摘要

Avoiding routing deadlock is an important component of an interconnection network. For large-scale systems with high-radix topologies that leverage non-minimal adaptive routing, virtual channels (VCs) are commonly used to prevent routing deadlock. However, VCs in large-scale networks can be costly because of deep buffers and restrict VC usage. In this work, we propose BoomGATE for deadlock avoidan...
