In this section there are some traces that show in which MPI state threads are. For example: running, waiting, sending, etc. We just analyzed one coupling iteration due to the fact that this kind of trace is very huge and, as a consequence, difficult to handle it. Note that the original trace contains more information, like IPC, useful duration, cycles, etc. The trace is available on /gpfs/projects/bsc32/share/traces/EC-Earth_3.2beta/complete_1cplng_iter_with_northfold_opt_ifs-128_nemo-128 (MareNostrum).
