Struct DecodeChipDesign 

pub struct DecodeChipDesign {
    pub node: Node,
    pub die_mm2: f64,
    pub sram_fraction: f64,
    pub tile_bytes: f64,
    pub network: OnChipNetwork,
    pub hop_cycles: f64,
    pub link_modules: u32,
}

A decode chip design point: the choices, over a node’s facts.

Fields

node: Node

die_mm2: f64

sram_fraction: f64

The share of the die that is SRAM array.

tile_bytes: f64

SRAM per tile, bytes.

network: OnChipNetwork

hop_cycles: f64

Cycles one on-chip network hop takes: one is a registered link.

link_modules: u32

UCIe modules each chip’s collectives stripe across.

Implementations

impl DecodeChipDesign

pub fn at(node: Node, die_mm2: f64) -> DecodeChipDesign

A dataflow die at node: half its area SRAM, 256 KiB tiles on a registered reduction tree, sixteen UCIe modules to its neighbours.

pub fn link(&self, hop_latency_s: f64) -> Link

The design’s chip-to-chip link at hop_latency_s.

pub fn sram_bytes(&self) -> f64

pub fn tiles(&self) -> f64

pub fn stage_hops(&self) -> f64

Hops one dependent stage makes on chip: its vector out to every tile and its partial sums back.

pub fn stage_latency_s(&self) -> f64

Seconds one dependent stage spends on the network.

pub fn chip_with(&self, stage_s: f64, link: Link) -> Chip

The chip, with a chip-to-chip link and a per-stage overhead of stage_s (the design’s own, or a budget under test).

Trait Implementations

impl Clone for DecodeChipDesign

fn clone(&self) -> DecodeChipDesign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeChipDesign

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

Formats the value using the given formatter.

impl PartialEq for DecodeChipDesign

fn eq(&self, other: &DecodeChipDesign) -> 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 DecodeChipDesign

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
