Struct Trace

Fields

high_water: BTreeMap<BufferId, usize>

Peak pages resident (queued + filled-pending) per buffer.

steps: u64

tiles_read: BTreeMap<(TensorId, usize), u64>

Tiles each tensor had read, per section (0 for a program of one workload): what the run actually moved.

held: BTreeMap<BufferId, (i64, i64)>

The least and the greatest integer each buffer’s pages held.

nodes: BTreeMap<StageId, Vec<Option<(i64, i64)>>>

For each stage running an integer Generic body, the least and the greatest value each of its nodes computed — in TensorBody::post_order, both arms of a select at every point, None for a node that never computed one.

stage_held: BTreeMap<StageId, (i64, i64)>

The least and the greatest integer each compute stage kept in its accumulator: a contraction’s and a fold’s partial results, a matmul’s partial sums, the values it wrote.

Trait Implementations

impl Clone for Trace

fn clone(&self) -> Trace

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Trace

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Trace

fn default() -> Trace

Returns the “default value” for a type.
