Jobs are spawned asynchronously using the functions
mccollect (both in parallel).
Does not work on Windows, use
makeClusterFunctionsMulticore(ncpus = NA_integer_, fs.latency = NA_real_)
Number of CPUs.
Default is to use all logical cores. The total number of cores "available" can be set via the option
and defaults to the heuristic implemented in
Expected maximum latency of the file system, in seconds.
Set to a positive number for network file systems like NFS which enables more robust (but also more expensive) mechanisms to
access files and directories.
Usually safe to set to
NA to disable the heuristic, e.g. if you are working on a local file system.
