- Jun 11, 2025 Shuffle Fault Tolerance: Recomputing Lost Map Output Why map output is an unreplicated cache on local disk, what a lost segment costs downstream, and how lineage and shuffle services change the recovery path. data engineering
- Mar 25, 2024 Activation Checkpointing: Trading Recomputation for Stored Tensors How discarding activations at segment boundaries and recomputing them in backward reduces memory, what the extra forward pass costs, and where the optimal segment count falls. deep learning
