Hmmm, we have very simmilar machine here (2x opteron 270 @ 2.0ghz), and I must
admit that cinelerra takes
advantage of that quite good, we are using automated splash titles generator,
where user can type text within browser and scripts will glue xml together
and send it to rendering .... , it usually contain a few effects, but
one Athlon XP 1800+ used to have 1 minute 30 secs rendering time for classic
template.
Nowadays, with 4 CPUs, common time is around 20 seconds.
I look forward to see openMosix for 2.6 kernel come out this year, it might be
a pretty
good for cinelerra.
As you have mentioned Adobe Premiere,from my point of view it may use multiple
cpu's , but the program doesn't
have smart logic, so even that won't help .... (try applying a blur efect to an
image which last
a few minutes for example ... it will calculate frame by frame ;) - I gave up
rendering after
waiting an hour and receiving 40 hours expected rendering time - it was no big
deal for fx and it had to be done yesterday
already )(Yes, it used all 4 CPUs ... I've tried same video later on 2 CPU
system and it should complete
in 100 hours)
If have to be less brief, yes , it's sad nowadays, as a new generation of
codecs is out
and HD resolutions are getting trendy, there are no traditional computers ready
for this,
not that even 4 or 8 CPU can be good enough, at least that x264 can handle
threads well.

I have one P4 with HT, so I was wondering if Cinelerra would gain any
extra benefit from that. I was also wondering if I get a new box(es)
should I just put my money into an AMD64 Dual Opteron box with dual core
CPUs? Or should I get a bunch of less expensive Athlon 64s as render
nodes? Is there any "best" approach" for fast rendering?
I own a Dual Dual Core Opteron system (4 logical cpu's), i'm using Opteron 270
cpus.
Based on my experience, although this system is a beast you'll never find
software that can take advantage of its abilities. Current applications don't
really use the 64bit architecture in their coding and most of them don't render
on multiple threads to take advantage of the SMP capability. Its a waste really.
I've been told that Adobe Premier is the only application that can split
rendering in multiple cpus, but i haven't tried it.
