Package: libhdf5-serial-dev
Version: all
Severity: wishlist
Tags: newcomer
Dear Debian HDF5 Maintainers,
I realized a long-standing problem with the different package versions
of hdf5 where I would like to propose a redesign of the dependencies for.
Basically, hdf5 compiled with --enable-parallel enables an *additional*
API for parallel reads&writes but at the same time *still provides* the
standard, serial API.
Still, most of the packages in Debian that depend on hdf5 are compiled
against
libhdf5-serial(-dev)
even if they would work perfectly fine when linked against the parallel
version (they would still only use the serial API).
That causes a user/developer that wants to use mpi parallel versions to
force-de-install packages and tools such as
- hdf5view
- hdf5-tools
- h5py (btw: they also have a parallel API)
- ...
Since the parallel API plainly expands the serial version and both
library versions should even be fully ABI compatible, I therefore suggest:
Let us list the packages
- libhdf5-mpi/mpich/openmpi
as "Enhances" the serial versions of the packages.
Do you have any comments on that?
Thank you and all the best,
Axel Huebl
