Enum PackerAccumulate 

pub enum PackerAccumulate {
    No,
    InLocalMemory,
    IntoTheOutput,
}

Whether a matrix engine’s packer can ADD into a local-memory page instead of overwriting it.

Variants

No

The packer only overwrites.

InLocalMemory

The packer adds into a local-memory page, so a blocked reduction’s partial sum stays in local memory between K blocks instead of round-tripping through the register file each block.

IntoTheOutput

…and the page it adds into can be the OUTPUT’s: the intermediate and the output share one local region (two indices of one tt-metal CircularBufferConfig, Tensix pack_reconfig_l1_acc), so a reduction whose partial already is the result finishes in the page the writer stores, with no reload.

Trait Implementations

impl Clone for PackerAccumulate

fn clone(&self) -> PackerAccumulate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackerAccumulate

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

Formats the value using the given formatter.

impl Hash for PackerAccumulate

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PackerAccumulate

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
