basic question on Ada tasks and running on different cores

["Nasser M. Abbasi" <nma@12000.org>]

Assume I am using a PC with say 1,000 cores (may be
in few short years).

If I use Ada, and create many, many tasks, will these
tasks automatically be scheduled to run on as many
different cores as possible so to spread the load and
achieve the most parallelism possible?

Is this something that is controlled by Ada run-time
automatically, or is it the OS that that is in charge here
with which task (i.e. thread) runs on which core?

Will the programmer have to do anything other than just
creating the tasks (and ofcourse protect any critical
section as needed), but not worry about the mapping
of tasks to cores and all the other scheduling issues.

Sorry for such a basic question, but I have not looked
at this for long time.

thanks,
