Detailed Description

Shared vocabulary and conventions of the solver families.

Knob types shared by the configuration of every solver family: the elimination schedule of a factorization and the memory layout of a dense matrix. Each family configuration carries its own members of these types.

The families also share one calling convention. Every operand is a raw pointer pre-offset by the caller plus one runtime element stride, which covers the AoS, SoA and AoSoA batch layouts alike. Offsets are computed in 32-bit arithmetic: the flat element index of an object (N*N for a matrix) must stay below 2^31 and every element offset, index times stride, below 2^32. Residency template booleans, where a solver offers them, describe what the passed buffers are and carry no default. Factorizing entry points come in counting and diagnostics-free overloads, the latter compiling the diagnostics out entirely.

Macro Definition Documentation

◆ TDLS_LAYOUT_INDEX

#define TDLS_LAYOUT_INDEX	(	r,
		c,
		dim )

Value:

(Config.layout == tdls::MatrixLayout::RowMajor ? unsigned((r) * (dim) + (c)) \

: unsigned((c) * (dim) + (r)))

Flat index of matrix element (r, c) under the configured layout: r * dim + c row-major, c * dim + r column-major.

Expands inside solver member functions, where a constexpr Config value carrying a layout member is in scope.

Enumeration Type Documentation

◆ MatrixLayout

enum class tdls::MatrixLayout

strong

Memory layout of a dense matrix.

Enumerator
RowMajor	Element (r, c) at flat index r * N + c, the TFEL convention.
ColMajor	Element (r, c) at flat index c * N + r.

◆ Schedule

enum class tdls::Schedule
