The user-accessible memory on Aurora compute nodes will be reduced by the equivalent of a node's HBM capacity (128GB) on Monday, June 23, 2025, to approximately 960GB between DDR5 + HBM, regardless of how applications utilize each memory tier. The 768GB of GPU memory is unaffected and is not being restricted in any way.
