This is what we say since many years: A CRAY is a machine to produce
wrong results very fast.

But not the CRAY only, others do also, but not so FAST!

To check the results of Your CRAY, CYBER, VPxxx, etc. You may use
Fortran-SC or Pascal-SC -:) ( not as fast because nobody found accurate
results worth building the neccessary hardware but proven accurate! )

I can post details of this on request.
