    • For HPE Cray EX systems with NVIDIA CPUs and GPUs, please use the August 2024 (CSM 1.5.x) HPE HPC continuous software stack.
    • These software stacks were validated with NVIDIA HPC SDK 24.3.
    • The March 2025 HPE HPC continuous and extended software stack releases will be validated with NVIDIA HPC SDK 24.11.
    • The March 2025 (CSM 1.6.1) software stacks will support all HPE Cray EX systems.

  • After updating Paradise BMC firmware, the hmcollector-poll service will lose event subscriptions and must be restarted

  • cfs-api pods in CLBO state during CSM install.

    • When installing CSM 1.6, cray-shared-kafka-kafka- pods in the services namespace fail to come up which results in cfs-api pods in CLBO state.
    • A workaround is presented in CFS API pods in CLBO.
