DESCRIPTION:David Wentzlaff\, Assistant Professor at Princeton University\
 nCurrent-day data centers and IaaS clouds (e.g. Amazon EC2\, MS Azure\, Go
 ogle GCE) use microprocessors that are very similar to or the same as thos
 e used in small servers and desktops.  This work rethinks the design of m
 icroprocessors specifically for data center use along with how microproces
 sors are affected by the novel economic models that have been popularized 
 by IaaS clouds.  This talk will describe several architectural changes in
 cluding how a processor can be decomposed into sub-components (e.g. ALU\, 
 Cache\, Fetch Unit) that can be individually rented in IaaS clouds\, how r
 unning similar programs can be taken advantage of in the data center\, how
  architectural features such as the flavor of memory bandwidth (bursty vs.
  bulk) can be provisioned and sold in the data center\, and novel memory a
 rchitectures that enable the creation of sub-coherence domains of cache co
 herence across the data center.  This work has not only been simulated\, 
 but many of the discussed ideas have been implemented in one of the larges
 t academic processors ever built\, the Princeton Piton Processor.  Piton 
 is a 25-core manycore built in IBM's 32nm process technology containing ov
 er 460 Million transistors and runs full stack Debian Linux with networkin
 g.   This talk will discuss Piton along with what it takes to tape-out a
  complex microprocessor in an academic setting.  Last\, Piton has been re
 cently open sourced as the OpenPiton (http://www.openpiton.org) project wh
 ich is a expandable manycore platform which includes RTL\, thousands of te
 sts\, and implementation scripts.  The talk will conclude by discussing h
 ow OpenPiton is able to contribute to the burgeoning field of open source 
 hardware.
