To echo Matt, it definitely involes some adjustments to the farm! That
may even be a stumbling block for some, or at least a weird surprise.
There's a temptation to think that all you have to do is put a GPU in
your render node and you're golden. Well... that may or may not be
true... depends on all kinds of things. It could be that easy, but it
could also require new hardware entirely. It really depends on what kind
of GPU machines you're wanting to implement, what kind of scale you're
going for. There is no standard way of dealing with this, not yet at any
rate. It's just too early in the life of GPU rendering. We've found that
for us, it's been worth it to devote some time and money to outfit a
portion of our farm for Redshift. Our stuff just looks that much better
in less time. When we saw what it could do for us, it was a no-brainer
to investigate our hardware a little more seriously.
Again, all relative to what you're doing...
We still have racks though.... nothing wrong with a GPU in a rack....

Yeah it would involve quite an adjustment for a trad farm - rackmounts
would be a little useless. I also don't think RS is quite gunning for
the arnold market, its aiming for the smaller shops who don't have
massive render farms.
I rendered 10 million hairs on a character today, ended up using 20Gb
of system ram, as the gpu was only a quadro k4000, but it rendered
pretty fast still. The extraction was the longest part.
Also, just as a quick test, I've instanced 5000 trees using ice
scatter, each tree has 1.2 million polys, so that makes it 6
Billion(?), used 6 Gb system ram. render stats below:
# INFO : [Redshift] Rendering frame 0
# INFO : [Redshift] Scene extraction time: 4.623 s
# INFO : [Redshift] Rendering time: 176.518 s (2 GPU(s) used)
just the usual deformed grid test, nothing exciting:

The ground texture was 20k, that took a little while to convert before
the render started, but after that, I was suprised by the system ram,
particularly as I couldn't even begin to view the instances in the
viewport, bounding box only...

doesn't work like that... i have to convince someone to buy it for
the studio, then the graphics cards you guys talk about... 3
titans!? we don't have those types of investments. we have an
existing farm with cpus and lots of ram. if i want to render a
sequence with redshift... i have to render it on workstations
only. also, i am not going to convert elysium to work for redshift
on my free time ;)
i am sold on the value of redshift, i can see the value clearly! i
just wanting to see how well this 'out of core memory' feature
really works.

Well Steven, for $100 bucks for the Beta maybe you can try
it. Will be awsome to have some feedback on such scene as
Elysium.
