Cactus offers a hyperslabbing API, which transfers chunks of arrays  
between processors.  If the users' guide is too cryptic, then we

Cactus offers several I/O thorns that can output data in standard  
formats, such as ASCII and HDF5.  However, if you need your own  
special format, then writing the data yourself as you did is often  
the easiest way.
