SUMMARY:To the Exascale, and Beyond: Computing Challenges in Lattice QCD
DESCRIPTION:Minisymposium\n\nTo the Exascale, and Beyond: Computing Challe
 nges in Lattice QCD\n\nClark\n\nAs we move to the Exascale, computational 
 science will have access to an unprecedented amount of computational power
 .  However, unlike prior generational leaps in performance, harnessing tha
 t power will be much more demanding, requiring more than the prior mantra 
 of exposing more parallelism.  Driven by diminising returns from Moore's L
 aw, the increasingly hierarchical nature of supercomputing, with increased
  emphasis on locality, will demand significant refactoring of algorithms a
 nd workflows.  Moreover, with increased investment in low-precision throug
 hput, driven by the explosion of artifical intelligence, the full apprecia
 tion of Exascale-era processors will require precision-hardening of algori
 thms.  We discuss the challenges facing Lattice QCD in this new era, and d
 escribe the type of evolutionary and revolutionary changes that are ongoin
 g in order meet these challenges.\n\nDomain: Physics
