DESCRIPTION:Title:  "It’s All About Energy:  What it Takes to do a FLO
 P in Real Systems”  \nAbstract:  Artificial Intelligence is based on c
 omputing\, which consumes energy. As natural energy resources become more 
 expensive and AI demands higher performance\, the market naturally rewards
  computer architectures that deliver greater energy efficiencies.  This t
 alk looks at where energy goes in two real systems doing AI in very differ
 ent environments:  the IBM922 server\, advertised on their website as “
 The best server enterprise AI\,” and the Snapdragon 845 system-on-a-chip
 \, used in the Samsung Galaxy S9 and many other Android mobile phones.  I
  will walk through what it takes to do a single floating-point operation i
 n each system\, from getting the data in memory\, physically through the p
 ackage\, board/substrate\, on-chip wires\, cache SRAM\, register file\, un
 til finally reaching the ALU.  Because the two systems were designed for 
 very different markets and are at totally different scale\, they achieve c
 ompletely different levels of energy efficiency.  \nBio:  Peter Hsu rece
 ived Ph.D. from University of Illinois Urbana-Champaign. He started at IBM
  T. J. Watson Research Center on the 801 Project.  He joined SGI in 1990 
 as architect of MIPS R8000 TFP microprocessor\, shipping 1994 in fifty TOP
 500 supercomputers.   Peter co-founded ArtX 1997\, developer of Nintendo 
 GameCube.  ArtX acquired by ATI Technology in 2000.  After attending art
  school and learning to paint\, Peter joined Oracle Labs 2011 as Architect
  on the RAPID project and built a 50K-thread parallel SQL database acceler
 ator.  Peter is currently visiting research at EPFL University in Switzer
 land and Consulting Computer Architect at Barcelona Supercomputing Center.
