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). 18 18 19 The following graphs show the model rate (in model years per day) against cost and againsttotal number of processes. Each point in the graph is the result of running the coupled suite for a model month. The cost of computing the graph was 440 kAU.19 The following graphs show the model rate (in model years per day) against cost and total number of processes.
