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).
driver	The step loop every backend runs, with the kernels left abstract.
events	The records an execution session hands its service loop (SEP 47 section 5.3).
exponential	The phi functions and exponential Adams weights, in NumPy (SEP 16 sections 4.2-4.3).
export	Destination-based export of a session's field (SEP 47 section 5.4).
host	The NumPy reference's own host execution machinery (SEP 47 phase 2).
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.
multistep	The interaction-picture Adams march every CPU backend steps with (SEP 13, SEP 14).
node_chunk	How many nodes a response pass holds at once: the backend's node-chunk plan.
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).
session	The execution-session contract between solprop and a backend (SEP 47 section 5).
session_core	The building blocks the Python execution sessions share (SEP 47 sections 5 and 6.7).
sessions	The run layer's one door to a backend's sessions (SEP 47 phases 2 to 5).
spatial	Collect spatial host statistics through bounded transverse reconstruction chunks.
