Abstract: Examples relate to an apparatus, a device, a method, and a computer program for monitoring one or more software containers being hosted by a computer system, to an apparatus, a device, a method, and a computer program for generating information on an expected behavior of software components of software containers, and to corresponding computer systems. The apparatus for monitoring the one or more software containers comprises processing circuitry configured to determine information on an expected behavior of the one or more software containers based on respective software components being executed or used within the one or more software containers. The processing circuitry is configured to determine information on a monitored behavior of the one or more software containers. The processing circuitry is configured to determine a fault condition of a software container based on a deviation between the expected behavior of the software container and the monitored behavior of the software container.

Abstract: Methods and apparatus for optimizing fault tolerance on HPC (high-performance computing) systems including systems employing exascale architectures. The method and apparatus implement one or more management/service nodes in a management/service node layer and a plurality of sub-management nodes in a sub-management node layer. The sub-management nodes implement redundant cross-connected software components in different sub-layers to provide redundant channels. The redundant software components in a lowest sub-layer are connected to switches in racks containing multiple service nodes. The sub-management nodes are configured to employ the multiple redundant channels to collect telemetry data and other data from the service nodes such that the system continues to collect the data in the event of a failure in a software component or hardware failure.
