T799L91-ORCA025L75

The table below gives some reference values for wallclock per job *per 1 month of simulation*, for the three most commonly used platforms. The first value is for the standard resolution T255L91-ORCA1L46, and the second value for the high resolution T511L91-ORCA025L75. The values for the parallel jobs, i.e. for the SIM, depends on the number of processors (the more the processors the less the wallclock time); here the wall clock for the SIM corresponds to job with processors as suggested above (or, have values close to them), but for clarity it is also mentioned in the table.
