File pnetcdf.hxx¶

Parallel NetCDF data format interface.

Records: In netCDF, the time dimension for each dimension must be the same. Hence when a record is appended to a variable, the size of all variables is increased. To work out which record to write to, a map of variable names to record number is kept.
