 +======Scale-Out Processors======

 +A growing number of today’s most relevant applications are served
 +online and run in large-scale datacenters characterized by thousands
 +of servers and multi-megawatt power budgets. As Dennard scaling comes
 +to a halt, experts are projecting exponential growth in datacenter
 +power and performance requirements in the coming decade, driven by the
 +rising popularity of the online service model. To efficiently meet the
 +computing needs in the post-Dennard era, datacenters will rely on a
 +new form of ISA – Integration,​ Specialization,​ and Approximation.\\
 +As a first step toward this post-Dennard ISA, we have developed
 +Scale-Out Processors – a processor design methodology that maximizes
 +performance per TCO on scale-out workloads running in large-scale
 +datacenters. Using a metric of performance density, our methodology
 +facilitates the design of optimal configurations,​ called pods, of
 +cores, caches, and interconnect. Each pod is a stand-alone
 +server-on-chip,​ a feature that avoids the expense and complexity of
 +global (i.e., inter-pod) interconnect and coherence. As I will
 +demonstrate,​ Scale-Out Processors yield higher performance,​ lower TCO,
 +and better technology scalability over existing design alternatives.
 +Boris Grot is a post-doctoral researcher in the Parallel Systems
 +Architecture Lab at EPFL. His research focuses on improving the
 +efficiency of large-scale datacenters through advancements to server
 +processor architectures,​ memory systems, and  interconnects. Grot
 +received his PhD in Computer Science from The University of Texas at
 +Austin in 2011. His thesis addressed challenges of scalability and
 +quality-of-service in on-chip networks of highly-integrated processor
