Final Call for Participation: PROPL 2026 (Workshop on Programming for the
Planet)
Monday 15th June 2026
co-located with PLDI'26, Boulder, Colorado
https://urldefense.com/v3/__https://pldi26.sigplan.org/home/propl-2026__;!!IBzWLUs!SUFji4ZSuuChJelJ0uT387W5RJe4ioMUZ6j2y0U66l1eiCKdestcPXXqkbNhOqCvKNTj1sOjIhVOLPE_mamkwk8gseAf6zWEFjk$
There are simultaneous interlinked crises across the planet due to human
actions: climate change, biodiversity loss, and desertification
(collectively, a crisis in climate health). Assessing progress on these
complex and interlocking issues requires a global view on the effectiveness
of our adaptations and mitigations. To succeed in the coming decades, we
need a wealth of new data about our natural environment that we rapidly
process into accurate indicators, with sufficient trust in the resulting
insights to support interventions that affect the lives of billions of
people worldwide.
Previous editions of PROPL
(https://urldefense.com/v3/__https://propl.dev/__;!!IBzWLUs!SUFji4ZSuuChJelJ0uT387W5RJe4ioMUZ6j2y0U66l1eiCKdestcPXXqkbNhOqCvKNTj1sOjIhVOLPE_mamkwk8gseAf4ibsyDQ$
) have investigated the state
of practice in this area while also eliciting ambitious visions for future
computational systems designed to support collaborative climate analysis,
modeling, forecasting, policy, and diplomacy. Inspired by the lively
discussions around these future visions in previous years, PROPL 2026 will
be more focused, operating as an open working meeting where we elicit
requirements and propose a coherent set of technical approaches for a
next-generation planetary compute engine, i.e. a large-scale _live
computational commons_ where all sorts of humans, working together when
appropriate with safely sandboxed AI systems:
* collect and process billions of observations about the state of the
planet, with new data being ingested continuously
* feed this data into live computations, including data analyses and
simulations
* present the results of these computations in formats that are
comprehensible and actionable in the real world
**Participation**
This 3rd "Action PROPL" now invites anyone with an interest in helping
research, design and implement a next-generation planetary compute engine
to attend and actively participate in the workshop, including climate
science and biodiversity practitioners and researchers and engineers with
expertise in programming systems. In each topical session, the organizers
will begin with a brief orienting presentation, then ask audience members
to contribute notes and ideas to a living document before engaging in an
active discussion. If you're interested in the topic of planetary health,
but feel like your research doesn?t fit, then we encourage you to come
along and we will try to figure it out with you!
**Talks**
We also have four solicited 'position paper' talks accepted at the workshop
which will help frame the discussions:
* A Compiler-First Planetary Compute Engine: Automatic differentiable and
performance portable Earth System Modeling (William S. Moses, Gong Cheng,
Valentin Churavy, Maximilian Gelbrecht, Milan Klower, Joseph Kump, Mathieu
Morlighem, Sarah Williamson, Dhruv Apte, Paul Berg, Mosè Giordano, Chris
Hill, Nora Loose, Alexis Montoison, Sri Hari Krishna Narayanan, Avik Pal,
Michel Schanen, Simone Silvestri, Greg Wagner, Patrick Heimbach)
* Marrying engineering rigor & scientific rigor for the planet (Deepak
Cherian)
* Mind the Gap: General-Purpose Programming Languages Impede Scientific
Model Development and Communication (Dominic Orchard)
* The Basic Model Interface (BMI) (Mark D Piper, Eric WH Hutton, Gregory E
Tucker)
We hope you will join us for a stimulating and collaborative workshop!
