Dennis Abts is a Member of Technical Staff at Google, where he is involved in the system architecture and design of next-generation large-scale clusters. His research interests include scalable coherence protocols, memory consistency models, interconnection networks, fault tolerant computing and robust system design. Prior to joining Google, Dennis was a Sr. Principal Engineer and System Architect for Cray Inc. where he was principally involved with the architecture and design of several large-scale parallel computers over the span of his 10+ year tenure at Cray. Including, the Cray XT3 and XT4 (Red Storm), Cray X1, Cray BlackWidow (XT5), and next-generation systems sponsored by the DARPA HPCS initiative.
