JustRelax.jl

How JustRelax.jl handles CPU/CUDA/AMDGPU backends — module structure, package extensions, ParallelStencil initialization rules. Use when adding/modifying kernels or anything device-related.

ParallelStencil kernel idioms and GPU-compatibility rules for JustRelax.jl, plus the Runic formatting requirement. Use when writing or editing compute kernels or any Julia source.

How to run JustRelax.jl tests — single files, the full ParallelTestRunner suite, backend selection, and MPI tests. Use whenever running or debugging tests.

Building and editing JustRelax.jl documentation (Documenter + DocumenterVitepress). Use when changing docs, docstrings, or the docs build.

How to run JustRelax.jl miniapps (benchmarks, convection, subduction) to validate solver/physics changes end-to-end. Use when verifying a physics change beyond unit tests.

Releasing a new JustRelax.jl version — version bumps, compat bumps, JuliaRegistrator, TagBot. Use when preparing or asked about a release.
