For a change, rather than a request for help, here¹s a success story: I
managed to bring a Convex C220 (dual vector CPU mini supercomputer from
1988) back to life. Both CPUs are working, but I¹m running with a
single
CPU because of the power it draws with two CPUs. Next challenges: the
Convex C1, and quad vector processor C240 (not before I¹ve upgraded the
power feed).
Running ConvexOS 11.5.1, it has FORTRAN 7.0.1 installed; I ran a little
benchmark, and with a single CPU the system clocks in at 49.1 MFLOPS on
a
big multiply-add loop (advertised peak performance was 50 MFLOPS per
CPU).
Getting the system to the state where it is now was quite a journey
(though nowhere near as bad as it might have been). If you¹re
interested
in the details, I have a (somewhat long) report of my work on my
website;
if you go to
http://www.vaxbarn.com/index.php/other-bits/603-convex-c220,
there are some links at the bottom that have much more details, as well
as
photos of the system and the boards.
Now I¹m looking for some FORTRAN code that would typically have run on
this kind of computer so I can show people what this kind of system was
used for.
There's something seriously wrong with your site

title of your work is indeed "Feel Like Having Sex Tonight | Best Legal
