The Convex Ada compiler will produce vector code that is alsmost as good
as the one produced by our FORTRAN compiler. The main problem with
vectorizing Ada code is the fact that the exception handling mechanism
produces more branching possibilities within loops, thus inhibiting
optimization. BTW, we also parallelize our programs either by spreading
tasks across processors or parallelizing on the loop level.
