Detailed Description

SoA Lexicographic Enumerator.

Enumerates the degrees of freedom assuming that they are

  • organised as structure of arrays, i.e., if you store quantities (a,b,c) per degree of freedom, then the array first holds the a values, then all the b values, then all the c values.
  • organised lexicographically, i.e., we first enumerate all the degrees of freedom along the x-axis, then along the y-axis, then along the z-axis.
  • organised from left to right, bottom-up and front to back.
  • organised one cell after another, i.e., we first enumerate all the a values of the first cell, followed by all the a unknowns of the second cell, and so forth. After the a values of the last cell, we continue with the b values in the examples with (a,b,c) per degree of freedom.

This native SoA enumerator uses SoA within the cells plus over cells: It first enumerates all Q[0] data from cell one, then all Q[0] from cell two, then all Q[0] from cell three, and so forth. After that, it continues with Q[1]. This means: The enumerator interleaves the individual cells.

◆ operator()()

GPUCallableInlineMethod int exahype2::enumerator::SoALexicographicEnumerator::operator() ( int cellIndex,
const tarch::la::Vector< Dimensions, int > & volumeIndex,
int unknown ) const

Access an index.

The index always refers to the interior of the cells. So you can use negative indices if you want.
