ENH: eliminate unnecessary duplicate communicator - in globalMeshData previously had a comm_dup hack to avoid clashes with deltaCoeffs calculations. However, this was largely due to a manual implementation of reduce() that used point-to-point communication. This has since been updated to use an MPI_Allreduce and now an MPI_Allgather, neither of which need this hack. |
