Performance evaluation of ZOMA preemptive deadlock recovery mechanism for wormhole networks

摘要

This paper presents a novel deadlock recovery mechanism for fully adaptive routing in wormhole interconnection networks and its performance evaluation using simula- tion modeling. ZOMA is an efficient mechanism that takes advantage of the concept of wormhole switching in terms of low hardware resource requirements. The perfor- mance of the new mechanism can match that of other more expensive deadlock-recovery mechanisms, while requir- ing lower hardware resources that are not on the critical path of the switching process.
