r-cran-parallelly binary package in Ubuntu Noble amd64

 Utility functions that enhance the 'parallel' package and support the
 built-in parallel backends of the 'future' package. For example,
 availableCores() gives the number of CPU cores available to your R
 process as given by R options and environment variables, including those
 set by job schedulers on high-performance compute clusters. If none is
 set, it will fall back to parallel::detectCores(). Another example is
 makeClusterPSOCK(), which is backward compatible with
 parallel::makePSOCKcluster() while doing a better job in setting up
 remote cluster workers without the need for configuring the firewall to
 do port-forwarding to your local computer.
