Prerequisites

NetCDF/HDF5 (on JURECA)

How to find out what modules to load for NetCDF/HDF5:

If ncdump returns netCDF-4, or netCDF-4 classic model, then congratulations, you already have an HDF file, as netCDF-4 is the netCDF data model implemented using HDF5 as the storage layer. These files can be ready by the HDF library version 1.8 or later, and from what I can tell, pytables. If ncdump returns classic or 64-bit offset, then you are using netCDF-3 and will need to convert to netCDF-4 (and thus HDF). The good news is that if you have netCDF installed, you can do the conversion pretty easily:

Graphical hdf5 viewer: HDFView is a very handy tool to investigate hdf5 files. To open HDFView on JURECA, either click on the HDFView icon on the desktop. Or launch HDFView by

Python on JURECA

To use Python on JURECA, you have to load some modules first, e.g.
