solprop.backends

Execution backends behind one seam.

The NumPy reference, Numba CPU and native backend (docs/dev/backends.md). This package exports the seam itself — the Backend protocol and the record types it returns — and solprop.backends.registry, which selects a backend by name and says why one is not usable.

Modules

batch	Establish fixed-schedule lockstep with independent backend workspaces.
bodies	Per-element mathematics, written once and compiled for each backend family.
driver	The step loop every backend runs, with the kernels left abstract.
exponential	The phi functions and exponential Adams weights, in NumPy (SEP 16 sections 4.2-4.3).
low_storage	The low-storage interaction-picture RK4 march: replay-only, accepted in place.
memory	Estimate a run's persistent memory before a backend allocates it.
mlx_gpu	The mlx backend: single-precision propagation on Apple-silicon GPUs (SEP 33).
multistep	The interaction-picture Adams march every CPU backend steps with (SEP 13, SEP 14).
numba_cpu	The CPU backend: fused numba kernels over FFTW plans.
numpy_ref	The NumPy reference backend: the oracle.
populations	Map backend channel reductions onto the mixture's ordered species axis.
protocol	The seam: what a backend is, and what comes back from one.
registry	Selecting a backend by name, and saying why one is not usable.
spatial	Collect spatial host statistics through bounded transverse reconstruction chunks.
