Turn mapping events off on coarse levels

  • We basically will go from here: 
    peano::MappingSpecification
exahype::mappings::XYZ::enterCellSpecification(int level) const {
  return peano::MappingSpecification(
    peano::MappingSpecification::WholeTree,
    peano::MappingSpecification::RunConcurrentlyOnFineGrid,true);
}
    To here: 
    peano::MappingSpecification
exahype::mappings::XYZ::enterCellSpecification(int level) const {
  if (level < exahype::solvers::getCoarsestMeshLevelOfAllSolvers()) {
   return peano::MappingSpecification(
    peano::MappingSpecification::Nop,
    peano::MappingSpecification::RunConcurrentlyOnFineGrid,true);
  }

  return peano::MappingSpecification(
    peano::MappingSpecification::WholeTree,
    peano::MappingSpecification::RunConcurrentlyOnFineGrid,true);
}
  • Second, we should set the alterState bool only to true in mappings where this is necessary, i.e., where we perform reductions or use temporary variables.
