Unfortunately BPS has an annoying habit of overwriting the test
output files every time it is run regardless of which test you
actually run. I didn't notice this when I was doing my initial stuff
on RedHat so I lost all the other tests results from BPS. I have
better tests of the hardware since then. We ran HPL on the PowerPC
cluster running both Gentoo 2005.1 and Mac OS 10.4 (mac os was ~ %5
faster on average). I ran IOZone on our XRaid using HFS+ under Mac
OS, and Reiser, xfs, jfs, and ext3 under Gentoo for PPC64.
I also ran tests using Mr Bayes, ClustalW, MPIBench, and several
other in house tests that I had available but all of these tests
where either inconclusive or failed to demonstrate any difference
between the platforms.
I will be doing a bunch of this again here in a bit in order to get
data on our new OS build we are putting into production =)

Yeah, from the numbers it looks as if it would be dependent on the
purpose of the cluster whether OS X or Gentoo would do better. On
ppc,
Gentoo does poorly on the first two benchmarks and also on context
switching. On x86, the first two are more comparable with RH, but the
others, Gentoo has a small to large advantage over RH, just as on
ppc.
First and second benchmarks are dhrystone and whetstone, synthetic
benchmarks.
I'd be wary of these types of benchmarks; they've been cheated
before. I'd like
to see some real-world computation benchmarks.
