Hello Professor McCalpin,
As promised a week or so ago, here are the Streams benchmark results for
the new Digital AlphaServer 8400 5/300 system announced today.
As with previous submissions, will you please place the full set of
results (1, 2, 4, 6, and 8 cpus) in both the base table.print and in
parallel.speedup?
Since "Digital AlphaServer 8400 5/300" is rather longer than your
current column width, I've suggested an abbreviation below. The new
naming convention for Alphas includes a model series indicator (8400 is
the refrigerator-sized SMP server); a chip generation number (5); and
the Mhz (300). Over time models may ship with differing Mhz ratings or
chip generations, so the trailing n/nnn is important.
If there are any questions that we can answer about the runs, please
feel free to contact me.
Best regards,
