Detailed Description

template<std::size_t Rank>
struct Aleph::CA::Column_Partition< Rank >

Column partitioning along the last axis.

Columns are not contiguous in row-major memory, so this strategy trades cache locality for finer-grained partitioning when axis 0 is small (e.g. a 1D very-tall lattice or a 2D lattice with one row). Provided for completeness; Row_Partition is the default in the engine.

Template Parameters

Rank	lattice dimension.
