Dear Professor McCalpin,
Please find enclosed results running Stream_d.f on a:
"Digital AlphaStation 600 5/300".
If you abbreviate the name to fit in the tables, please include the full
"600 5/300", so as to ensure that it is not confused with the older DEC
3000 Model 600. The "5" indicates the 21164 chip (aka ev5), vs. the
older system's 21064 (ev4). The 300 indicates Mhz.
The program was compiled with the switch "O5" (enables software
pipelining), using the FORTRAN compiler V3.8-711, on Digital UNIX V3.2C.
The resolution of the timer is about 1/1000 of a second.
Best regards
