setup_RNG: Organizing previous state and streams of random number...

In Burke-Lauenroth-Lab/SoilWat_R_Wrapper: Simulation Framework for SOILWAT2

Description

Organizing previous state and streams of random number generator

Usage

setup_RNG(streams_N, global_seed = NULL, reproducible = TRUE)

Arguments

streams_N	An integer value representing the number of tasks for which RngStreams according to Pierre L'Ecuyer should be generated.
global_seed	A vector appropriate for .Random.seed of the current RNG; a single integer or NULL that will be passed to set.seed.
reproducible	A logical value. If TRUE, then streams_N are prepared. If FALSE, then instead NAs are returned.

Value

A list with four elements:

• seed_prev captures the previous state of the RNG seed.

• RNGkind_prev captures the previous kind of the RNG.

• global_seed is the seed used to set the RNG for stream generation.

• seeds_runN is a list with a stream of streams_N seeds.

• seeds_DS is an empty list – a placeholder for a list with a stream of seeds for climate scenario downscaling.

Usage

RNG - parallelized function calls by rSFSW2

• try_MonthlyScenarioWeather wraps calc_MonthlyScenarioWeather which calls set_RNG_stream to prepare RNG for functions

  • fix_PPTdata_length

  • calc_Days_withLoweredPPT

  • controlExtremePPTevents

• do_OneSite calls set_RNG_stream to prepare RNG for functions

  • calc_TimeToGerminate

Note

Parallelized function calls without using RNG

• ISRICWISE5minV1b_extract_SUIDs

• ISRICWISE5minV1b_try_weightedMeanForSimulationCell

• collect_EnsembleFromScenarios

• missing_Pids_outputDB

• gribDailyWeatherData

• writeDailyWeatherData

• gribMonthlyClimate

• writeMonthlyClimate
