NetCDF
NetCDF is a binary scientific data file. A classic file starts with the
three ASCII bytes CDF and a version byte (0x01 or 0x02). A NetCDF-4
file is an HDF5 file and starts with the HDF5 signature. The format notes
are in the
NetCDF format specifications.
There is no official OSI-licensed parse corpus in this suite. The cases
under compliance/data/netcdf/ are original. They check those signatures
and a truncated header. They are not a full NetCDF conformance suite.
No adapter is required to score them. An empty cell stays empty.
Versions
| Version | Parser-visible difference |
|---|---|
| classic | Magic CDF and version 0x01. |
| 64-bit offset | Magic CDF and version 0x02. |
| NetCDF-4 | The HDF5 signature. The file is HDF5 with NetCDF-4 conventions. |
What the cases cover
- Classic and 64-bit-offset signatures
- A NetCDF-4 / HDF5 signature
- Rejects: a two-byte truncated classic header
Catalog: compliance/data/netcdf/. Inputs are hex.
Fortran serializer
netcdf-fortran times the official Fortran API on the array data set
(grid and grid_window) as a real NetCDF-4 file.
NF90_DISKLESS discards the file on close, so that flag is not a bytes
row. The benchmark publishes the file timing through config/file-only.txt.
It does not decode this corpus.
