A more detailed view of u-as037 (r 61036) running on ARCHER
This looks at the performance of HadGEM3-GC3.1 N96ORCA1 PI Control for CMIP6 over a wide range of atmosphere decompositions with a fixed number of IO servers (6). The model was run on ARCHER in December, 2017. The ocean decomposition was 9x8 and the XIOS used 6 processes. The atmosphere was run with two threads, except for one run at 36x28 where three threads were used (3,186 processes in the graph below).
The following graphs show the model rate (in model years per day) against cost and total number of processes. Each point in the graph is the result of running the coupled suite for a model month. The cost axis was obtained by rescaling the processors axis in the lower graph. The cost of computing the graph was 440 kAU.
