Switched GW-Links in large scale Pod systems

This technical note describes the use of switched GW-Links to connect Bow-2000 IPU-Machines together in large scale (Bow Pod₂₅₆ and larger) Bow Pod systems. This is in contrast to our approach for smaller-scale Bow Pod systems which use directly connected horizontal GW-Links between Bow-2000s.
