solprop.backends#

Execution backends behind one seam.

The NumPy reference and native backends (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, and the thread budget every backend’s pools are held within.

Modules

`adams_core`	The Adams march's controller as functions of its policy and its state (SEP 39).
`batch`	Establish fixed-schedule lockstep with independent backend workspaces.
`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`	Byte counts and sizes the backends share for their memory ledgers.
`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).
`multistep_general`	The general Adams path: the comparison variants SEP 13 did not select.
`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.
`rk_core`	The Runge-Kutta march's controller as functions of its policy and state (SEP 45).
`spatial`	Collect spatial host statistics through bounded transverse reconstruction chunks.
