Package: libnetcdf19
Version: 1:4.9.2-1
Severity: normal

netcdf is currently built against the serial variant of hdf5
(libhdf5_serial.so.103).

But hdf5 provides a parallel build
e.g. libhdf5_openmpi.so.103.3.1
via libhdf5-mpi-dev

netcdf can be configured to support parallel io 
https://salsa.debian.org/debian-gis-team/netcdf/-/blob/master/INSTALL.md#building-with-parallel-io-support-build_parallel

In principle parallel io could allow for much faster reading and
writing of large data files.

Should netcdf be configured to start enabling parallel io?

Or would it be useful to provide both serial and parallel variants
like hdf5 does?
