Here are runtimes for the full Oregon Metro example
INFO - activitysim.core.tracing - Time to execute run_model aggregate_demographics_processor : 2.42 seconds (0.0 minutes)
INFO - activitysim.core.tracing - Time to execute run_model aggregate_zone_processor : 1.826 seconds (0.0 minutes)
INFO - activitysim.core.tracing - Time to execute run_model aggregate_od_processor : 1596.351 seconds (26.6 minutes)
INFO - activitysim.core.tracing - Time to execute run_model link_daily_processor : 270.826 seconds (4.5 minutes)
INFO - activitysim.core.tracing - Time to execute run_model write_data_dictionary : 0.11 seconds (0.0 minutes)
INFO - activitysim.core.tracing - Time to execute run_model write_tables : 0.438 seconds (0.0 minutes)
INFO - activitysim.core.tracing - Time to execute run (6 models) : 1872.208 seconds (31.2 minutes)
INFO - activitysim.core.tracing - Time to execute all models : 1872.239 seconds (31.2 minutes)
The cache_skims setting in aggregate_od.yaml lets you trade off RAM versus runtime. For example:
cache_skims: True Time to execute all models : 718.714 seconds (12.0 minutes) aggregate_od mem after assign_variables, memory_info: vms: 65.67 GB rss: 65.68 GB uss: 65.93 GB
cache_skims: False INFO - activitysim.core.tracing - Time to execute all models : 981.126 seconds (16.4 minutes) aggregate_od mem after assign_variables, memory_info: vms: 20.3 GB rss: 20.32 GB uss: 20.39 GB
it would be good to speed up the slow processors - most likely the od processor. We can test with the full Oregon Metro example data set and set of expressions.
