apollo (version 0.1.0)

apollo_makeCluster: Creates cluster for estimation.

Description

Creates cluster and loads pieces of the database for each worker.

Usage

apollo_makeCluster(
  apollo_probabilities,
  apollo_inputs,
  silent = FALSE,
  cleanMemory = FALSE
)

Arguments

apollo_probabilities

Function. Returns probabilities of the model to be estimated. Must receive three arguments:

• apollo_beta: Named numeric vector. Names and values of model parameters.

• apollo_inputs: List containing options of the model. See apollo_validateInputs.

• functionality: Character. Can be either "estimate" (default), "prediction", "validate", "conditionals", "zero_LL", or "raw".

apollo_inputs

List grouping most common inputs. Created by function apollo_validateInputs.

silent

Boolean. If TRUE, it reports progress to the console. Default is FALSE.

cleanMemory

Boolean. If TRUE, it saves apollo_inputs to disc, and removes database and draws from the apollo_inputs in .GlobalEnv and the parent environment.

Value

Cluster (i.e. an object of class cluster from package parallel)

Details

Internal use only. Called by apollo_estimate before estimation. AT least doubles up memory usage. But during the splitting it uses even more (~250
