Dennis Abts
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. Abts has technical publications and patents in the areas of interconnection networks, data-center networking, cache-coherence protocols, high-bandwidth memory systems, and supercomputing. He received his Ph.D. in Computer Science from the University of Minnesota, and is a member of the Association for Computing Machinery and IEEE Computer Society.
