The FPS-164 and its successors almost always ran complete applications, the
"subroutine box" mode was not used by most customers.  This was made possible
by an advanced (for FPS) OS called the Single Job Executive (SJE).

I was thinking MIMD.  Until recently didn't Cray MIMD require
micro-tasking directives inserted in the code on the based on user analysis
of the code?
