legate.core.operation.Copy.add_reduction

Copy.add_reduction(store: Store, redop: int) → None

Adds a store as a reduction target of the copy. To avoid ambiguity in matching sources and targets, one copy cannot have both normal targets and reduction targets.

Parameters:

• store (Store) – Reduction target store

• redop (int) – Reduction operator ID

Raises:

• RuntimeError – If the copy already has a normal target

• ValueError – If the store is scalar or unbound
