Parallel Backend — parallel.backend • AutoSpectral

Sets up parallel processing backend using parallel and parallelly to establish PSOCK clusters on Windows. Sets up clusters, defines parLapply-based function.

Usage

parallel.backend(
  asp,
  exports,
  threads,
  export.env = parent.frame(),
  dev.mode = FALSE,
  package.path = NULL
)

Arguments

asp: The AutoSpectral parameter list.
exports: The vector of variables and functions to pass to the clusters.
threads: Numeric, number of threads to use for parallel processing.
export.env: The environment containing other functions and global variables potentially needed by the clusters.
dev.mode: Logical, allows testing of function while in development. Default is FALSE.
package.path: File.path to the R package files for AutoSpectral to permit loading of the functions via devtools::load_all() while in dev.mode.

Value

An lapply function, either based on parLapply if parallel backend initialization was successful or using sequential lapply if not.
