val initialize : Backend_intf.config -> Base.unit

Initializes a backend before first use. Typically does nothing if the backend is already initialized, but some backends can do some safe cleanups.

val is_initialized : Base.unit -> Base.bool

Returns false if there was no previous initialize call. If it returns false, one must call initialize before using the backend.

The ctx_arrays already contain the arrays of the resulting context. runner_label will be get_name stream of the stream holding the resulting ctx_arrays.
