There is no real "taking proper account of them" for the programmer to
do, other than that to get maximum use you need to have at least as
many concurrent threads of program as there are cores/hyperthreads/
whatever. In otherwords, at least the number returned by
availableProcessors().
Optimizations for the details of the specific hardware architecture's
details are for the JIT.
Only JVM coders need concern themselves with these.
