Ring Attention
Definition
Ring Attention distributes attention computations over a ring of devices.
A method for distributed, block-wise computation of exact attention over long sequences, where key and value blocks are passed around in a ring between devices.
Simply explained
Computers pass data blocks in a circle and each processes its part of the joint computation.
Why it matters in practice
The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.
Example from business
Multiple accelerators share the KV context and compute global attention section-wise.
Limits and pitfalls
- Ignoring communication, load balancing, and hardware topology, portraying scalability as automatic acceleration, or falsely labeling Ring Attention as approximate attention.
Origin & history
Liu and co-authors published Ring Attention in 2023.
Use in mid-sized companies
- Possible application: Multiple accelerators share the KV context and compute global attention section-wise.
