from those ongoing conversations was the development of the AtomsBase interface, defining a common set of functions for specifying atomic geometries. We’re really excited about the prospect of this effort enabling great interoperability between different types of simulation and analysis as well as to share code for tasks like visualization and I/O. In fact, it already has begun to have this impact in a number of academic projects with international collaborators and funded by major agencies such as the US Department of Energy. A major part of the strength and impact of these efforts has been substantial investment of effort from the beginning by mathematicians, computer scientists, and domain scientists working together, a hallmark of the Julia community writ large and a major part of the reason we’re building this community in Julia.

This year, we’re hosting a minisymposium to keep the community going strong, make new connections, show off cool projects, and collect new ideas! Our planned agenda (so far!) is as follows:

1. Introduction to JuliaMolSim in general and AtomsBase in particular with brief showcase of packages adopting the interface so far
2. Some “deeper-dive” talks on packages now using AtomsBase, focusing on updates since last JuliaCon and also elucidating other emerging themes such as support for automatic differentiation (AD) and GPU utilization
   1. Chemellia machine learning ecosystem (Rachel Kurchin)
   2. Molly.jl particle simulation package (Joe Greener)
   3. DFTK.jl density functional theory package (Michael Herbst)
   4. CESMIX project (Emmanuel Lujan)
3. Other contributed talks from the JuliaMolSim community, including:
   1. Fermi.jl (Gustavo Aroeira)
   2. ACE.jl (Christoph Ortner)
   3. NQCDynamics.jl (James Gardner)
4. “Quick pitch” session: what’s the next community project a la AtomsBase? Pitch your idea and find collaborators! (If you are interested in pitching, contact the minisymposium organizers and we will be in touch with more details). Some example topics could include:
   1. Plotting recipes (e.g. in Makie) for AtomsBase systems
   2. An ab initio MD engine based in Molly, utilizing DFTK for energy/force calculations via AtomsBase
