DESCRIPTION:By: Mark D. Hill - University of Wisconsin-Madison\n\nAbstract
 :\nComputer system performance has improved due to creatively using more t
 ransistors (Moore’s Law) in parallel via bit-\, instruction-\, thread-\,
  and data-level parallelism. With the slowing of technology scaling\, the 
 only known way to further improve computer system performance under energy
  constraints is to employ hardware accelerators. Each accelerator is a har
 dware component that executes a targeted computation class faster and usua
 lly with (much) less energy. Already today\, many chips in mobile\, edge a
 nd cloud computing concurrently employ multiple accelerators in what we ca
 ll accelerator-level parallelism (ALP).\n \nThis talk develops our hypoth
 esis that ALP will spread to computer systems more broadly. ALP is a promi
 sing way to dramatically improve power-performance to enable broad\, futur
 e use of deep AI\, virtual reality\, self-driving cars\, etc. To this end\
 , we review past parallelism levels and the ALP already present in mobile 
 systems on a chip (SoCs). We then aid understanding of ALP with the Gables
  model and charge computer science researchers to develop better ALP “be
 st practices” for: targeting accelerators\, managing accelerator concurr
 ency\, choreographing inter-accelerator communication\, and productively p
 rogramming accelerators. This joint work with Vijay Janapa Reddi of Harvar

 io:\nMark D. Hill is John P. Morgridge Professor and Gene M. Amdahl Profes
 sor of Computer Sciences at the University of Wisconsin-Madison\, where he
  also has a courtesy appointment in Electrical and Computer Engineering. H
 is research interests include parallel-computer system design\, memory sys
 tem design\, and computer simulation. He received the 2019 Eckert-Mauchly 
 Award and is a fellow of IEEE and the ACM. He serves as Chair of the Compu
 ter Community Consortium (2018-19) and served as Wisconsin Computer Scienc
 es Department Chair 2014-2017. Hill has a PhD in computer science from the
  University of California\, Berkeley.\n\nMore information\n\n
