¶region<3> compute_consumed_region(
    buffer_id bid,
    const box<3>& execution_range) const

Description

Computes the union of all consumed regions (across multiple accesses) for a given execution range.

Declared at: include/task.h:59

Parameters

buffer_id bid

const box<3>& execution_range

---

¶region<3> compute_produced_region(
    buffer_id bid,
    const box<3>& execution_range) const

Description

Computes the union of all produced regions (across multiple accesses) for a given execution range.

Declared at: include/task.h:62

Parameters

buffer_id bid

const box<3>& execution_range

---

¶box_vector<3> compute_required_contiguous_boxes(
    buffer_id bid,
    const box<3>& execution_range) const

Description

Returns a set of bounding boxes, one for each accessed region, that must be allocated contiguously.

Declared at: include/task.h:65

Parameters

buffer_id bid

const box<3>& execution_range

---

¶const std::unordered_set<buffer_id>&
get_accessed_buffers() const&

¶region<3> get_task_consumed_region(
    buffer_id bid) const

Description

Returns the union of all consumer accesses made across the entire task (conceptually, the union of the set of regions obtained by calling get_consumed_region for each chunk).

Declared at: include/task.h:46

Parameters

buffer_id bid

---

¶region<3> get_task_produced_region(
    buffer_id bid) const

Description

Returns the union of all producer accesses made across the entire task (conceptually, the union of the set of regions obtained by calling get_produced_region for each chunk).

Declared at: include/task.h:53

Parameters

buffer_id bid
