Description
SystemInfo::numCores is less useful than might be desired, because many forms of process management can limit access to a subset of total cores. This causes us to scale certain internal subsystems at suboptimal levels by assuming more processing than we actually have available.
It would useful to have a new value available, perhaps numAvailableCores, which would return a num <= ::numCores.
Consider the implementation of gnu nproc and investigate if a portable solution exists.
