A wrapper class for a block Jacobi preconditioner for Trilinos matrices. As opposed to PreconditionSOR where each row is treated separately, this scheme collects block of a given size and inverts a full matrix for all these rows simultaneously. Trilinos allows to select several strategies for selecting which rows form a block, including "linear" (i.e., divide the local range of the matrix in slices of the block size), "greedy" or "metis". Note that the term block Jacobi does not relate to possible blocks in the MPI setting, but small blocks of dense matrices extracted from the sparse matrix local to each processor.
The AdditionalData data structure allows to set preconditioner options.
