Add BCRSMatrix::setIndicesNoSort() and speedup MatrixIndexSet::exportIdx()

See merge request !550

Before this patch `BCRSMatrix::addindex()` was used on individual
column indices. This is slow because each insertion does a binary
search although the inserted indices are already sorted. Bulk-inserting
whole rows with `setIndices()` improves on this significantly but still
does a non-necessary sort. The latter is avoided by the new
`BCRSMatrix::setIndicesNoSort()` method.

This is similar to `setIndices()` but does not sort indices
after insertion which allows to avoid an additional sort
on an already sorted range. The latter e.g. is the case when
using sorted containers as it is done in `MatrixIndexSet`.

Fix Doxygen warnings

Add line breaks.
Remove indentation as Doxygen treats it as <pre>.

Add flag useFixedOrder to the coarsen method of AMGs ParallelIndicesCoarsener.

See merge request !553

This tests makes sure the matrices in the hierarchy get created in a deterministic way when the flag 'useFixedOrder' of the coarseningCriterion is set to true.

Lisa Julia Nebel authored 1 year ago and Lisa Julia Nebel committed 1 year ago

If set to true, the indices for the coarser grid will be created in a fixed order, making parallel runs reproducible but the runtime is possibly not ideal.
If set to false (which is the default), the order depends on the order of messages recieved from the processes responsible for the respective parts of the finer grid.
Then the indices on the coarser grid may differ from run to run.
