Despite the fact that DEC Ada on VAX uses a private tasking engine:

DEC Ada on Alpha VMS uses the common DECthreads engine also used by
the C-oriented pthreads and the (language-neutral-except-for-Ada ?)
DECthreads interface.  That engine was upgraded for VMS V7 to use
kernel threads but only fully enabled with a VMS patch kit for V7.0
or without any patch kit in V7.1.

At least that was DEC's announced plan.

So at what operating system version are you unable to used multiple
processors from a single Ada program ?  Has DEC departed from their
stated intentions which I listed above ?

(I don't have a multiprocessor system to test these assertions.)
