SUMMARY:The LUMI Case: Towards High Performance Confidential Computing wit
 h Containers
DESCRIPTION:Minisymposium\n\nMartin Matthiesen (CSC - IT Center for Scienc
 e) and Timothy Dykes (HPE)\n\nTim Dykes and Martin Matthiesen will discuss
  the topic of confidential high performance computing from both the platfo
 rm vendor and operational perspectives in the context of Europe's HPC Flag
 ship LUMI. The talk will initially outline the requirement for secure work
 loads in HPC, highlighting the challenges presented by system architecture
 , system software, applications, typical usage patterns, threat models, an
 d common misconceptions surrounding confidentiality and data processing. W
 e will briefly cover examples of existing approaches to support confidenti
 al workloads on HPC systems, and then present an overview of a joint effor
 t to develop an end-to-end container-based technology prototype for remote
  workload execution on Cray EX supercomputers. We consider protection from
  in-storage, in-flight, and in-execution access by third parties through c
 ontainer encryption, secure sub-networks, and a fully attested hardware an
 d software stack, without requiring any application modification. We will 
 discuss our experiences building this technology from both the platform ve
 ndor and data-center operator perspectives, and contrast with other approa
 ches also in use. We will summarise highlighting future work and outstandi
 ng challenges to be solved.\n\nDomain: Computational Methods and Applied M
 athematics\n\nSession Chairs: Timothy Dykes (HPE) and Tiziano Müller (HPE)
