ViTables is a graphical browser for HDF5 and PyTables databases. It can open arbitrarily large files and browse their data and metadata in a variety of ways. Its capabilities include easy navigation through the data hierarchy, displaying of real data and its associated metadata, and simple yet powerful browsing of multidimensional data.
The ExaScale IO (ESIO) library provides simple, high throughput input and output of structured data sets using parallel HDF5. It is designed to support reading and writing of turbulence simulation restart files, but it may be useful in other contexts. The library is written in C99 and may be used by C89 or C++ applications. A Fortran API built atop the F2003 standard ISO_C_BINDING is also available.
