RainfallModel.update_simulation_config(default_block_size=1000, check_block_size=True, minimum_block_size=10, check_available_memory=True, maximum_memory_percentage=75, block_subset_size=50, spatial_buffer_factor=15)

Update default configuration settings for simulation.

Parameters:

  • default_block_size (int) – Number of years (maximum) to simulate at once to avoid memory issues.

  • check_block_size (bool) – Flag to indicate whether code should automatically check whether the default_block_size (probably) needs to be reduced to avoid memory issues (see check_available_memory and maximum_memory_percentage).

  • minimum_block_size (int) – Minimum number of years to simulate at once.

  • check_available_memory (bool) – Flag to indicate whether current system memory usage should be checked to limit the maximum amount of memory assigned in simulation.

  • maximum_memory_percentage (int or float) – Maximum percentage of system memory that may be assigned by a simulation. If estimated memory usage exceeds this percentage then a smaller block size will be tried until the minimum_block_size is reached.

  • block_subset_size (int) – Block subset size (number of years) for internal use in discretisation (as it is much faster to discretise subsets of each block).

  • spatial_buffer_factor (float) – Number of standard deviations of raincell radius distribution to use with buffer method of spatial raincell simulation.
