The original poster was nice enough to send me the source code for this
benchmark, and I ran it on our alpha here. I am not sure exactly what
the official name of this machine is, but the following is written on it:
AlphaStation 600 5/266
I ran the benchmarks using different compilers, and my purpose was to see how
gcc compared to the native DEC compilers. This was run under OSF/1 V3.2.
I would be happy to mail statically linked executables to anyone who wants
to see if the speed difference is as pronounced under Linux. The results
are shown below. Please note that the -migrate flag actually causes a
different compiler to be used.
