Hi!
I tried your benchmark (0.32) on one of our new systems. It's a Compaq
GS-160 "Wildfire" with 16 Alpha-EV67 CPUs (731 MHz) and 32 GB RAM. The
operating system is a field test version of the soon to be released
Tru64 Unix 5.1. Here is the result:

Yes, I used the following flags:
-arch ev67 -tune ev67 -fp_reorder -non_shared -O4
ev67 (aka 21264A) is the processor architecture and -fp_reorder allows
the compiler to change the order of floating point instructions.

Here are the results of my new tests. I compiled one time without any
optimization and the second setup was done with "-O2" optimization. The
results aren't as bad as you might have thought. Either the compiler is
very smart and optimizes even without those flags or it doesn't really
make any big difference after all.
Cheers,
Stefan
