[dba-Tech] Cray (was: A petition for the development of unmanaged VBandVBA...)

This Cray version came out 1990 -1992
I have used for quick access to a Fortran 77 compiler.

Well you could bug Martin. There is one at Queen's University Belfast
Parallel Computer Centre

Here are course notes on its use from Queen's U
CRAY Y-MP EL Vector Processing and Performance Utilities
Student Notes

The last time I used it for any length of time was on a contract was to 
convert Fortran code that did stress analysis
on icebreaker hull design  from a Cray to an IBM 390. Come to think of 
it the naval architect
I worked with was Finnish and worked on the Russian icebreaker fleet in 
the '70's.

Vector processing  dumps the all or part of the Array KK and LL into a 
vector register and adds the two registers
rather than doing it in a scalar fashion one by one iteration. Hence the 
speed.
DO 10 I = 1, 3
JJ(I) = KK(I)+LL(I)
10 CONTINUE

A book on Fortran Vectorization issues on parallel-vector processors
Cray documentation books are scarce.
