Struct NodeStats 

pub struct NodeStats {
    pub execution_count: u64,
    pub total_time: Duration,
    pub min_time: Duration,
    pub max_time: Duration,
    pub memory_allocated: u64,
    pub peak_memory: u64,
    pub cache_misses: Option<u64>,
    pub flops: Option<u64>,
}

Runtime execution statistics for a single node.

Fields

execution_count: u64

Number of times executed

total_time: Duration

Total time spent executing this node

min_time: Duration

Minimum execution time

max_time: Duration

Maximum execution time

memory_allocated: u64

Total memory allocated (bytes)

peak_memory: u64

Peak memory used (bytes)

cache_misses: Option<u64>

Cache misses (if available)

flops: Option<u64>

FLOPs executed

Implementations

impl NodeStats

pub fn new() -> Self

pub fn record_execution(&mut self, duration: Duration, memory: u64)

Record an execution

pub fn avg_time(&self) -> Duration

Get average execution time

pub fn time_variance(&self) -> Duration

Get time variance (max - min)

pub fn is_hot(&self, threshold: u64) -> bool

Check if this is a hot node (frequently executed)

pub fn performance_score(&self) -> f64

Get performance score (higher is worse - indicates bottleneck)
