/AWS1/CL_SGMCLUSTTIEREDSTRGCFG

Defines the configuration for managed tier checkpointing in a HyperPod cluster. Managed tier checkpointing uses multiple storage tiers, including cluster CPU memory, to provide faster checkpoint operations and improved fault tolerance for large-scale model training. The system automatically saves checkpoints at high frequency to memory and periodically persists them to durable storage, like Amazon S3.

CONSTRUCTOR

IMPORTING

Required arguments:

iv_mode TYPE /AWS1/SGMCLUSTERCONFIGMODE /AWS1/SGMCLUSTERCONFIGMODE

Specifies whether managed tier checkpointing is enabled or disabled for the HyperPod cluster. When set to Enable, the system installs a memory management daemon that provides disaggregated memory as a service for checkpoint storage. When set to Disable, the feature is turned off and the memory management daemon is removed from the cluster.

Optional arguments:

iv_instmemoryallocpercentage TYPE /AWS1/SGMCLSTINSTMEMALLOCPER00 /AWS1/SGMCLSTINSTMEMALLOCPER00

The percentage (int) of cluster memory to allocate for checkpointing.
