Parallelize the execution of a function over a list of arguments values

Usage

executeInParallel(
  fun,
  firstArguments,
  exports = NULL,
  ...,
  outputNames = NULL,
  nrOfCores = ospsuite::getOSPSuiteSetting("numberOfCores")
)

Arguments

fun

A function that will be called with different arguments values

firstArguments

A list of the values of the first argument of the function. The function will be called n times where n is the number of entries in firstArguments

exports

Names of the objects in the calling environment that the function relies on that are not passed as arguments. May be NULL (default).

...

Further arguments of the function.

outputNames

Optional: a list of names used for the output list. Result of each execution of fun will be named with the name having the same index in outputNames as as the argument value in firstArguments. If specified, outputNames must have the same length as firstArguments

nrOfCores

Optional: the maximal number of parallel threads. By default the value defined in ospsuite::getOSPSuiteSetting("numberOfCores") is used, and equals the number of logical cores minus 1.

Value

A list containing the outputs of the function fun iterated over the values in firstArguments.
