# The Monte Carlo tool uses a double execution of the S-main:
|
||
|
|
# - pass #1 uses the scenario input.py file to process the variables identified
|
||
|
|
# for dispersion. A specified number, N, of values {v_1, ..., v_N} is
|
||
|
|
# generated for each variable v, with the values constrained by the specified
|
||
|
|
# distribution of v; N is specified in the input file.
|
||
|
|
# A set of N files, {RUN_1/monte_input.py, ... , RUN_N/monte_input.py} is
|
||
|
|
# created, with each file containing one of the set of values for each
|
||
|
|
# variable. Once these files are generated, the simulation is complete for
|
||
|
|
# pass #1 and it terminates.
|
||
|
|
# - pass #2 uses one of the generated files (monte_input.py) as the input file
|
||
|
|
# for a regular execution of the simulation. There will typically be many
|
||
|
|
# executions of the sim, one for each of the generated monte_input.py files.
|
||
|
|
|
||
|
|
# This input file provides one example of how to test this two-pass process,
|
||
|
|
# although it is admittedly a bit convoluted and hard to read. TODO: Once
|
||
|
|
# TrickOps is capable of operating with this monte-carlo implementation, that
|
||
|
|
# framework can manage both the generation and local execution of generated
|
||
|
|
# monte_input.py files, removing the need for this type of "sim that launches a
|
||
|
|
# sim" test methodology -Jordan 10/2022

|
# For the purpose of expedient testing, we generate and run only 2 files.
