Merged Matthieu Schaller requested to merge proxy_work2 into master Nov 13, 2018
  • Overview 18
  • Commits 16
  • Changes 6

Three main changes:

  • Loop over neighbouring cells in the same way when making proxies, constructing hydro tasks and gravity tasks,
  • Use a symmetry condition to reduce the number of proxies on a given node,
  • Use a better calculation of the distance between future multipoles to decide whether to construct a proxy or not.

Overall this reduces the number of gravity proxies by a factor 6 or so on the EAGLE-50 example.
