     76    The new Input/Output server XIOS is a major evolution including a versatile xml interface, the dedicated processors for I/O functionality allowing improved scalability, and a large performance improvement on massively parallel platforms. This option is now set as the default one. The previous IOIPSL code and interface are kept as backup options at this stage.
