legate::mapping::Task

class Task

A metadata class for tasks.

Public Functions

LocalTaskID task_id() const

Returns the task id.

Returns:

Task id

std::vector<Store> inputs() const

Returns metadata for the task’s input stores.

Returns:

Vector of store metadata objects

std::vector<Store> outputs() const

Returns metadata for the task’s output stores.

Returns:

Vector of store metadata objects

std::vector<Store> reductions() const

Returns metadata for the task’s reduction stores.

Returns:

Vector of store metadata objects

std::vector<Scalar> scalars() const

Returns the vector of the task’s by-value arguments. Unlike mapping::Store objects that have no access to data in the stores, the returned Scalar objects contain valid arguments to the task.

Returns:

Vector of Scalar objects

Store input(std::uint32_t index) const

Returns metadata for the task’s input store.

Parameters:

index – Index of the input store

Returns:

Store metadata object

Store output(std::uint32_t index) const

Returns metadata for the task’s output store.

Parameters:

index – Index of the output store

Returns:

Store metadata object

Store reduction(std::uint32_t index) const

Returns metadata for the task’s reduction store.

Parameters:

index – Index of the reduction store

Returns:

Store metadata object

Scalar scalar(std::uint32_t index) const

Returns a by-value argument of the task.

Parameters:

index – Index of the scalar

Returns:

Scalar

std::size_t num_inputs() const

Returns the number of task’s inputs.

Returns:

Number of input stores

std::size_t num_outputs() const

Returns the number of task’s outputs.

Returns:

Number of output stores

std::size_t num_reductions() const

Returns the number of task’s reductions.

Returns:

Number of redeuction stores

std::size_t num_scalars() const

Returns the number of Scalars.

Returns:

Number of Scalars

bool is_single_task() const

Indicates whether the task is parallelized.

Returns:

true The task is a single task

Returns:

false The task is one in a set of multiple parallel tasks

const Domain &get_launch_domain() const

Returns the launch domain.

Returns:

Launch domain
