DESCRIPTION:Solving differential equations at the exascale Garth N. Wells
 \, University of Cambridge Abstract: I will discuss the development of f
 inite element algorithms and implementations for a range of applications
  on exascale hardware. When considering accelerators it is helpful to re
 flect on past attempts (since the honest efforts generally failed!) to a
 ssess why performance was disappointing. I will argue that the disappoin
 ting performance was due to a failure to assess the suitability of algor
 ithms end-to-end\; focusing on accelerating one step in a sequence of ot
 herwise established of algorithms over-constrains approaches and dooms t
 hem to failure. Improved mathematical and algorithmic understanding now 
 allows us to exploit exascale-type hardware efficiently. Also on the ups
 ide\, I will show that recent developments in compiler technologies have
  made it much easier to develop high performance finite element kernels 
 without non-standard language extensions\, with excellent measured perfo
 rmance assessed against performance models. To make developments accessi
 ble\, I will also touch upon the open-source FEniCS Project (https://eur
