HDF5 - hierarchical data format

Documentation

HDF5 is a data model, library, and file format for storing and managing data. It can represent very complex data objects and a wide variety of metadata. For a documentation visit the HDF group support portal

The libraries are threadsafe and can be used in omp-parallel codes. To see configure-details on the installed libraries, load a hdf5-module and issue cat $HDF5DIR/libhdf5.settings!

Modules and Prerequisites

  • module avail hdf5 shows all available hdf5 versions
  • module show <modulename> shows environment variables set when loading the module
  • module help <modulename> shows some details on compilers and MPI

Loading a module adds the path to some hdf5-binaries to $PATH. For convenience, some other environmental variables are extended or defined, which satisfies the needs of several software packages for linking the hdf5-libraries:

PATH, LD_RUN_PATH 

C_INCLUDE_PATH, CPLUS_INCLUDE_PATH,

HDF5DIR, HDF5INCLUDE, HDF5LIB

HDF5_HOME, HDF5_ROOT

The module files do not require any prerequisites. All dynamically linked libraries are found, since RPATH is defined in libraries and binaries. For an example, consider

  • readelf -a $HDF5DIR/libhdf5_hl.so | grep RPATH

Linking the hdf5-libraries in user programs

Loading a hdf5-module does not link the libraries automatically, when compiling some other software. hdf5 does not deliver any standard way to detect the path to the libraries like pkg-config. So you have to configure Makefiles or install-scripts "by hand". The environment variables exported by the modules should allow short and flexible notation.

hdf5-modules do not have any effect during the runtime of your binaries. If the hdf5-libraries are linked dynamically, it is recommended to set RPATH in the binary. Otherwise the hdf5-libraries (and others) will not be found, during runtime. This can be done with the compiler option -Wl,-rpath=$LD_RUN_PATH, which passes the rpath to the linker.

hdf5 compiler wrapper

The compiler wrapper h5cc, h5fc (parallel h5pcc and h5pfc) can be used to build programs linking the hdf5-libraries. These wrappers set rpath for all libraries to be linked dynamically for hdf5.
