Hi John,
This is the AlphaServer GS320-68/1001 with 32 CPUs. It uses the
same binary as was used for

----------------------------------------------
Double precision appears to have 16 digits of accuracy
Assuming 8 bytes per DOUBLE PRECISION word
----------------------------------------------
Array size = 135000140
Offset = 0
The total memory requirement is 3089.91 MB
You are running each test 10 times
The *best* time for each test is used
----------------------------------------------------
Your clock granularity/precision appears to be 1000 microseconds
The tests below will each take a time on the order
of 65000 microseconds
(= 65 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.

WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.
