OASIS3 coupled models

  • High Resolution NEMO – LMDz (IPSL):

SGI ALTIX ICE (CINES)
LMDz ~1/3 deg, 589 Kpts, 39 vertical levels
NEMO ORCA0.25, 1.5 Mpts, 75 vertical levels
Run with 2191 cores: 2048 LMDz, 120 NEMO, 23 OASIS3 : overhead not precisely evaluated

  • High resolution EC-Earth:

Ekman cluster (Stockholm) : 1268 nodes (each with 2 quadripro AMD Opteron)
IFS T799, 843 Kpts, 62 vertical levels
NEMO ORCA0.25, 1.5 Mpts, 45 vertical levels
20 coupling fields
Coupling frequency: 3 hours
Run with 1057 cores: 800 IFS, 256 NEMO, 1 OASIS3: 11% elapse overhead
Run with 1066 cores: 800 IFS, 256 NEMO, 10 OASIS3: 1.3% elapse overhead
(Run with 1546 cores: 1280 IFS, 256 NEMO, 1 OASIS3: 6% elapse overhead)

  • UK Met Office / Hadley Centre:

Platform: IBM power6 machines (AIX)
Low resolution NEMO/CICE – UM : operationally used for seasonal forecasts
24 hour coupling
Total of 3 nodes (96 PEs)90 PEs for UM ~ 1 deg atmopshere
5 PEs for NEMO/CICE (ORCA1)
1 PEs for OASIS3
High resolution NEMO/CICE – UM : 3 hour coupling
38 coupling fields (20 from the atmosphere to the ocean and 18 from the ocean to the atmosphere)
Total of 9 nodes (288 PEs)192 PEs for UM ~ 2/3 deg atmopshere, 432×325 = 140 Kpts, 85 vertical levels
88 PEs for NEMO/CICE (ORCA0.25) : 1.5 Mpts, 75 vertical levels
8 PEs for OASIS3
Exchange through the master process only as it was observed to be significantly faster than when each process sends its part of the coupling field to the OASIS3 processes
Less than 2% overhead
