SUMMARY:High-Performance Programming and Execution of a Coral Biodiversity
  Mapping Algorithm Using Chapel
DESCRIPTION:Scott Bachman (National Center for Atmospheric Research (NCAR)
 ), Rebecca Green (The Coral Reef Alliance), Anna Bakker (University of Mia
 mi), Helen Fox (The Coral Reef Alliance), Sam Purkis (University of Miami)
 , and Ben Harshbarger (Hewlett Packard Enterprise (HPE))\n\nWe will demons
 trate how the parallelism and expressiveness of the Chapel programming lan
 guage are used to achieve an enormous improvement in computational speed f
 or a problem related to coral reef conservation. Chapel’s concise syntax a
 nd versatile data structures enable this problem to be solved in under 300
  lines of code, while reducing the time to solution from days down to the 
 order of seconds. This improvement is so substantial that it represents a 
 paradigm shift in the way biodiversity can be measured at scale, providing
  a wealth of novel information for marine ecosystem managers and opening u
 p brand new avenues for scientific inquiry. This paper will review the sol
 ution strategy and data structures in Chapel that allowed these improvemen
 ts to be realized, and will preview future extensions of this work that ha
 ve been made possible by this drastic speedup.\n\nTag: Accelerators, Artif
