PyPnetCDF: A high level framework for parallel access to netCDF files

A Python tool for manipulating netCDF files in a parallel infrastructure is proposed. The parallel interface, PyPnetCDF, manages netCDF properties in a similar way to the serial version from ScientificPython, but hiding parallelism to the user. Implementations details and capabilities of the developed interfaces are given. Numerical experiments that show the friendly use of the interfaces and their behaviour compared with the native routines, are presented.
