On Wednesday and Thursday I put together a new dual Opteron-250
system and installed SuSE 9.2 (64bit). Uneventful install but there
were a few issues with rebuilding a few apps (all but one have been

no it's not.
64 bit on a 32 bit processor is smaller because
I've been looking into getting just such a machine to replace my dual 1GHz PIII.
How about posting your system specs.

Well ... If I follow, it sounds to be better off with a couple of nice 32 bits
in cluster mode than a 64 ??

A good 64bit CPU (64 bit data) in a 32 bit OS (32 bit address space)
will be faster.
However, I'll wager the cluster of 32bit beige boxes would be more bang
for the buck than a honkin' 64 bit Bigiron UltraPower. Atleast for
rendering.
Weta used a cluster of 2.8Ghz Xeons, for probably very well

Very true. Some things (dealing with weather data) scale well

At the time the Opteron-250 cpu was $825. Or were you thinking of
the complete system price? I didn't buy a complete system - just
a motherboard/cpu/memo

An off the shelf Opteron or G5 will be a lot cheaper than the same
amount

I think I am gonna be a pain again. Following the setup of my telecine machine
and further readings (yes, I did RTFM on this one), it appears that a movie
media made of several layers does not have the same granularity (which does
obably apply on classic still cameras as well). The blue la
