Description

TIL: https://github.com/BlueBrain/HighFive

A third-party, C++(11) API for HDF5, even supporting parallel I/O :)

(Note: we stay with the official C-API for our HDF5 backend now. But if we want to try this C++ library, we would write a second HighFive backend for it.)

We currently implement serial & parallel HDF5 via the official HDF5 C-API.

Additionally, we could implement another HDF5 backend via HighFive's C++ API.
