trunk/0551aed30479d790a23d1d19ec81e8dc79bb7965: Submodule Bump Flash to fix int64 striding (#175184)
A critical fix for handling massive datasets with 64-bit integers improves stability.
Deep Dive
The PyTorch team merged a fix (commit 0551aed) to the Flash Attention submodule, resolving an issue with 'int64 striding' (PR #175184). This technical patch corrects how the system handles memory access patterns for very large tensors. For developers, it means more reliable training runs when working with massive datasets or models that exceed standard 32-bit integer limits, preventing potential crashes or incorrect computations.
Why It Matters
Ensures stability for training next-gen LLMs and diffusion models on huge datasets, a foundational need for AI research.
