    17 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 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). 
     17This 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).

    1919The 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.
