guessNumCores

Guess Number of Cores

Description

Attempts to guess the number of CPU ‘cores’, both physical and logical.

Usage

guessNumCores(logical = FALSE)

Arguments

logical

A logical value. When FALSE, an estimate of the number of physical cores is returned. When TRUE, so-called "logical" cores as also included.

Details

Because of different definitions of cores used by different manufacturers, the distinction between logical and physical cores is not universally recognized. This function will attempt to use operating system definitions when available, which should usually match the CPU itself.

Value

An integer, or NA if no clear answer was obtained.
