IS-ENES2_MS9.5_New CDI release with I/O developments from IS-ENES1 and ICOMEX

Serial I/O is likely the major performance hurdle to efficient operation of Earth System Models on modern high performance computing systems. The CDI package jointly developed by MPG and DKRZ provides generic solution for asynchronous and parallel writing of model output data to disk via dedicated I/O servers not involved into the computational part of model integration. CDI uses the external YAXT library to accomplish all steps required for data rearranging between compute tasks and I/O servers. Information on how to download the CDI and YAXT packages and to get support is provided in this document.
