The Alpha 21364 network architecture
TL;DR: The Alpha 21364 processor provides a high-performance, highly scalable, and highly reliable network architecture that provides a variety of reliability features, such as per-flit ECC, that make the network well-suited to support communication-intensive server applications.
Journal ArticleDOI
The Alpha 21364 network architecture
TL;DR: The Alpha 21364 processor provides a high-performance, scalable, and reliable network architecture with a router that runs at 1.2 GHz and has a peak bandwidth of 22.4 Gbytes/s.
Proceedings ArticleDOI
A comparative study of arbitration algorithms for the Alpha 21364 pipelined router
Shubhendu S. Mukherjee,Federico Silla,Peter J. Bannon,Joel Emer,Steve Lang,David Wightman Webb +5 more
TL;DR: A new arbitration algorithm called SPAA (Simple Pipelined Arbitration Algorithm), which is implemented in the Alpha 21364 processor's on-chip router pipeline, and a new prioritization policy called the Rotary Rule, which prevents the network's adverse performance degradation from saturation at high network loads.
