Detailed Description

Enumeration Type Documentation

EDistribution

enum Amesos2::EDistribution

An enum of this type is expected by the Matrix adapters' getCrs and getCcs functions to describe the layout of the representation on the calling processors.

Enumerator
DISTRIBUTED	no processor has a view of the entire matrix, only local pieces
DISTRIBUTED_NO_OVERLAP	no row or column may be present on more than one processor
GLOBALLY_REPLICATED	each processor has a view of the entire matrix
ROOTED	only rank=0 has a full view, all others have nothing.
CONTIGUOUS_AND_ROOTED	the global GIDs of the map are not contiguous

EStorage_Ordering

enum Amesos2::EStorage_Ordering

This enum also used by the matrix adapters to indicate whether the indices of the representation must be in sorted order or can have an arbitrary order.

Enumerator
SORTED_INDICES	row/col indices need to appear in sorted order
ARBITRARY	index order can be arbitrary
