legate.core.task.PyTask.prepare_call

PyTask.prepare_call(self, *args: Any, **kwargs: Any) → AutoTask

Prepare a task instance for execution.

Parameters:

• *args (Any, optional) – The positional arguments to the task.

• **kwargs (Any, optional) – The keyword arguments to the task.

Returns:

The configured task instance.

Return type:

AutoTask

Raises:

• RuntimeError – If the task has not completed registration before calling this method.

• TypeError – If the type of an argument does not match the expected type of the corresponding argument to the task.

• ValueError – If multiple arguments are given for a single argument. This may occur, for example, when a keyword argument overlaps with a positional argument.

Notes

It is the user’s responsibility to invoke the returned task instance, either through task.execute() or get_legate_runtime().submit(task).

The user is not allowed to add any additional inputs, outputs, scalars or reductions to task after this routine returns.
