===== SIOX ======

Scalable I/O For Extreme Performance

=====The HPC I/O Challenge=====
During the last decades, increases in processor performance have exceeded those in I/O capacity by a full order of magnitude.

Efforts to bridge this growing gap gave rise to ever more complex I/O architectures, comprising many layers of heterogeneous hard- and software that make performance analysis and localisation of bottlenecks a daunting task at best.

=====The SIOX Approach=====
The BMBF-funded project Scalable I/O for Extreme Performance (SIOX) aims to create a system that will aid in and finally automate I/O analysis and optimisation.

To this end, access and performance data will be
    * recorded
      * on all levels
      * in a level-independent format,
    * causally correlated,
    * structured and archived.
SIOX will use the data collected to
    * predict possible performance,
    * evaluate actual performance,
    * locate and analyse bottlenecks and
    * suggest optimized parameters.
 
The system built is to be deployed on a multitude of parallel file systems running under various operating systems, spanning all major hardware architectures.

Project results will be tested and used with a range of real world climate modelling applications from the DKRZ project portfolio.

=====Interfaces=====
{{:research:projects:siox-apis.png?200 |}}
All interaction with SIOX is built on the low-level interface ''siox-ll''. Later, the SIOX project will provide more comfortable and well-adapted high-level interfaces for each of the types of logical nodes, such as siox-cache, siox-network or siox-blockstorage. Furthermore, wrappers may be used to easily adapt software already instrumented for other tools to SIOX. Both high-level APIs and wrappers will build upon ''siox-ll'' to perform their tasks.
