that rack contains two VAX 4000/700As.
Ahhhh! I get jealous reading that. The 4k VAXen are quite nice and the
700A has around 33VUPs. My best VAXen are a 4k400 and a VS4k90.
The VAXstation 4000/90 is a 42 VUP system and the VAX 4000/400 is a
16 VUP system, so you aren't doing too bad. I seem to recall the
VAX 4000/700A is about 40 VUPs and the /705A is about 45-50 VUPs.

Maybe the /90 is 32 VUPs and the /90A is 38.8, which
would make sense if the
list on DSN is off for both system. What leads me to believe the DSN listing
is in error now is I just ran a test program on a /90, 90A, /400, and /500,
and the numbers for the /90 and /90A are way off from what I'd expect if the
ratings from DSN are correct. I'm going to run some tests this weekend to
try to get better numbers.
What sort of tests do you do? I would be happy to post numbers from my
twin 4000-700As, my 8700 (when I have all the requisite parts), my
6000-610, my 7000-650, my 4000/VLC, my 3100/30, and any other VAXen I have
lying around. I wonder if I could do a VUP test on something other than
VAX and have it mean anything.

I have a VUP program I downloaded from somewhere, but it isn't accurate (for
instance, it only calculates VUPs on one processor of an SMP system). The
real VUP calculator DEC used was a set of programs.
What I use for tests are a few compiles and some other programs and calculate
based on results from a known VUP rating.
I've also tried these tests on an Alpha, but that's apples-to-oranges so
there's really not any correlation.

Cool. This depends on using multithreaded apps, though, right?

I was thinking of something even more different. I was thinking of
calculating a VUP rating for my IBM S/390 G5.
