Indeed. Most of the time people want parallelism with OpenMP/MPI. This
is quite low level compared to Ada. Maybe a good approach to this is to
point out that OpenMP/MPI is the procedural way to handle parallelism,
Ada goes far beyond as it has unified the OO paradigm and the
parallelism/concurrency. So in a sense the Ada solution (and Java if I
can pronounce this word here :) is the "revolution" with have seen with
the OO paradigm in the nineties.

Also note that OpenMP is a solution to vector based parallelism, and
this is far from being 100% of the problem. Most scientist applications
are designed with 3 stages : read data, do some computation (not always
vector based), write some data. OpenMP can't be used on stage 1 and 3.
Ada is not imposing any way of designing/implementing the parallelism
and can do great job at the three stages.

I don't know what to do at the moment with that... but I'll work very
soon on converting some sequential applications to parallel applications.
