XIOS, or XML-IO-Server, is a library dedicated to I/O management in climate codes targeted for large core simulation (> 10 000) on climate coupled models.
XIOS manages the output of diagnostics and other data produced by climate component codes into files and offers temporal and spatial post-processing operations on this data.
XIOS aims at simplifying the I/O management by minimizing the number of subroutines to be called and by supporting a maximum of on-line processing of the data.
