ESiWACE2 plans to create descriptive course material covering the co-designed software stack of WP4 as a standardised and efficient platform for I/O and on how the analysis stack (Cylc, XIOS, ESDM, NetCDF, HDF5) integrates with the underlying storage APIs and file systems (e.g., Mero/Clovis, Lustre), efficient creation of I/O dominated workflows, performance and efficiency considerations when dealing with file systems, NVM, tape or object storage, and cost-considerations in storage architectures.


  • Software stack as a standardised and efficient platform for Data Input/Output (I/O)
  • Storage application programming interfaces (APIs) and file systems
  • Efficient creation of I/O workflows
  • Performance and efficiency of file systems, non-volatile memory (NVM), tape or object storage

The material covers roughly 8 hour course work in the form of presentations and a summarising paper covering the individual aspects, with webinars presenting the created OER material and blog entries describing issues. We plan to harness existing community approaches like the Virtual Institute of I/O (VI4IO, for promoting this training.

End-users of the weather and climate data community, but the course is generally useful for any data-intensive science.

This training is planned as an 8-hour course via webinars and/or blog entries, delivered during the ESiWACE2 Summer Schools:
