Pending request, weight supp can be enabled (there are some issues that a mask is essentially a weight with 1 or 0 value). Modifying or extending this thorn is quite a simple matter. The heart of all the reduction -operations is the large iterator macro in local_reductions.h. This iterator supports n-dimensional +operations is the large iterator macro in local\_reductions.h. This iterator supports n-dimensional arrays with offsets and strides. The iterator is used in all local reduction operators in this thorn. To add a reduction operator, or change an existing one, all that needs to be done is to change the actual reduction operation definition which is called from within the iterator to perform the reduction. To use a custom local reduction operator from the new global reduction implementation, some values must be returned to the global reduction implementation, such as the type of MPI reduction operation that -needs to be performed (MPI_SUM, MPI_MIN, MPI_MAX) and if the final result should include a division by the -total number of points used in the reduction. These are set in the parameter table with keys: mpi_operation and perform_division. +needs to be performed (MPI\_SUM, MPI\_MIN, MPI\_MAX) and if the final result should include a division by the +total number of points used in the reduction.
