\usage{
freeCores(
memory = c("5min", "15min", "1min"),
fraction = 0.9,
logical = getOption2("parallelly.availableCores.logical", TRUE),
default = parallelly::availableCores()
)
}
\arguments{
\item{memory}{(character) The time period used to infer the system load,
with alternatives being 5 minutes (default), 15 minutes, or 1 minute.}
\item{fraction}{(non-negative numeric) A scale factor.}
\item{logical}{Passed as-is to \code{\link[=availableCores]{availableCores()}}.}
\item{default}{(integer) The value to be returned if the system load is
unknown, i.e. \code{\link[=cpuLoad]{cpuLoad()}} return missing values.}
}
\value{
An positive integer with attributes \code{loadavg} (named numeric),
\code{maxCores} (named integer), argument \code{memory} (character), and
argument \code{fraction} (numeric).
