Add flag useFixedOrder to the coarsen method of AMGs ParallelIndicesCoarsener. · 4b4c92ca

Lisa Julia Nebel authored 1 year ago and

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.

index of the first vertex is not in the set other vertices of the same
aggregate might be represented there. Therefore we now check all of
them whether they present anf if one is present the coarse index set
will get an according index for the aggregate.

AMG runs in parallel now. · 176a5715

Markus Blatt authored 19 years ago

There was huge bug in the numbering of the aggregates:

Due to the coarsening of the index set the matrix on the coarse level are ordered like this. First come the row corresponding to vertices owned by the process
(0, 1, ..., n) and the the rows owned by other process (n+1, n+2, ..., N).

Unfortunately during the setup of the sparsity pattern of the matrix this fact was neglected :-(

Fixed this now.
