That's very interesting.  My understanding was that the speedup of the
Cray-1 (I think it is dubbed XMP) was due to a relaxing of the machine's
synchronous operation coupled with a higher yield of chips that operate
in the 8 ns. range.

I had thought that the Cray-2 was to be an improved *architecture* over
the Cray-1.  Is Cray telling why their new architecture could not out-
perform the souped-up Cray-XMP?
