Comparision 18/02/2016

18/02/2016: revisions trunk 2916 and MICT 3161 were considered to be equivalents.

The same run.def file is used to compare both developments.

The simulations were carried out under the following conditions:

• 1 Year
• Global
• CRU-NCEP v5.3.2 (6 hourly)
• CURIE
• IO library: IOIPSL
• Compilation mode IOIPSL: production
• Compilation mode Orchidee: production

Mict R3161

Time table:

N procs	4	8	16	32	64	128
0.5 deg	Memory error	>16h39 322 days	13h00	8h46	6h35	5h38
1 deg	6h37	4h20	2h36	1h45	1h21	1h08
2 deg	1h40	56	35	24	19	16

Note: 0.5 deg in 4 N procs did not start due to memory requirements. 0.5 deg in 8 N procs could not finish the simulation in the maximum time given by the HPC. It stopped at the simulation day 322. Both values can be extrapolated.

Trunk R2916

The same simulations with the same options where carried out with the following results:
