1. Presentations

During the meeting we have discussed about the adoption and the maintainability of the Mixed Precision implementation of NEMO. Two presentations have been discussed:

  • NEMO 4.0 performance evaluation on NEC SX-Aurora TSUBASA (Eric Maisonneive)
  • Preliminary evaluation of impact of the tiling and loop fusion on the computational performance of NEMO 4.2rc: (Daley Calvert + Francesca Mele)

(see attached slides)
