#2364 (HPC-04_mcastril_Mixed_Precision_implementation) – NEMO

Opened 4 years ago

Closed 3 years ago

Last modified 22 months ago

#2364 closed Task (fixed)


Reported by: mcastril Owned by: mcastril
Priority: low Milestone: Unscheduled
Component: env Version: trunk
Severity: major Keywords: hpc mixed_precision performance


This action is a follow up from HPC-08_Mixed_precision in 2018 WP. It was linked to two tickets (#2039 and #2040), that were respectively devoted to the assessment and implementation of Mixed Precision in NEMO. After the evaluation stage has been completed (together with the preparation of the necessary tools to do the mentioned assessment and the implementation), this year will be time for the implementation.

Oriol Tintó (oriol.tinto@…) is the Principal Investigator for the whole task. ECMWF is a collaborator for this phase and will have a principal role on the validation in coupled simulations.
