Expand description

Full cost summary for an EinsumGraph.

Fields§

§node_costs: Vec<NodeCostEstimate>

Per-node cost estimates, in node-index order.

§total_flops: FlopEstimate

Sum of FLOPs across all nodes.

§total_memory: MemoryCostEstimate

Sum of memory estimates across all nodes.

§peak_memory_bytes: u64

Maximum peak_bytes across all nodes.

§bottleneck_nodes: Vec<usize>

Node indices flagged as bottlenecks.

§num_nodes: usize

Total number of nodes estimated.

§estimated_time_ns: Option<u64>

Estimated wall-clock time in nanoseconds; None if throughput unknown.
