Set the database to the given State.
All transitions must begin from the 'STATE_CLOSED' state or be to the 'STATE_CLOSED' state (There are no nested begin/end pairs at this time.)
The database state is automatically set when Region::begin_mode is called for its associated region, so it may not be necessary to call this method directly.
| [in] | state | The new State to which the database should be set. |

If we are using DW then set some pathnames for writing directly to BB instead of PFS(i.e Lustre)
Check whether user wants to use Cray DataWarp. It will be enabled if: the DW_JOB_STRIPED or DW_JOB_PRIVATE environment variable is set by the queuing system during runtime and the IOSS property ENABLE_DATAWARP set to YES.
We currently only want output files to be directed to BB.

Check the topology of all face/element pairs in the model and fill the "TopoContainer faceTopology" variable with the unique pairs. This information is used for the faceblock/facesets and edgeblock/edgesets. If the 'topo_dimension' is 2, then face/element pairs are generated; if 'topo_dimension' is 1, then edge/element pairs are generated.
| void Ioss::DatabaseIO::close_dw | ( | ) | const |
Function which invokes stageout from BB to Disk, prior to completion of final close.
This function gets called inside closeDatabase_nl(), which checks if Cray Datawarp (DW) is in use, if so, we want to call a stageout before actual close of this file.

If we are planning to use BB(aka Burst Buffer) service, we will call simple C API provided by Cray DataWarp module.
Note: We would only like to use BB during write to avoid cache coherency issues during read. dwPath is the DW namespace which gets set during runtime from environment variable DW_JOB_STRIPED. Afterword, using_dw() function is used extensively for filename redirection for all related subsequent functions(e.g: get_filename, get_file_ptr etc) once burst buffer is found and set to be used.
In this wrapper function we check if user intends to use Cray DataWarp(aka DW), which provides ability to use NVMe based flash storage available across all compute nodes accessible via high speed NIC.

The overlay_count specifies the number of restart outputs which will be overlaid on top of the currently written step before advancing to the next step on the restart database.
For example, if restarts are being output every 0.1 seconds and the overlay count is specified as 2, then restart will write time 0.1 to step 1 of the database. It will then write 0.2 and 0.3 also to step 1. It will then increment the database step and write 0.4 to step 2; overlay 0.5 and 0.6 on step 2... At the end of the analysis, assuming it runs to completion, the database would have times 0.3, 0.6, 0.9, ... However, if there were a problem during the analysis, the last step on the database would contain an intermediate step.
The cycle_count specifies the number of restart steps which will be written to the restart database before previously written steps are overwritten.
For example, if the cycle count is 5 and restart is written every 0.1 seconds, the restart system will write data at times 0.1, 0.2, 0.3, 0.4, 0.5 to the database.
It will then overwrite the first step with data from time 0.6, the second with time 0.7. At time 0.8, the database would contain data at times 0.6, 0.7, 0.8, 0.4, 0.5. Note that time will not necessarily be monotonically increasing on a database that specifies the cycle count.
The cycle count and overlay count can both be used at the same time also. The basic formula is:
db_step = (((output_step - 1) / overlay) % cycle) + 1
where "output_step" is the step that this would have been on the database in a normal write (1,2,3,....) and "db_step" is the step number that this will be written to.
If you only want the last step available on the database, use set_cycle_count(1)

bbName is a temporary swizzled name which resides inside Burst Buffer namespace. This is a private trivial mapped name vs original DBFilename (which resides in permanent storage backed by parallel filesystem. dwPath is global BB mountpoint for current job with requested capacity via SLURM #DW directive. usingDataWarp – a boolean, for convenience of use so that we don't have to do getenv() calls to see if BB present.

Typically used for restart output, but can be used for all output... Maximum number of states on the output file. Overwrite the existing steps in a cyclic manner once exceed this count.

The properties member data contains properties that can be used to set database-specific options. Examples include compression, name lengths, integer sizes, floating point sizes. By convention, the property name is all uppercase. Some existing properties recognized by the Exodus DatabaseIO class are:

|---|---|
| COMPRESSION_LEVEL | In the range [0..9]. A value of 0 indicates no compression |
| COMPRESSION_SHUFFLE | (true/false) to enable/disable hdf5's shuffle compression |

Scale the time read/written from/to the file by the specified scaleFactor. If the database times are 0.1, 0.2, 0.3 and the scaleFactor is 20, then the application will think that the times read are 2.0, 4.0, 6.0.
If specified for an output database, then the analysis time is divided by the scaleFactor time prior to output.
