Sep 1, 2025September 2025: Delivered metrics calculation API improvements and refactors for intel/compute-runtime, focusing on reliability, scalability, and clarity of reporting. Centralized IP sampling calculation via IpSamplingCalculation, removed pOffset from API, added final and usedSize, and reordered metric scope initialization/aggregation by ID to ensure deterministic results across multi-device setups. These changes pave the way for multi-device metrics, stronger data validation, and easier maintenance.
