Set a doFuture execution strategy

Description

Set a doFuture execution strategy

Usage

set_doFuture_strategy(
  strategy = c("sequential", "multisession", "multicore", "mixed"),
  n_workers = NULL
)

Arguments

strategy

One of "sequential" (default), "multisession", "multicore", or "mixed".

n_workers

A positive numeric scalar or a function specifying the maximum number of parallel futures that can be active at the same time before blocking. If a function, it is called without arguments when the future is created and its value is used to configure the workers. The function should return a numeric scalar. Defaults to future::availableCores()-1 if NULL (default), with "multicore" constraint in the relevant case. Ignored if strategy=="sequential".

Value

The appropriate get_doFuture_operator() operator to use in a foreach::foreach() loop. The %do% operator is returned if strategy=="sequential". Otherwise, the %dopar% operator is returned.

Examples

`%fun%` <- set_doFuture_strategy("multisession", n_workers=3)
# perform foreach::foreach loop using the %fun% operator
end_doFuture_strategy()
