We (Verdix Corp) were able to validate our Ada compiler for the Balance
8000 (12 10MHz-processors, 16 MB memory, Dynix Rel 1.3) in 4 hours and
2 minutes.  The Ada validation test suite consists of about 2500 Ada
tests, verifying the compliance of our compiler to the standard Ada
Language Reference Manual.  Each chapter can be compiled independently
of the others.

This is the fastest validation time for any compiler on any machine by
any Ada compiler vendor that we are aware of.  Our second best time was
on a VAX 8600 running Ultrix, where validation (on a somewhat smaller
number of tests) took about 5 hours and 15 minutes.

Verdix is not part of Sequent, however we do have some contracts with
them.  Sequent loaned us 8 processors and 12 MB of memory to do the
validation.  We believe we are going to sell a lot of Ada development
systems for the B8K -- it is an extremely nice system for doing
software development.  Its major strength is its predictable response
time - even with many users doing CPU and I/O intensive operations, the
B8k stays at essentially load-factor 1.0.  We have seen load factors of
1.2 when only when five simultaneous compiles were happening on a four
processor system.  Even 12 simultaneous compiles barely phased the
twelve processor system.  We see the B8k as an ideal machine for
supporting relatively large numbers of programmers.  Universities are a
perfect match, from what we see.
