legate.core.task.PyTask

class legate.core.task.PyTask(func: UserFunction, *, variants: Sequence[VariantCode], constraints: Sequence[ConstraintProxy] | None = None, options: TaskConfig | VariantOptions | None = None, invoker: object = None, library: object = None, bool register: bool = True)

A Legate task constructed from a Python callable.

__init__()

Construct a PyTask.

Parameters:

• func – The base user function to invoke in the task.

• variants – The list of variants for which func is applicable.

• constraints – The list of constraints which are to be applied to the arguments of func, if any. Defaults to no constraints.

• invoker – The invoker used to store the signature and marshall arguments to and manage invoking the user variants. Defaults to constructing the invoker from func.

• library – The library context under which to register the new task. Defaults to the core context.

• register – Whether to immediately register the task with library. If False, the user must manually register the task (via PyTask.complete_registration()) before use.
