I understand the Intel Math Kernel Library uses an environment variable
to tell it how many CPUs to use. Does that mean I can only set that
number at program start/library load time, and can't change it during
the course of running a program?

Ada 2012 package System.Multiprocessors has been implemented in
gcc-4.6.0. The function Number_Of_CPUs will return the CPU(s) of the
machine currently run on.
