Abstract: In the many-core era, scalable coherence and on-chip interconnects are crucial for shared memory processors. While snoopy coherence is common in small multicore systems, directory-based coherence is the de facto choice for scalability to many cores, as snoopy relies on ordered interconnects which do not scale.

•SCORPIO: A 36-core shared-memory processor Snoopy coherency on a mesh interconnect: –Runtime: 24% better than LPD, 13% better than HT –Cost: 28.8W @ 833MHz •Novel network-on-chip for scalable snoopy coherence New ideas: –Distributed in-network ordering mechanism –Decouple message delivery from message ordering Contributions

We present SCORPIO, an ordered mesh Network-on-Chip (NoC) architecture with a separate fixed-latency, bufferless network to achieve distributed global ordering. Message delivery is decoupled from the ordering, allowing messages to arrivein any order and at any time, and still be correctly ordered.
