What is recorded here?
Sharded tokens across devices and used all-to-all redistribution to give each device full sequence access for a subset of attention heads, followed by inverse redistribution and ZeRO-compatible training.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Inherits sequence/model parallelism, ZeRO and attention kernels. Constant communication volume assumes proportional sequence/device scaling in the paper's model; it is not constant end-to-end runtime. Head-count divisibility/scalability and network topology matter. Original seven-author Microsoft report controls attribution.
