PackedMatrixLayout

class PackedMatrixLayout(val role: PackedRole, val rows: Int, val columns: Int, val group: Int, val depthStride: Int = group, val groupStride: Int = checkedStorageSize( (if (role == PackedRole.Left) columns else rows).toLong() * depthStride, ), val layoutId: Int = GROUPED_FP64, val version: Int = 1, val alignmentBytes: Int = Double.SIZE_BYTES, val requiredSvlBytes: Int = 0)(source)

Version one grouped FP64 format. Grouping is independent of compute microtiles and triangular solve order. depthStride separates depth steps, groupStride separates groups, and group lanes are reserved per step. Every padding entry in the storageSize extent is positive zero when produced by ScalarLayoutKernels. Heap arrays guarantee natural Double alignment only; alignmentBytes cannot promise a stronger alignment. A nonzero requiredSvlBytes restricts exact consumers to that streaming length; zero is length independent.

Constructors

Types

object Companion

Factories and format identifiers.

Properties

alignmentBytes

val alignmentBytes: Int(source)

Guaranteed storage alignment in bytes.

columns

val columns: Int(source)

Logical column count.

depthStride

val depthStride: Int(source)

Physical distance between depth steps.

group

val group: Int(source)

Number of contiguous lanes in each depth step.

groupStride

val groupStride: Int(source)

Physical distance between groups.

layoutId

val layoutId: Int(source)

Stable physical format identifier.

requiredSvlBytes

val requiredSvlBytes: Int(source)

Required streaming vector length, or zero when length independent.

role

val role: PackedRole(source)

Left or right grouped product role.

rows

val rows: Int(source)

Logical row count.

storageSize

val storageSize: Int(source)

Number of entries in the complete physical extent, including padding.

version

val version: Int(source)

Physical format version.

Functions

requireCompatible

fun requireCompatible(layoutId: Int, version: Int, svlBytes: Int = 0)(source)

Rejects an incompatible consumer before it can mutate output. Zero svlBytes means unknown.
