vray and dual-quad core xeon

Hi,

if you would buy such a workstation, will vray be using all 8 cores in the system? or do you need an additional vray lic?

did anyone tested this ? how is vray scaling along all 8 cores ?

cheers,
markus

V-Ray will EAT all its power, so it will work absolutely on 100%.
Go for it!

vray internally supports upto 256 cpus, if im not mistaken. It should perform just fine, and I think other users in the forum has got such rig going already, check out the benchmark thread.

In fact, there is no fixed limit :slight_smile: V-Ray will use as many cores as it finds.

We have a dual quad core and it works beautifully with Vray. Haven’t encountered any problems yet. :slight_smile:

1024 buckets on screen…that would be sick :lol:

7

most buckets i have had so far is 54!

OMG :shock:
Plz, share dozen of 'em with me :smile:

9

no! i like my buckets :wink:

10

i have 44 buckets…SO sexy! :lol:

wow, thanks for all the replies :slight_smile: sounds promising…

another question. For using DR with vray I think I have read that it is limited to 10 cpus per lic. So for working with DR and two dual-quad-cores you need two full vray lics, while a 16 core system just need one? Is that correct ?

thanks again,
Markus

markus, each computer is a connection so if you have 2 dual quads that is 2 connection which leaves you with 8 more!

Not quite; the limitation is on the number of render nodes as machines, no matter how many CPUs.

thanks for the answer vlado, that is great news again.

15

so if you can find some way to cram 100 processors into a machine you can get 10,000 buckets with the 10 computer limit for DR (that might be 2x2 pixel buckets hehehe) i know with linux you can cluster machines. its kinda like DR where all machines work together. i wonder if windows can cluster and if vray would see a cluster as 1 or many systems

Hello Intrinsia,

We have just purchased 2 Dual Quad-cores and the first one we have tested is running slower than our Dual-cores on most jobs. I take it you have not experienced anything like this?

for some things the dual quads will be slower due to the slower clock speeds.

Well I understand that anything single threaded should run slower but I am talking during actual rendering. Some scenes render as slow as our older dual socket single core Xeons from 3 years ago. At those times, all 8 cores appear to be working equally but sometimes running as low as 14% capacity each. Other times, mostly with very simple scenes, they peg at 100% and we get about a 30-50% speed advantage over our dual dual-cores (5160s). Unfortunately, these very simple scenes are rare.

I’m very close to sending these back to Dell and replacing them with Dual 5160s and a slightly better video card which would probably benefit us more as these are workstations first, render nodes only at night.

are you using dynamic memory?

I’ll have to check. I’m not doing the animation, just trying to make sure the guys have the right tools. What is the impact of using dynamic memory or not when rendering on the quads?
