MAS-Output

This page is part of the Multi Agent System (MAS) documentation.
It contains an overview of MAS-related PALM output.
For an overview of all MAS-related pages, see the MAS main page.

There are four kinds of MAS-related data that can be used to analyse MAS-runs.

• NetCDF Output
  All agent output data is written to the file DATA_AGT_NETCDF.

• Warning Message
  During a PALM run using the MAS a warning message (PA0420) can occur (in the console or job protocol). If this is the case, DATA_AGT_NETCDF will be missing data. Use the informative message PA0457 to adjust the allocated file size prior to your next simulation

• Informative Message
  At the end of each PALM run using the MAS an informative message (PA0457) about the maximum number of agents during the simulation is given (in the console or job protocol). Use it to adjust dim_size_agtnum_manual to save memory or avoid data loss during your next simulation.

• CPU_MEASURES
  
  • mas Total MAS run time
  • mas_data_output MAS data output (high rms is expected as output is done on one PE only)
  • mas_move_exch_sort Moving agents to their respective grid cells, exchange between PEs and sorting of agent arrays
  • mas_social_forces Agent interaction with obstacles and each other
  • mas_timestep Time integration of Agent velocities and positions

NOTE: Large load imbalances between PEs are very possible when using the MAS. This results from the utilized storage scheme.
