NASA/Cray PITEST, and same with Intel HPF mods.
As for the documentation, yeah, I was bored shitless. Just finished a contract involving a Meridian SL-100, in between, wouldn't be doing call accounting on the same for some months yet...
This should run on anything with ANSI FORTRAN-77 and 64 bit (or 60 bit with at least 46 bits of mantissa) floating point, well, anything but the ETA-10 at Ames that killed Control Data. ("It eventually ran"? Yeah, but... Face it, despite a few forward thinking concepts (inspired by Mach and Plan-9? Or DEL for that matter...see wording in RFC-5), which were there, the suits at CDC cursed it from the beginning)
You know, thinking of the ETA-10 thing being cursed from the beginning... What do you think Chippewa Falls was about? They didn't want another wildcatter doing better than them.
A notable POS, Eddie Chiles, once explained wildcatters to me, and it fits. Cray was a wildcatter. A wildcatter was rarely acting dumbfuck cowboy. Educated people making educated guesses good enough to bet the farm on it, when traditionalists scoff. A bit of a wildcatter myself.
Energy Park was simple crosstown traffic. A leash. Lemme guess, short enough to require same day meetings, but long enough to waste half a day every time one is required, just in transit (+probably food and drinks on the way back)? A leash.
With Chippewa Falls, Cray actually forced meetings to be meaningful, I would imagine.
