The complexity of node architectures in supercomputers increases as we cross milestones on the way towards Exascale and beyond. Increasing levels of parallelism in multi- and many-core chips and emerging heterogeneity of computational resources coupled with energy and memory constraints force a reevaluation of our approaches towards operating systems and runtime environments.

The International Workshop on Runtime and Operating Systems for Supercomputers, to be held as a half-day event in conjunction with the SC22 conference, provides a forum for researchers to exchange ideas and discuss research questions that are relevant to upcoming supercomputers and cloud environments for high-performance computing. In addition to typical workshop publications, we encourage novel and possibly immature ideas, provided that they are interesting and on-topic. Well argued position papers are also welcome.

Topics of Interest

The topics include, but are not limited to:
  • OS and runtime system scalability on many-node and multi/many-core systems
  • management of heterogeneous and reconfigurable compute resources, including FPGAs, GPUs, etc.
  • distributed/hybrid/partitioned OSes and runtime systems for Supercomputing
  • system noise analysis and prevention
  • runtime and operating systems for resource disaggregation
  • modeling and performance analysis of runtime systems
  • the use of machine learning and AI techniques in the autotuning of system software
  • OS and runtime considerations for large-volume, high-performance I/O
  • memory management and emerging memory technologies
  • OS and runtime aspects of HPC in the cloud, convergence of Supercomputing and cloud environments
  • infrastructure for cloud functions and serverless computing in the context of HPC
  • virtualization in HPC, including virtual machines and application containers
  • the role of the OS and runtime system in minimizing power usage
