So run Linux...
It's not clear if your comparison is right when you look
at floating point arithmetic, especially vector arithmetic.
The date of passage is more like 2005-2006.
When you consider that the largest compute problems
solved anywhere on earth 30 years ago could be solved
on any old podunk desktop, it gets a little shocking, and
I probably reacted too quickly (and botched the calc.).
Still, it's basically next year. Not clear but not far off either.
A Cray-1 wasn't exactly a CM-1 in terms of architectural oddity.
And agreed Linux Is great and getting more so.
