The third DEEP-ER training was co-organised with the Mont-Blanc project at Barcelona Supercomputing Centre and focused on HPC strategies for resiliency and fault tolerance.


Next to a series of introductory talks, the focus clearly was on hands-on workshop sessions with the HPC application developers in both projects.


Our application teams and software experts benefited tremendously from this collaboration activity and made the most of the short time available.

  • The application by partner Inria on ‘Human exposure to electromagnetic fields’ has progressed already quite far in integrating SIONlib and SCR (scalable checkpoint-restart). They focused on OmpSs and benefited from the onsite support by partner BSC.
  • KU Leuven managed to successfully integrate SCR into the mock-up of their space weather code and worked with the experts on SIONlib to further extend the I/O functionalities.
  • For the oil exploration code (FWI = full waveform inversion) from BSC discussions on how to tackle current I/O challenges was extremely useful.

Apart from that, Mont-Blanc and DEEP-ER experts talked about possibilities for how to integrate certain technologies used in one project by the other project and exchanged some first promising ideas.


The training material is availalbe here:
