This commit adds support for loading a three-column NLDD
partitioning scheme of the form
MPI_Rank Cartesian_Index NLDD_Domain_ID
from a text file. In an MPI run it is assumed that the first column
holds integers in the range 0..MPI_Size()-1, and typically that each
such integer is listed at least once. In a sequential run, the MPI
rank column is ignored.
With this scheme we can load the same partition files that we write,
for increased repeatability and determinism, and we can also
experiment with externally generated NLDD partitions.
This commit switches the current implementation of
'partitionCellsZoltan()', i.e., 'partitionCells("zoltan", ...)' into
using the MPI-aware ParallelNLDDPartitioningZoltan utility. In
doing so we make 'partitionCellsZoltan()' private since its
availability is not guaranteed. We also slightly reorder the
parameters and switch from passing a "Grid" into passing a
"GridView" as an argument to partitionCells(), and specialise this
function for the known grid views in OPM Flow.
We extract the Zoltan-related parameters out to an Entity-dependent
helper structure and move the complexity of forming this type to a
new helper function, BlackoilModelEbosNldd::partitionCells().
Invokes Zoltan library and requires MPI. Client code constructs an
abstract connectivity graph by defining connections/edges through
the 'registerConnection()' member function. May also impose a
restriction that certain cells/vertices be placed in the same
domain/block in the resulting partition. Client code must supply a
callback function that defines globally unique cell/vertex/object
IDs, across all MPI ranks, for each vertex in the connectivity
graph.
Member function 'partitionElement()' forms the resulting partition
vector, the size of which is the total number of objects visible to
the local rank-typically the number of cells owned by the rank, and
the number of overlap cells--i.e., the size of the local grid view.
This should replace OPM_DEFLOG_THROW in places where the problem
category is more appropriate than the error category.
In this commit, uses of OPM_DEFLOG_THROW have been replaced whenever
the exception class used was NumericalProblem.
This commit switches the region set tag matching algorithm to using
unique prefixes. This enables the simulator to recognise that the
region set name
FIPUNI
should match up with the user defined region set 'FIPUNIT'. In the
current master sources, the above summary vector would produce a
diagnostic message saying that the region set 'FIPUNI' (without the
final 'T') does not exist.
To this end, we instruct the ParallelEclipseState to always pass the
six character substring beginning with 'FIP' for FIP-like region
arrays and defer to the rank-0 EclipseState/FieldProps mechanism to
match this prefix with its canonical region set.
Step one for moving Damaris calls out of EclWriter class and into its own DamarisWriter class;
EclProblem now calls both writeOutput methods and passes in the data::Solution object;
Add fix for first writeOutput() call not having PRESSURE data available;
data::Solution is now passed by rvalue ref into eclWriter::writeOutput();
guard added to prevent inclusion of damariswriter.hh
We emit a warning if the model uses connection flag 'ALL', but
continue the run. This behaviour is still being debated and we
may decide to halt the run in this situation.
We now give a different (more explanatory) error if the input grid has
no active cells at all. Often this points to a user error and having a
more precise error message might help here.
