Hi Carmiel,
What did you do with the Ardent (Stardent). That's where all your great benchmark demos are. The Dore' system, the 'Flag' demo. If you want Fortran, I have been working on MOVIE.BYU, a dusty deck, but I have almost got there. It is wireframe and rendered poly animation. It is currently barking at some float to integer in gfortran for the whole thing to come together, but I have the TITLE (3d wireframe of ASCII text working).

Regarding things to run on it, starting with LINPACK is probably a good idea. However, in term of what they were actually used for back in the 1980's, I know that they were popular with the radio astronomy community, starting with the Convex C1. The package called AIPS (Astronomical Image Processing System) was the most popular way of processing data from multi-antenna telescopes like the VLA in New Mexico. AIPS (written in Fortran) is now known as AIPS Classic, to distinguish it from AIPS++ (written in C++) which was developed in the 1990's. There is plenty of information about it on the internet. If you have any difficulty getting the code, let me know as I might be able to help. AIPS is very portable; before the era of the mini-supers, it ran on a lot of VAXen (yeah!!) amongst other things.
