Struct Roofline 

pub struct Roofline {
    pub bounds: Vec<Bound>,
    pub ops: f64,
    pub dram_bytes: f64,
}

A program’s roofline on a target: one lower bound per resource the target has a roof for, the largest of which binds. A resource with no roof has no bound; nothing is priced at a guessed rate.

Fields

bounds: Vec<Bound>

ops: f64

The matrix operations the program performs — its arithmetic, 2 · M · N · K for a GEMM, however many fidelity passes the engine makes over it.

dram_bytes: f64

The bytes it moves to and from the memory every site shares.

Implementations

impl Roofline

pub fn binding(&self) -> Option<&Bound>

The bound that binds: the resource the program waits on longest.

pub fn cycles(&self) -> f64

No schedule of this work finishes in fewer cycles.

pub fn intensity(&self) -> Option<f64>

Operations per DRAM byte, the arithmetic intensity: where the program sits on the roofline’s horizontal axis.

Trait Implementations

impl Clone for Roofline

fn clone(&self) -> Roofline

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Roofline

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

Formats the value using the given formatter.

impl PartialEq for Roofline

fn eq(&self, other: &Roofline) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Roofline

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
