This commit adds a new (hidden) debugging option, DebugEmitCellPartition (--debug-emit-cell-partition) which, when set, will cause each rank to write a three-column text file of the form MPI_Rank Cartesian_Index NLDD_Domain_ID into the directory partition/CaseName of the run's output directory. That file will be named according to the process' MPI rank, so the first column will be the same as the file name. The option is primarily intended for debugging the NLDD partitioning scheme, so is mostly reserved for runs with low MPI sizes (e.g., less than 20). While here, also make the MPIPartitionFromFile helper class aware of this format so that we can use concatenated output files as an input to the MPI partitioning algorithm for repeatability. |
