Towards Resilient EU HPC Systems: A Blueprint (April 2020)
This document aims to spearhead a Europe-wide discussion on HPC system resilience and to help the European HPC community define best practices for resilience. We analyse a wide range of state-of-the-art resilience mechanisms and recommend the most effective approaches to employ in large-scale HPC systems. Our guidelines will be useful in the allocation of available resources, as well as guiding researchers and research funding towards the enhancement of resilience approaches with the highest priority and utility. Although our work is focussed on the needs of next generation HPC systems in Europe, the principles and evaluations are applicable globally.
This document is the first output of the ongoing European HPC resilience initiative and it covers individual nodes in HPC systems, encompassing CPU, memory, intra-node interconnect and emerging FPGA-based hardware accelerators. With community support and feedback on this initial document, we will update the analysis and expand the scope to include other types of accelerators, as well as networks and storage.
